A car wash or auto wash is a facility used to clean the exterior and, in some cases, the interior of motor vehicles. Car washes can be self-serve, fully automated, or full-service with attendants who wash the vehicle. They may also comprise a series of cleaning methods and equipment including pressure washing, manual or automatic brushing, soap, drying, and waxing. Services may be paid for through various means, including coin deposit, cash, card payment, or mobile payment applications.
