How to protect a classic car against corrosion and restore the paintwork?

The classic car market has experienced phenomenal growth in the last ten years. A new record was set in August 2017 – Aston Martin DBR1 from the 1950s was auctioned for USD 22.55 million (PLN 91.62 million). In 2018 alone, around 30,000 jobs were delivered to Europe. classic American cars, which clearly shows that this extremely dynamic market needs the help of experts.

Standox, a paint brand from the German city of Wuppertal, has an established position as a professional partner for workshops specializing in classic car restoration. At the same time, in times of economic uncertainty, many people are looking for something specific to allocate funds. Therefore, over the past decade, the value of investments in cars has far exceeded the value of investments in coins, diamonds and old wine. This trend is an ideal opportunity for garages to improve their classic car restoration skills and develop in this market segment.

Olaf Adamek, Standox Brand Manager for Europe, Middle East and Africa – Renovation of classic cars requires both extensive technical knowledge and qualified employees. However, it can be a very lucrative source of income for workshops. The customer community is large, compact and resilient to economic changes. They are often people with extensive general knowledge about classic car restoration, who require professional help from workshops in the field of painting. They must feel that their valuable acquisition is in good hands.

When choosing the best method of restoring a classic car, you need to pay attention to details. Sometimes an order to remove a bit of rust turns into a complete renovation with painting the entire body. Therefore, access to professional support and the right products is the key to success.

Corrosion: the number one enemy of automotive classics

How to protect a classic car against corrosion

The main difference between the paint restoration of a classic car and a modern car is protection against corrosion. Until the 1980s, bodywork was mainly made of sheet metal, which is very susceptible to moisture.

Harald Klöckner, Standox Training and Technical Service Leader EMEA – There is no doubt that getting a complete repair quote is crucial. Once we come to an agreement with the customer on this topic, the main task of the painter is to protect the historic car against corrosion. First of all, it is necessary to ensure that the putty does not come into contact with the bare sheet metal, and to limit the risk of corrosion during the preparation of the substrate. Always use a thin insulating layer between the sheet metal and the putty. Otherwise, the putty acts like a sponge and absorbs water, which then ends up in the metal.

Standox recommends a three-step approach – after the surface has been properly prepared, insulate the sheet metal with a Standox acid-curing primer such as Etching Adhesion Primer U3100 and a VOC filler such as VOC Xtra Filler U7560. Of course, the specifications of the respective paint system must be followed. The VOC filler isolates sanding marks and pores, and helps to even out the surface, making it an ideal base for the topcoat.

Perfect color match

How to protect a classic car against corrosion

As in the case of refurbishing new cars, the digital color management process significantly facilitates color matching in classic cars and improves the accuracy of the entire process. Refinishers have Standox digital color tools at their disposal, such as the Genius iQ spectrophotometer and Standowin iQ software, to perfectly match the color and recreate the original shade and effect of a classic car.

When there is very little original paint left on the body of a classic car due to extensive damage, when the car has been re-painted and the original color has long since been lost under newer coats, or when the color code is unknown, Standox helps the workshop with every step of the color matching and uses its expertise in area of ​​car restoration to help pick the correct color.

– Thanks to the advanced technology of the Genius iQ spectrophotometer and Standowin iQ software, workshops have access to over 200,000 constantly updated color recipes, allowing them to perfectly match color every time. All information is transmitted wirelessly to the scale, explains Harald Klöckner.

Resources and technical support

– In addition to the practical support that our customers can count on, we also provide a wealth of technical knowledge online so that refinishers can develop their skills, adds Harald Klöckner.

Standopedia is Standox’s online guide that provides refinishers with technical information and expert advice on a variety of painting issues, such as refinishing special colors or using new products. Standox also offers an extensive collection of Standothek technical guides that provide practical information for refinishers who wish to develop their skills in classic car restoration.

