This uniquely shaped brush makes cleaning your foam and microfiber pads a breeze. While the pad is still on the machine buffer, run at the machine's slowest setting and gently brush the surface clean. It's a quick, easy, and effective way to remove contaminants from pads like dried polish or compound residue or microscopic paint or clearcoat particles. Removing these particles from your pad will help prevent micro-marring your vehicle's paint surface.
