Auto detailing is the performance of an extremely thorough cleaning, polishing and waxing of an automobile, both inside and out, to produce a show-quality level of detail. Besides improving appearance, detailing helps to preserve resale value of a car.
Today, the United States may have more than 50,000 detailers in operation. Some are franchisees of national auto detailing chains. Many have no actual business address, instead working as mobile operators or in vacant parking lots. Detailing/valeting can be practiced for personal satisfaction, and it is also performed to prepare a car for car shows that feature the appearance of cars.
