The best method for extracting harmful dirt and grit from your wash mitt or brush is to agitate your washing utensil while submerged in water.
Grit Guard® is not a gimmick, it's common sense...when your mitt is in the water, the fibers are fluffed up. When you rub your mitt against Grit Guard®in the water, the fluffed up fibers allow the Grit Guard® to extract the dirt, grit and grime. Once dirt settles in the bottom of the bucket, the Grit Guard®keeps it there by separating the wash water into four quadrants, so the water cannot be disturbed. Also works amazingly well on tile grouting! Fits most 3.5 gallon, 4 gallon, 5 gallon and 6 gallon buckets.
