What is a contactless sink?
Touchless car washing is a modern, highly convenient method that ensures the most gentle treatment of your vehicle’s paintwork while effectively removing all kinds of dirt and contaminants.
FEATURES OF TOUCHLESS CAR WASHES
Many drivers refer to self-service car washes as “touchless,” reasoning that there is “no contact with staff.” And while it’s true that all self-service washes are touchless in that regard — that’s not the full story.
The term “touchless” actually comes from a different source — the introduction of a special category of cleaning chemicals known as active foam. This formula allowed the industry to abandon traditional cleaning tools like brushes, sponges, and cloths. These specialized additives chemically loosen and break down dirt without damaging the car’s surface and are then rinsed off with water. Hence, the name “touchless” — meaning no mechanical contact with the vehicle during washing.
GENERAL TECHNOLOGY OF TOUCHLESS WASHING
Although specific procedures may vary slightly between different touchless car wash systems — depending on the equipment and cleaning agents used — the basic operating principle remains the same.
The vehicle (sometimes pre-cleaned with compressed air or water) is covered with active foam using a compressor or a manually pressurized spray gun. The foam generator creates a snow-like substance that quickly and evenly covers the entire car body.
The foam — an alkaline solution with strong absorbing properties — is activated over the next few minutes. The following steps include rinsing off the dirt-laden foam, fresh water rinsing, and drying.
It’s important to remember that leaving the foam on the vehicle for too long is not recommended: if it dries, it can leave behind white spots that are difficult to remove with water alone — only quality polishers will work. For the same reason (to avoid premature drying), foam should not be applied to a hot car surface. Another common cause of spotting on the paintwork is incorrect dilution of the concentrate during preparation.
