Car detailing and valeting businesses clean and care for the interior and exterior of cars. Valeting commonly involves washing the bodywork, wheels and glass, drying the vehicle and cleaning the cabin, including vacuuming carpets and seats, wiping surfaces and attending to door shuts. Services may be offered as one-off cleans or at regular intervals, and some providers work at the customer's home or workplace. Detailing usually involves more thorough cleaning and finishing, with work chosen to suit the vehicle's condition and materials. It can include deep cleaning upholstery and carpets, treating leather, removing stains and odours, cleaning engine bays, and refining paintwork to reduce the appearance of light scratches or swirl marks. Businesses may also apply waxes, paint sealants or ceramic coatings to help protect exterior surfaces. The products, processes and results vary, so the work may be tailored to the vehicle and the customer's requirements.
