The Mint Blue Mitt Slide is not an ordinary water dirt filter. It fits almost all washing buckets and provides a vertical surface to clean your wash sponge, mitt, pad, towel, or mop. Just rub against the vertical side of the slide, contaminants are dislodged from your washing tool and sink beneath the grit insert at the bucket's bottom. Remember dirt and grit from your wash sponge are primary causes of scratches and swirls on vehicle finishes. By using the Mint Blue Mitt Slide, you ensure your wash mitt remains clean and scratch-free with each dip in the bucket.This system effectively keeps harmful dirt at the bottom of the bucket, under the grit guard, away from your washing tools and your vehicle's paint. This minimizes the chances of inflicting scratches and swirl marks on your vehicle.