– Classic car owners have a great passion for their cars, and if the car has been repaired well, the owner will probably come to the workshop with the rest of the cars. Workshops offering a personalized and professional service gain customer loyalty, gain an appropriate reputation on the market and develop their business – summarizes Olaf Adamek.

How to degrease mechanical parts?

The degreasing of metal components, machinery and surfaces is an essential part of a wide variety of industrial and manufacturing activities. Machines must be clean to operate efficiently. Old parts must be cleaned before repair. Items produced should be cleaned prior to finishing, packaging and shipping.

Why clean grease from parts?

The challenges of degreasing mechanical parts vary depending on where the grease accumulates: in your machines, tools and equipment, or on the products you manufacture.

While regular lubrication of parts is generally a good thing, a buildup of dirty grease on industrial equipment can reduce performance and increase the rate at which components wear. And it will increase your production cost.

The risk of grease accumulating on items during production and manufacturing is slightly different. If you don’t remove it correctly at the right points in the process, you risk causing problems in the later stages of production and finishing, especially if they involve coating and painting. Grease can also complicate quality control, whether you do it manually or automatically.

How to degrease parts effectively?

In many cases, the process followed by companies to eliminate fat is long, repetitive and very laborious:

  • Wipe off most of the grease
  • Apply detergent or solvent to dissolve grease
  • Scrub to remove accumulated grease from corners and holes in parts
  • Rinse the surface
  • Dry the parts completely to reduce the risk of rusting
  • And even if you follow this process carefully, there is a risk that the end results will vary from one cleaned part to another.

There is a better way.

Degreasing solutions

The process is similar to the dishwasher you might have in your kitchen:

  • You load dirty items into the machine
  • You select the cleaning cycle you want to run
  • You press Start

The machine cleans mechanical parts, removing grease to a standardized standard that suits you, in a predictable period of time. And while the machine is running, you can focus on other key tasks.

This approach uses modern chemical degreasing solutions that are water-based rather than flammable solvent-based, reducing both workplace hazards and environmental impact. These degreasing fluids are recycled multiple times to minimize costs and include anti-corrosion agents that prevent flash rusting when the cleaned parts dry out.

The Importance of Industrial Mold Cleaning for Productivity and Quality

In a society marked by accelerated industrialization, mass production of standardized products has become the norm.

As such, the key tools are industrial molds, which are used in many processes such as injection molding, compression molding or hot molding. This equipment has a huge impact on the quality and efficiency of production and careful and constant maintenance becomes necessary.

What is an industrial mold?

Industrial molds are tools for giving a precise shape (intermediate or final) to the part or material to be machined, by inserting it in plastic, molten or solid form inside 2 half-molds, the one fixed and the other mobile, in order to determine the shape to be obtained.

Generally made of steel, but also aluminum for prototyping activities, industrial molds have a lifespan that can range from a few parts (even just one) to hundreds of thousands of parts.

When a mold is destined to shape thousands of pieces, constant maintenance over time becomes a fundamental activity in order to guarantee the best production quality, avoid sudden production stoppages and ensure the durability of the mould.

The real cost of an industrial mold

An unmaintained industrial mold can generate major costs for a company: costs related to the downtime necessary to carry out maintenance and repair operations (often carried out by mold makers outside the organization), costs generated by the subsequent restart of production and consequent regulation, loss of profits caused by non-optimized production, an increase in the number of nonconforming batches due to poor quality or even, costs arising from the degradation of the long-term corporate image.

Preventive maintenance then becomes a strategic operation for companies and must be favored within the framework of dedicated processes, scheduled regularly. This need becomes even more frequent in the case of aluminum molds or complex relief molds that wear out more easily. The temperature, type of material and the pressure it is subjected to when inserted into the mold can also impact the frequency of maintenance activities.

The correct use of a mold will limit the need for inspection and revision operations, but will not completely exclude them.

And as with any maintenance process, cleaning is a crucial step.

