Clay blocks are an effective detailing tool used to remove contaminants from the surface of a car's paint.

They are similar to clay bars but typically offer larger coverage areas and are easier to handle due to their design.

Clay blocks are used with a lubricant to glide over the paint, picking up embedded contaminants like dirt, industrial fallout, and residues from tree sap or tar. After claying, the paint surface feels smoother and is ready for waxing or sealing to enhance its shine and protection.

Using a clay block is recommended periodically to maintain the cleanliness and smoothness of your vehicle's paint.
