To get those particles out of your sponge or mitt, you need the Bucket Barrier. The raised radial surface fits in the bottom of any 5 gallon bucket and extracts grit from your wash mitt or sponge when you drag it across the Bucket Barrier. The dirt settles at the bottom of the bucket so your wash water stays clean. This Bucket barrier does not fit the Grit Guard Washboard.
