I seem to be on quite a car wash mission.

This is the best type of self service car wash.

Newer self-service car washes offer the ability to pay with credit cards. The vehicle is parked inside a large bay that isequipped with a trigger gun and wand (sprayer) and a scrub foam-brush. When customers insert coins or tokens into the controller, they can choose options such as soap, tire cleaner, wax or rinse all dispensed from the sprayer, or scrub the vehicle with the foam-brush. The number of coins or tokens inserted determines the amount of time customers have to operate the equipment, however in most instances, a minimum number of coins are necessary to start the equipment. These facilities are often equipped with separate vacuum stations that allow customers to clean the upholstery and rugs inside their cars. Some self-service car washes offer hand-held dryers, a somewhat new feature.
