The contaminants are extracted from your cleaning tools as you rub them on the downward stoke against the Washboard. By using the Grit Guard Washboard together with the Grit Guard Insert you are insuring a clean, scratch-free wash mitt every time you go back to the bucket for water.

All of the potentially harmful dirt settles in the bottom of the bucket, keeping it away from your mitt and away from your paint. This simple and cost effective method protects your precious painted surfaces from being scratched and saves your paint from swirl marks and scratches.
