Self-service car wash

A simple and automated type of car wash that is typically a coin-operated or token-operated self-service system. Newer self-service car washes offer the ability to pay with credit cards or loyalty cards. The vehicle is parked inside a large covered bay that is equipped with a trigger gun and wand (a high-pressure 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 clear water 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; in most instances, a minimum number of coins is 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.