The industrial mold cleaning process

In order to carry out maintenance, the mold must first be dismantled and checked before moving on to the cleaning phase: parts with a higher concentration of dirt or parts with cracks (cracks) must be cleaned. further control to identify defects in the mold to be rectified.

At this point, it is possible to move on to washing operations to remove different types of residue, including:

  • the release agents used to facilitate the extraction of the parts produced, the residues of lubricating oils and the traces left by the gases generated by the contact between the plastic material in the fluid state and the mold at high temperature, which contain residues that soil the mold itself;
  • oils used in the cold forging of metals;
  • residues of soft metals and lubricating oils used to avoid “tearing” in cutting and thus obtain clean cuts;
  • graphite greases used as a mold release agent in the hot stamping of metals.

The cleaning activity must be carried out avoiding damage to the mould; operations such as sandblasting, shot-blasting or the use of aggressive and potentially corrosive products such as caustic soda should therefore be eliminated.

Moreover, reliance on manual washing processes with rags and solvents leads to unsatisfactory levels of cleaning, especially in the case of molds with complex geometries and small figures.

Considering the considerable impact of an industrial mold on the quality of a mass production, it is advisable to carry out a standardized washing always using the same products and methods in order to minimize the possible variability of the characteristics of the production parts.

So how do you get the desired result? With automatic parts washers that use standardized processes and laundry detergents to thoroughly clean parts for flawless results.

Everything about the right tanker cleaning

Large quantities of animal feed, chemicals, mineral oils and foodstuffs are often transported in tank trucks. Careful cleaning of the tanker truck is required at regular intervals and when the goods to be transported are changed. Only under this condition will the goods reach the recipient safely and in the right quality. Read here what needs to be considered when cleaning tankers.

What is the standard for tanker cleaning?

Tankers are trucks or trailers that can transport free-flowing, liquid or gaseous substances in a built-in tank. Some of them are equipped with hoses and pumps or blowers that are used for emptying. There is a uniform standard for tanker cleaning in Europe that was developed by the EFTCO (European Federation of Tank Cleaning Organisations). In Germany, the DVTI (Deutscher Verband für Tankinnenreinigung e.V.) represents the interests of companies that operate stationary tank interior cleaning systems. There are similar organizations in the other EU countries. In the Netherlands, for example, ATCN (Association of Tank Cleaning Companies Netherlands) takes on the tasks. The aim of the standard is to ensure quality, environmental and health protection as well as occupational safety during cleaning work.

tanker cleaning

What is the ECD cleaning certificate?

Companies that have been proven to use the standard use a uniform cleaning certificate known as the ECD (European Cleaning Document). The advantage of the ECD is that EFTCO tank cleaning codes are used for all information. In this way, the content is comprehensible for everyone involved, regardless of the exhibitor’s language. Permission is required to issue the certificate. This is granted by the DVTI when the cleaning facility is registered and meets all the regulations and conditions of the EFTCO.

How are the EFTCO tank cleaning codes structured?

The EFTCO tank truck cleaning codes consist of one letter and two digits.

The letters have the following meaning:

  • C (Cleaning agents) – cleaning agents

Examples: C01 alkaline cleaning agent, C10 neutral cleaning agent, C20 acidic cleaning agent, C30 caustic soda,

  • E (Extras) – additional work

Examples: E01 entry into the tank, E03 passivation, E04 repair, E15 cleaning with a fuel nozzle, E35 hot air drying, E90 sealing, E95 exterior cleaning

  • F (Foodstuffs) – Foodstuffs

Examples: F01 cleaning with drinking water only, F50 food-approved cleaner, F85 disinfection with hydrogen peroxide, F98 food-approved cleaning system

  • H (Handlings) – Equipment movements

Examples: H01 put on, H50 put down

  • P (Procedures) – Procedures

Examples: P01 cold rinsing, P02 hot rinsing with temperature above 80 °C, P21 rinsing, P30 drying, P60 nitrogen rinsing

