CAR POLISHES are products used to clean and protect the exterior of a car. Waxes are one type of car polish, which is used to create a protective layer on the car's surface that helps to repel dirt, dust, and water. Waxes also help to restore the shine of the car's paint job. Other types of car polishes include sealants, glazes, and polishing compounds, which all help to clean and protect the car's exterior.
