Koch-Chemie's Clay Spray is a mild, low-residue lubricant that is free of coating defects. Effective for use with quality clay bars and clay towels. The excellent lubricity minimizes surface scratching during cleaning. Unlike other lubricants, it does not leave behind any film. The residue is easy to wipe away with a microfiber cloth. Thanks to the specialized formula, the clay bars or pads do not dissolve and last considerably longer than other clay lubrication sprays on the market.