  • T (Tests) – Checks

Examples: T01 visual and odor control, T41 conductivity test, T42 ATP test, T43 pH value measurement, T60 lower explosive limit test, T61 oxygen measurement, T90 vacuum test

  • W (Waste) – Waste

Examples: W01 waste product, W50 waste water treatment, W90 pre-cleaning

The EFTCO codes are listed on both the order forms and the cleaning certificates. In the case of orders, they help to clearly record the requirements. Proper execution of the tanker cleaning is documented in the certificates.

food transportation

How is compliance with the conditions and regulations checked?

An SQAS (Safety & Quality Assessment System) is used to check compliance with the conditions and regulations. The basis is a detailed, standardized questionnaire that is filled out by the applicant and evaluated by independent experts.

The individual questions about cleaning the inside and outside of a tanker relate to:

  • the specification of the technical equipment of the cleaning system (construction, inspection, maintenance and repair, calibration of measuring and testing devices…)
  • the work processes of the facility (existence of appropriate work and process instructions, enforcement of occupational safety, use of qualified specialist personnel, monitoring of emissions, responsibility of the driver…)
  • order processing (existence of a proper cleaning order, incoming inspection, selection and implementation of the appropriate cleaning process, final inspection, preparation of the cleaning certificate…)
  • administration (creation and storage of documents, provision of cleaning agents…)
  • special activities (tank heating, tank repair, transfer between road, rail, waterway or sea…)
  • the condition of the business premises (buildings, business premises, stationary facilities, tank cleaning, external washing, stationary storage tanks, waste management)
  • special guidelines for food and feed (suitable cleaning agents, hygiene, avoidance of cross-contamination, securing of valves and openings after tanker cleaning with seals…)

How does the tanker interior cleaning work?

Sophisticated technology for cleaning the inside of tankers is available in modern cleaning systems.

This includes:

  • suction systems for liquids and gases
  • high pressure pumps
  • hot water and steam generator
  • tanks with detergents and disinfectants
  • tank washing heads
  • blower for drying the interior
  • measuring and testing devices
  • waste water and exhaust air treatment

This equipment makes entering the tanks superfluous in most cases. If it is nevertheless necessary, special safety measures apply to protect employees from slipping and falling, from released aerosols, hazardous substances and detached product residues as well as from lack of oxygen.

Incoming inspection and selection of the cleaning process

With the order for the tanker cleaning, the operator of the cleaning system receives the necessary information about the vehicle, the last load, the required scope of cleaning and the required checks of the cleaning result. The cleaning process, the use of special cleaning, rinsing and disinfecting agents and the safety measures to be taken depend on these facts. Therefore, the cleaning company must carefully check whether the information corresponds to the facts found.

Preferred cleaning processes use cold water, hot water or steam to clean the inside of tankers. If these media are not sufficient, special cleaning agents must be used. On the one hand, the cleaning agents used must be effective and, on the other hand, they must be compatible with the dirt. A wrong agent can trigger unexpected chemical reactions with charge residues. With the almost unlimited number of possible loads in tankers, selecting the right cleaning agent is a challenge.

Transportation of chemicals in the chemical industry

Truck tanker chemical delivery tanker cleaning

Customers who are familiar with the cargo can give hints. The manufacturers of agents for tanker cleaning should be listed service providers at the DVTI and offer well-founded advice. Kluthe is also a member of the ATCN. Kluthe’s product range includes solutions for all problems that arise when cleaning tank trucks.

This includes funds for:

  • the interior cleaning with food approval
  • the outside cleaning
  • the removal of latex residues
  • the removal of resins
  • the removal of labels and security labels
  • final check

The effectiveness of tanker cleaning must be proven by tests. The minimum scope includes the visual and odor control on the dome of the tank. Further checks are required for tankers used for transporting chemicals or foodstuffs. This includes, for example, the ATP test. ATP is the abbreviation of adenosine triphosphate. This substance provides energy metabolism in all living cells. If no ATP is detectable, no microorganisms have remained on the inside walls of the tank.

