How Many Liters of Water Are Needed to Wash a Car?

[LeJeremiah]

At car wash facilities, water usage ranges from 100-200 liters (using high-pressure water guns). When car owners wash their cars at home, typically one bucket of 20-40 liters is sufficient. There are also so-called waterless car wash methods that consume even less water, though these are only for cleaning the exterior of the vehicle. Below are the standard requirements for car washing: Exterior Surface: No water marks on the paint surface, and no dirt or water stains at the seams of various components. Car Windows: No water stains, oil stains, insect marks, or water streaks on the inside or outside of the glass. Interior: Rearview mirrors should have a clear mirror effect with no water stains or streaks; the dashboard should be dust-free, ashtrays should be free of ash, seats should be dust-free, seat cushions should be neatly arranged and not messy, the floor should be free of sand and dust, and cleaned floor mats should have no water marks.
