RCP's Bucket Grate is a must-have for the 2-bucket wash method, helping keep dirt, grit, and grime trapped at the bottom of your bucket and away from your wash pad. By separating contaminants from your clean wash water, it helps eliminate the chance of introducing wash-induced swirl marks into your paint. We recommend dropping it into the bottom of your bucket and rinsing your mitt or pad against it between passes to release trapped debris. This simple addition is one of the easiest ways to protect your finish during every wash. This grate paired with a quality wash bucket, our wash pads, and a plush drying towel will take your detailing experience to the next level.