How to remove rust from metal?

Cleaning and protecting metal mechanical parts from rust is a common operation but also necessary in the industry to ensure the proper functioning of the parts and guarantee their durability. Many solutions using chemical and mechanical processes exist today to derust metal parts. However, in addition to being often time-consuming, they generate risks for: the health and safety of operators, damage to parts and the environment.

How does rust form?

Rust forms as a result of a so-called oxidation-reduction reaction, which is a slow chemical process involving the iron molecule (whether in pure iron or an iron-based alloy), present in the metal, exposed to air oxygen and water. It therefore intervenes when the metal is exposed to humidity for a long time.

Certain circumstances will also favor the appearance of rust, such as:

  • Different oxygen concentration conditions such as at sea, where the presence of salt water further accelerates the process
  • The presence of certain metals such as iron which is very easy to oxidize, unlike lead or stainless steel.

As soon as oxidation appears, it corrodes the metal, expands it and causes it to change its appearance. For example, copper turns orange then green on contact with oxidation. Then the oxidation will gradually spread, weakening the metal part until it punctures and crumbles.

Why remove rust from your metal parts?

The consequences of rust forming on metal parts are significant in all industries.

The embrittlement of mechanical parts due to rust can, under the pressure of production processes, reach their breaking point and cause stoppages in production lines or breakdowns in vehicles. This can lead to significant intervention costs, but also in terms of production losses, as well as leading to risky situations for the safety of operators.

The effects of rust thus lead to overconsumption of iron and steel production: more than 15% of steel production would serve only to replace parts damaged by rust, which can represent large sums for the company.

The consequences on the environment are also considerable in terms of the generation of waste from excessively damaged metal parts.

Implementing effective methods of rust removal as part of preventive maintenance along with protective coating can therefore help to ensure the durability of parts, saving money and saving new replacement purchases. expensive equipment.

How to effectively remove rust from metal?

A rustproofing process in industry always includes a process for cleaning mechanical parts and tools upstream, which are generally covered in grease and dust. The parts also require impeccable cleaning so that the adhesion of the protective coating takes place in the best conditions.

Removing rust from metal parts is a complicated task, especially when the surface of the part is not flat.

Fortunately, there are currently many solutions for derusting and degreasing metal parts:

  • some using chemicals such as phosphoric or hydrochloric acid baths
  • some of the multi-step mechanical processes such as sandblasting, shot-blasting or mechanical brushing followed by intense polishing of the parts
  • or other automated industrial cleaning machines such as ultrasonic tanks or immersion machines.

Chemical rust removal process

A chemical deoxidation process based on phosphoric acid, hydrochloric acid or caustic soda makes it easy to remove rust but presents many risks, both for the operators and for the parts.

These products will stop oxidation and remove rust but are highly corrosive and irritating to the skin, eyes, respiratory and digestive tracts if exposed. It is therefore necessary to consult the Safety Data Sheets (SDS) of these products before handling them as a precaution.

They are also dangerous for the environment, especially for the fauna and flora of aquatic environments because they increase the pH of waterways. They are also very aggressive on metal parts and risk damaging them, in particular for precision mechanics where these processes are to be banned. It is also mandatory to trace the end of life of these products according to the regulations.

Mechanical process to derust mechanical parts

remove rust from metal parts

The mechanical way using pickling techniques is the most common way to remove rust from mechanical parts, although they can be time consuming and often tedious for operators.

This includes sandblasting and shot-blasting, which consists of projecting jets of sand or high-pressure iron shot onto metal parts. These surface treatment operations expose operators to risks with the exposure of dust generated and dispersed in the air, which can cause respiratory tract disorders. High-pressure abrasive blasting can also cause severe pitting to appear on the surface of the metal and damage the more delicate parts of the components beyond repair.

