A clay pad for car washing is a tool used to remove contaminants from the surface of a vehicle's paint. It is part of a process called "clay barring" or "clay treatment," which is typically done after washing the car but before applying wax or sealant. The clay pad, often made of a synthetic material embedded with a clay-like substance, is used in place of traditional clay bars to make the process faster and easier.
