Experts recommend washing the car at least once a week. Otherwise, contamination can badly affect the condition of the paintwork and glass. Particularly dangerous in this regard, organic pollution, which eventually produce an acid that can form on the body of corrosion. Modern technologies make it possible to wash a car quickly and easily using a non-contact method.
Contactless car wash
Every day, contactless car washing is becoming an increasingly popular method of cleaning. The principle of this procedure is that the machine is cleaned under a high-pressure jet of water - the driver should only direct the mechanism. The advantages of contactless washing are as follows:
- The driver does not need to clean the car manually. Simply directing the flow of water - no need to get your hands dirty.
- A contactless procedure, as a rule, is much faster than the usual one and takes about ten minutes.
- This method is safer for a paint and varnish covering of the car as there is no strong mechanical influence. Even a strong flow of water does not provoke the appearance of cracks and chips.
- With proper selection of detergents (car shampoo), you can clean up any contamination, including soot.

How to choose a car shampoo for contactless washing
The properties of the car wash affect the cleaning quality of the car. In this case, an incorrectly chosen agent can not only leave dirt on the body, but also damage its coating. This happens in cases where the driver chooses a tool that is too aggressive for his car. That is why the first rule of contactless washing is a ban on the use of conventional household chemicals - LCP “peel off” after two or three repetitions of the procedure.
Composition of auto shampoo
Each tool, in the first place, is composed of ordinary water. At the same time in order for it not to cause damage to chrome-plated parts, its acid-base level should have a figure of from 6 to 9 units. Various surface elements act as active substances - their name depends on the manufacturer. In this case, a content of not more than 30% of active substances of the total mass of the product is allowed. Complexing agents in the tool perform two roles at once:
- Soften the water, allowing the tool and water to get into hard-to-reach places, and also have a more gentle effect
- Enhance the effect of the surfactant, while not increasing the acidity of the product.
As a part of a car shampoo for contactless washing, various impurities and additives may be present. A foaming agent is considered to be obligatory, and among the optional substances that can increase corrosion protection, as well as wax can be found. The latter is purely cosmetic purpose and is needed to give a glossy look to the surface of the machine.
Types of Autoshampoos
Means for cleaning machines in a contactless way are divided into three types:
- Summer car shampoos. Their peculiarity lies in the fact that they best reveal properties at a certain temperature — relatively high and possible in summer. In addition, they clean the characteristic of the warm season pollution, which include organic, as well as clay and soot.
- Classic (also known as "universal"). These car shampoos for contactless washing are suitable for use at any temperature, but their properties are slightly inferior to those of summer. However, they cope with all major types of pollution.
- Concentrated. They differ technically from other types. Before use, this tool must be diluted with water. In this case, the driver himself decides what proportion to make. If the machine has a stable coating, then the product can be diluted less - it will clean better.
Packing of auto shampoo
The following information should be indicated on the container or box of any quality product:
- Date of production and shelf life. It is necessary to buy only those funds that can still be used, since the use of overdue does not bring results.
- Quality certificates. It is not recommended to purchase car shampoos for contactless washing, which are made without taking into account market standards. They were not monitored, therefore, they may not work at full strength or even damage the machine.
- Label. It must contain the name and logo of the manufacturer, their physical or email address. This allows you to find information about the company to learn more about it.
- Manufacturer. The question of which means is better - import or domestic - does not have a definite answer. At the same time, statistics show that Russian car shampoos are often substandard or forged. However, the country of origin does not directly affect the properties of the product.
Autoshampooes for car
Testing 10 car shampoos for contactless washing
The test took place in the center of Roskhimtest. It consisted in comparing the washing ability, corrosive aggressiveness and the impact on the protective and cosmetic properties of car shampoos.
The test involved ten car shampoos for contactless washing:
- PROFI MAX FOAM 24/32;
- PROFI MAX CARRY EXTRA;
- КОСМЕТИК-АВОО FOAM MASTER;
- КОСМЕТИК-АВО DF-190;
- THE DLS-150;
- TO DECO;
- CHIMIGAL STARCAR;
- CHIMIGAL GEOS;
- MA-FRA SIPERMA FRASOL;
- MA-FRA JEDY.
To study the detergency of each tool was diluted with water in the ratio of 1 to 30. As a sample of the paintwork was applied ten identical parts from the body of one machine. The resulting solution was applied to the contaminated surface with the aid of a foaming device. After 5 minutes each sample was rinsed under a tap. The detergency was estimated at the rate of the remaining mass of pollution in grams per square meter.