There are also techniques using abrasive sandpaper or metal radial brushes but they cause traces of more or less deep grooves in the metal.

All these mechanical operations must often be followed by intensive polishing to achieve a satisfactory finish of the metal parts in order to be able to coat them with protection.

Process using industrial cleaning machines

Faster, simpler, more efficient, industrial cleaning machines can both clean grease and dust from your metal parts but also remove rust effectively.

For this, ultrasonic cleaners are the best solution for degreasing and completely eliminating rust while preserving metal parts, even their most fragile elements. Ultrasounds form pressure variations which propagate in materials immersed in a liquid. These high-frequency vibrations produce millions of tiny microscopic bubbles whose particularity is to immediately implode on contact with the part, releasing high energy which causes the oxides to detach even in inaccessible corners. At the same time, the implosion of these bubbles generates movements in the bath, conducive to cleaning. Thanks to fully automated cleaning cycles, operators can also concentrate on other key tasks.

Cleaning machines using immersion/agitation baths can also be used to remove rust, while keeping the parts intact and without operator intervention.

Upholstery and carpet cleaning with injection and extraction vacuum cleaners

Cleaning upholstery or carpets is usually a delicate task and we recommend always leaving it in the hands of professionals. Not using the right product and method on textile fibers depending on their nature or type of dirt can cause us to even permanently damage the surface. or colour.

Today we can find hundreds of dry cleaning products, foams and endless techniques and home methods on the internet, but in most cases it is necessary to clean with a wet system to clean and disinfect properly, we insist depending on the type of material.

We can find 2 processes to carry out wet cleaning professionally, a manual process indicated especially for synthetic upholstery or fabrics protected with anti-absorbent treatments and a mechanical process, in which we are going to delve a little deeper in this post, which has results. deep hygiene and disinfected and is indicated for upholstery and carpets with absorbent textile fibers.

To carry out this mechanical process of wet cleaning for upholstery and carpets, it is necessary to use professional machinery, in this case injection and extraction vacuum cleaners, capable of introducing or injecting cleaning and extra-disinfecting products into the fabrics or absorbing the same time dirt and dry the surface. Although it may seem like a process similar to using soapy water and a cloth, the result in the case of cleaning with injection and extraction equipment is much deeper and visible almost immediately.

How do injection and extraction aspirators work?

The operation of these machines, despite being for professional use, is quite intuitive.

They can be used as vacuum cleaners for solids or liquids, they normally have a polyester filter, a clean water tank in which the detergent or chemical product that is necessary for cleaning and another dirty water tank are also deposited.

When the clean water tank is filled and mixed with the right product, we have a small suction hose connected to a pump that will absorb the mixture, to be injected through the hose on the surface of the upholstery or carpet, At the same time, dirt and injected liquid are absorbed and dragged away, this also does a drying job, although the reality is that it will always be necessary to dry after washing or let it dry naturally.

Industrial parts cleaning

How to optimize the bath service life

Quality-oriented industrial parts cleaning is the prerequisite for the success of downstream processes and ensures the proper use of finished products. The specific requirements for cleanliness determine which technical requirements must be created for cleaning. Economic considerations when making an investment should also include ongoing operating costs. Modern equipment for process monitoring and bath care can, for example, extend the service life of baths.

Parts cleaning process with aqueous cleaners

Industrial parts cleaning is often done with water in which washing-active substances are dissolved. These bind the impurities from previous processing steps. The water absorbs the dirt load. When the ability to absorb contaminants is exhausted and the cleaning effect is no longer sufficient, the bath is changed. The period between two bath changes is often determined on the basis of experience. If the period of time selected is too long, there will be a loss of quality in the subsequent process steps. To rule this out with certainty, the bath liquid is often changed too early.

