When a motorist sends his car to the wash, he hopes from the very beginning for an extremely positive result of this process. However, many do not even realize that an ordinary procedure can turn into a bunch of unpleasant consequences for the car body, its electronics and not only. This happens due to the numerous mistakes that are made every now and then during cleaning.
1. Tanks are not afraid of dirt, but cars are afraid
There is a popular thesis that a layer of dirt protects the paintwork. In fact, this is a downright stupid myth. The more dirt, the more difficult it is to wash the car, even at the car wash. And this, not to mention the fact that such a "fur coat" of chemical reagents, in principle, does not reflect in the best way on the condition of the car. The problem is that you cannot wash the car with brushes when it is heavily soiled. First, you will have to wash it by hand, and this is already buying an additional option at the sink. In order to avoid such problems, the car should be driven to the appropriate institution about once a week.
2. Temperature difference
In summer, do not forget that the heating of the body provokes the formation of microcracks in the paintwork. Before washing, the machine should stand in the shade for 5-10 minutes to cool down. Otherwise, the brushes will pave a direct path to corrosion. Do not forget about temperature changes in winter. An instant drive into the cold is fraught with the fact that some moving elements, for example, locks or doors, will freeze in the car.
3. Underdried
An error that directly stems from the previous one. The car at the car wash must be thoroughly dried not only with compressed air, but also with rags. Do not forget to demand this from the washing personnel. It will also be useful to make sure that employees have blown through all secluded areas, for example, in the mirror fixing area. Otherwise, the car will immediately collect unnecessary dust, and in winter it will be covered with a layer of ice, which will not be the best way to affect the body and moving elements.

4. Hood procedures
Seeing a clean engine bay is just a joy. However, do not forget that washing the engine is a separate procedure that requires appropriate qualifications from the station employee. In addition, you should not try to do this cleaning yourself, especially if you have not the slightest idea of how it is actually done. It is best to entrust this work to the appropriate specialists.

5. Close contact
During washing, the "Karcher" nozzle should never be brought too close to the vehicle. Do not be too lazy to follow how the washers work. The water flow pressure can reach 140 bar. Needless to say, this is a serious test for paintwork. The spray gun must be at least 25 cm and at an angle much less than 90 degrees.
