Camco's Wash Bucket Insert allows you to efficiently wash your car, boat or RV and protect it from surface damage. It is designed to help remove dirt and debris from your wash mitts, sponges and brushes—trapping the grime at the bottom of your wash bucket. The grid surface scrapes dirt and grit from your cleaning supplies, helping prevent streaks and scratches to your vehicle's finish. This product measures 10 3/8-inches in diameter and fits inside standard 5-gallon buckets. Constructed of durable plastic.
