The Grit Guard Washboard works in conjunction with the Grit Guard Insert in your wash bucket to separate the grit from the mitt! Like it's sister product, the Grit Guard Insert, the Grit Guard Washboard has NO flat surfaces for dirt or grit to be collected. Contaminants are extracted from cleaning tools while rubbing them on the downward stoke against the Washboard.
Particles such as dirt, grit and grime from your wash mitt are the root cause of scratches and swirls in your vehicles finish. 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.
