A clay mitt for car washing is a detailing tool used to remove contaminants from the surface of a vehicle's paint. It is a mitt or glove-like tool that combines the functionality of a wash mitt with the decontaminating properties of detailing clay. The clay mitt is made of a clay-like material on one side, which helps in effectively picking up contaminants like dirt, grime, and other particles that have bonded to the paint.

Clay mitts are designed to be used with a lubricant to glide over the paint surface, providing a convenient and efficient way to decontaminate the car's exterior. They are reusable and can cover larger surface areas compared to traditional clay bars, making the decontamination process quicker and easier. Clay mitts come in different grades to suit various detailing needs and are effective in achieving a smooth and clean finish on the vehicle's paint by removing embedded contaminants.
