Your job duties include all aspects of washing the interiors and exteriors of cars. For car interiors, you dispose of trash, vacuum floors and seats, polish surfaces, and clean the inside of the windshield and windows. For car exteriors, you pre-soak, soap, rinse, and dry the car. You also apply wax and clean tires. A car wash, or auto wash, is a facility used to clean the exterior, and in some cases the interior, of cars. Car washes can be self-service, full-service (with attendants who wash the vehicle), or fully automated (possibly connected to a filling station). A car washer is a component in a car that functions to spray cleaning fluid onto the windshield. This cleaning fluid is used to clean the windshield from adhering dirt and dust.