The right time can be determined by clearly defining and monitoring parameters that describe the condition of the pool. This point in time can be greatly delayed by using modern processing technology. The aim is to eject the dirt load and used cleaning agents from the bathroom. A number of material separation processes are available for this purpose. The type of contamination and the cleaning agents used are decisive for the selection of suitable processes.

Industrial cleaning of metals

In most cases, metals are machined using cooling lubricants. An oily film remains on the surfaces on which fine chips and dust accumulate. Other contaminants from which metal must be cleaned can be deep-drawing oils, rolling oils and polishing pastes.

Contamination also includes oxidation products such as rust on ferrous metals or verdigris on copper alloys. The agents for industrial parts cleaning must be tailored to the materials of the components.

Processing techniques

The dirt that is removed from the surfaces during parts cleaning can be roughly divided into solid, non-water-miscible liquid and water-miscible substances. The processing methods used to extend the bath service life are based on the state of aggregation and the miscibility with the cleaning solution. Often used:

  • gravity separation,
  • coalescence separation,
  • centrifugal separation and
  • filtration.

If special requirements are placed on the cleanliness of the cleaning solution, more complex processes can also be considered, such as

  • microfiltration,
  • ultrafiltration,
  • reverse osmosis or
  • distillation.

The equipment used can be installed directly in the circuit that circulates the cleaning liquid (full-flow processing) or operated in a bypass independently of this circuit (side-stream processing). In order to optimize the processes that serve to extend the bath service life, both variants are often used side by side. The aggregates in the off-line processing can be switched on or off as required.

Gravity and coalescing separation

Free oils and coarse solids that get into the bath when cleaning workpieces can be physically separated due to their different densities. The advantage here is that the process does not affect the composition of the cleaning solution. The separators consist of a container in which the liquid can rest. Light oils float to the surface and can be sucked off or drained from there. In coalescence separators, this process is supported by built-in components on which the oil collects.

Heavy components from the parts cleaning sink to the bottom as sludge. From there they can be removed with screw conveyors. In three-phase separators, both processes take place in parallel.

Extend bath service life through centrifugal separation

Solids or oils can be removed from the cleaning liquid faster in centrifugal separators, also known as separators, than in gravity separators. The principle is also based on the different densities of the phases. The heavy components are flung against the outer wall by fast rotating movements, while the lighter phase collects in the middle. Both phases are collected and drained separately. The shorter processing time is offset by higher acquisition costs.

Filtration for a longer service life

Industrial parts cleaning often produces dirt in the form of suspended matter, which can be retained in filters. In order to avoid clogging of the pores in the filter material, coarse-pored filters are used first, followed by devices with increasingly smaller pores. Due to the good cleaning performance of the filters, significantly longer bath service lives can be achieved. The disadvantage is that the filter material has to be disposed of together with the dirt.

Microfiltration, ultrafiltration and reverse osmosis

Microfiltration, ultrafiltration and reverse osmosis are among the membrane technologies. The nature of the membranes means that the smallest particles, organic molecules or salts can be removed from the cleaning liquid. In the preparation of baths for industrial cleaning, these techniques only play a role if ultra-fine cleaning with very small particle sizes in the residual dirt is required.

Distillation for water recovery

Distillation is mainly used in the treatment of bath liquids for industrial parts cleaning to recover the water. The process is based on the different boiling points of the components. With this technique, substances dissolved in the water can be separated. It helps to extend the bath service life because the concentration of these substances can be limited to a permissible level.

Monitoring of the bath condition

When monitoring the condition of the bath for industrial parts cleaning, the concentration of the cleaning agent and the amount of dirt in the bath are determined regularly. If the value falls below or exceeds the previously specified limit value, measures are required to restore the permissible operating conditions.

This includes the automatic or manual dosing of the cleaning agent or the commissioning of cleaning stages for the bath liquid that are temporarily used in the bypass. In addition to the bath control, checking the residual contamination on the cleaned parts provides information about the condition of the bath and the effectiveness of the process.

