The Car Brite Bucket Grate is a car wash filter that keep abrasive particles off your mitt for the perfect scratch-free wash. Rub the wash mitt directly on the BUcket Grate to scrub and agitate any embedded dirt and grime from the wash fibers, then trap it directly underneath the insert. Adding the Bucket Grate to the two bucket method reduces the chances of installing any swirls or scratches during a normal wash dramatically.
