A simple and automated type of car wash that is typically coin-operated or token-operated self-service system. Newer self-service car washes offer the ability to pay with loyalty systems, like our Inotec. The vehicle is parked inside a large covered bay that is equipped with a trigger high-pressure sprayer and a scrub foam-brush. When customers insert coins or tokens into the controller, they can choose options such as soap, insect 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 are necessary to start the equipment. These facilities are often equipped with separate vacuum stations that allow customers to clean the inside their cars. Some self-service car washes offer hand-held dryers, a somewhat new feature.
