Wash, wax, and polish vehicles to remove dirt, grime, and stains from both the exterior and interior surfaces. Vacuum, steam clean, and shampoo upholstery, carpets, and other interior surfaces to remove dirt, stains, and odors. Car polishing is the process of removing minor clear coat damage (scratches and swirl marks) using a polishing liquid to flatten the clear coat which increases the gloss-level. The polishing process can be performed by machine or by hand and should be followed by protecting the paint using a wax, sealant or coating.