To simulate pollution, two trains were prepared that were applied to the body samples. A yellow pigment was added to them - this is necessary in order to make the pollution more visible against the background of the black fragment.
Each sample was applied the same amount of mixture that simulates pollution. It is distributed evenly throughout the LCP. Further, the samples were kept in an oven for 1 hour at 60 degrees Celsius and for 18 hours at 20 degrees Celsius.
The test took place in accordance with GOST "Paint coatings. Test methods for resistance to static effects of liquids ". The prepared samples were immersed in a solution of car shampoos for contactless washing and kept for 5, 30 and 60 minutes. After that, the samples were washed and dried. The test results were summarized both visually and using a gloss meter.
A study was also made of the effect of car shampoos on aluminum coatings. The sample was a regular foil. Samples were contaminated and then dried. Then the foil was cleaned with auto shampoos. We checked both their aggressiveness (the criterion was the mass and appearance of the foil) and the visual condition. There were two tests: an hour and a week of soaking.
PROFI MAX FOAM 24/32
Thick pink liquid with a slight ammonia odor. When mixed with water, it quickly forms a voluminous foam. Restores the brilliance of the sample almost to its original state.
When applied to aluminum, foam was poorly formed in the solution. Plate lost in the mass of 0.04 grams. After a week, the aluminum went dark. After washing, the dusty sample had a contamination of 52 grams per square meter. Oiled - 14 g / m2.
The tool has strong alkaline performance - with long exposure, it leads to darkening and corrosion. With a short-term exposure does not cause harm. Car shampoo copes well with oiling, but poorly with dusting.
PROFI MAX CARRY EXTRA
Car shampoo for contactless yellow washing. It also has an ammonia smell. Foams well, but unstable. Restores shine paintwork.
In contact with aluminum, foam was formed intensively. During the hour of exposure, the plate lost 0.08 grams in weight. After a week of testing, the aluminum sample darkened and found white scurf, and the solution dimmed. The paintwork samples were cleaned as follows: dust left pollution at 29 g / m2and oiling - 31 g / m2.
In case of short-term contact with aluminum and paintwork, the tool does not provoke damage. At the same time long contact is extremely undesirable. The car shampoo has an average potential in cleansing both contaminants.
КОСМЕТИК-АВОО FOAM MASTER
Thick yellow liquid. It has a slight smell. Foam is well formed and stably held. Glitter sample paintwork restores completely.
When processing aluminum foam is poorly formed. The plate lost 0.03 grams per hour of the experiment. A week later, the aluminum darkened and in some places strongly dissolved. After oiling 23 g / m2, and after dusting - 19 g / m2.
Research shows that car shampoo has a caustic alkaline environment. It is not recommended to allow prolonged contact with aluminum. Acceptable laundering both types of pollution.

Thick green liquid with a slight odor. Good, but unstable foams. Returns shine to contaminated paintwork.
Contact with the aluminum plate provoked abundant foaming. The sample lost 0.07 grams per hour. During the week of exposure, aluminum is very dark. From the oiling layer remained weighing 21 g / m2, and from dusting - 3 g / m2.
Short-term contact car shampoo does not have a negative impact on aluminum and paintwork. At the same time prolonged contact with aluminum leads to darkening. The tool perfectly removes the sand-cement layer, but mediocre oil.
Thick dark green liquid with a slight odor of flavoring. Well and stably foams when mixed with water. Excellent returns shine polluted paintwork.
In contact with aluminum, intense foam formation is observed. During the hour of testing, the sample lost 0.07 grams of weight. A week later, the aluminum plate significantly darkened. Cleaning from oiling leaves a 10 g / m contamination2. From dusting - 3g / m2.
Short-term contact with aluminum and paintwork does not cause deformation. The tool has coped well with both oily pollution and cement-sand.
Thick blue liquid with a pungent odor. Volume and stable foam. Cleans paintwork, returning them the original shine.
Contact with aluminum leads to poor foam formation. In an hour of the experiment, the plate lost 0.05 grams. After a week, the aluminum sample, immersed in the solution, significantly darkened. Residual contamination after cleaning with an agent was 9 g / m2 for oiling and 11 g / m2 для dusting.
The composition has a sharply alkaline environment. Short-term effects on aluminum do not have negative consequences, but with a long contact the metal plate is covered with corrosion. As for the paintwork, the car shampoo for contactless washing does not damage it. Very well copes with the task in both cases of pollution.
Tool for professional use. Thick yellow liquid with a strong odor. It foams well when mixed with water and forms a stable foam. Allows you to return shine paintwork after washing.
