Manual contactless car wash
This is a relatively new direction of car wash, it originated about 10 years ago and is not very popular yet.
Such a wash implies car coating with the help of a “foam-gun” with special foam.
Then this foam is washed off with plain water and then the car is dried by a high-power hairdryer.
The obvious advantage of such a car wash is the lack of manual wiping, when an employee, without calculating the strength, can accidentally damage the painting of the car.
Rags also in order to optimize the company’s assets are often used longer than the prescribed period.
The downside is the same human factor, when the owner of a car wash really wants to reduce production costs, and he forces his employees to save detergents, to reduce the time for drying (saving electricity).