Dry car wash: all the pros and cons

What to do if you really need to wash your car, but there is no possibility to do it at a car wash? In this case, car chemistry comes to the aid of motorists, with the help of which it is possible to put on the marble without using water: the so-called dry car wash. A blurb tells that the method works and is effective, and the main thing is that it is cheaper than usual “car wash”. But do not be flattered and believe everything what they tell marketers.

At one time, this service was offered by enterprising young people in the parking lots of shopping centers. Which, in principle, was quite convenient – while the owner of the car is exploring the galleries of hypermarkets, his car becomes clean in minutes. The method is also used by those who live far away from traditional car washes or simply to save money. But as with everything, washing without water has both pros and cons, which prevail.

Let’s not go into the chemical processes that occur when applying detergent to a dirty body – advertising says something about molecular interactions. But the dirt is really washed off. In addition to everything else, the tool is suitable for cleaning the interior and even the under-hood (before using it, however, it is worth carefully reading the instructions). And after washing, a protective layer is formed on the bodywork, similar to the one that occurs during polishing. However, this is where the advantages of dry cleaning come to an end.

In rainy-snowy season, when roads are muddy and wet, a pretty decent deposit is formed on the body, against which a dry car wash is powerless. And the attempts to take the dirt by brazen force lead to damage of varnish-and-paint covering. And people who are too diligent will be able to prepare a body for painting, using just a microfiber cloth.

It also does not work with bitumen stains. So if you have driven over the repaired section of the road and have stuck them on the body, it is necessary to spend another special means.

But especially intensive dances with tambourine begin when it comes to how to wash the joints of body parts, where traditionally there is an abundance of dirt. The same method of washing doesn’t work here as well. The reason is the inability to wash out the detergent and the amount of dirt that it has collected.

Dry washing is like a crutch – the problem of cleanliness is solved selectively and not always qualitatively. Of course, the method has the right to life, but only if the dirt on the body of your car is not old. For example, on the way to work, the “swallow” was poured with water by a cleaning machine. But even here there is a risk of spoiling the paintwork, for polishing which even at a cheap car wash you will be charged a decent amount of money.

Why do you need a parts washer?

Every workshop is always busy with customers, as vehicles are always in need of maintenance. Small or major breakdowns are always taken care of by the workshop technician, and besides the breakdown of one part or another, vehicles also need routine maintenance.

For service stations an indispensable part of equipment is a parts washer, the productivity of which at times reduces the discomfort of working moments. This equipment saves an enormous amount of time, which is very handy at times of high workload for craftsmen and others.

What parts washing equipment can do

Parts washing is sometimes necessary for small parts, and sometimes entire assemblies require complete cleaning without detailed disassembly. A part washer is tailored for just about every purpose, and can be used to clean a number of parts at once.

There are two varieties of workshop washers. One is a stationary type for procedures of large assemblies and parts such as gearboxes or other large parts. The second type is mobile – which allows you to wash parts directly on the lift, without removing them. The mobile units are also suitable for cleaning of very small parts.

Cleaning chemicals for parts

Parts washers are used in different ways. For instance, for mobile parts washers, adding detergent will be enough, while stationary parts washers need special cleaning chemicals which can wash away rust, oil and other traces of use.

It is worth noting that the chemicals do not spoil the metal, but they are too toxic. Therefore, the liquid should be drained off after washing, so as not to damage the general drainage system or the environment. This liquid must be disposed of in accordance with chemical waste regulations.

The operation of sinks should be carried out in a safe manner, and above all the use of chemicals should be remembered. Hands, eyes and breathing protection should be ensured, and by all means no unauthorised persons should be present in the area.

How to buy a vehicle parts washer

When selecting equipment for washing vehicle parts, you must be aware that sink sizes vary. A single unit or several units may be suitable for a workshop, depending on the tasks and workload of the workshop.
