A car wash is a service designed to clean the exterior — and sometimes the interior — of vehicles. These services can range from basic hand washes to fully automated systems that handle washing, rinsing, and drying. Many car washes also offer extra services like waxing, tire cleaning, and interior vacuuming. Customers may choose between self-service options, where they clean their own vehicle using provided tools, or full-service washes, where professionals do the work for them.
