Wax
� �A standard feature of the car wash is the wax arch. The wax that is used in a car wash, which forms a water-resistant coating, is quite different from the wax you would apply by hand. One of the key differences is that car-wash wax is formulated to work on glass, chrome and rubber, as well as the painted plastic and metal surfaces of the car. Also, it leaves a clear, thin film that does not have to be polished first. However, car-wash wax does not provide the same level of protection, nor help to remove or cover up tiny scratches, as standard wax does.
 This wax arch has a triple-foam applicator. Each wax protectant is a different color of foam. |
The wax arch uses one of two methods to apply wax. The first type of wax arch uses a system of foam applicators, the most common being a triple-foam applicator, to apply a foam wax.
 The wax foam is applied to the car in a heavy coating. |
The second type uses nozzles, similar to those of the rinse arch, to apply a liquid wax. In this case, the next step is usually to go through a rinse arch. But when wax foam has been applied, the car usually goes through another set of scrubbers and another mitter curtain before going through a rinse arch.
