Shinemate Diamond Grit Guard

Does the job

Perfect fit for most standard 5 gallon buckets and filters and a good medium to rub wash mitts on. Plastic is solid and dirt doesn't seem to get stuck on it.

Fits a 5 gallon bucket perfectly

If you go an extra bucket lying around and don't need a car wash set, It's worth picking one of these up. Works well for keeping the dirt that accumulates at the bottom from swirling back up into the wash mitt.
