Yeah we couldn't think of a better name for the product...
You get it though..
1. Clean car
2. Dirt gets trapped in microfibre sponge
3. Sponge goes into pail with detergent
4. Some dirt gets dislodged (some doesn't)
5. Take to car
6. Repeat steps 1 to 5
7. Clean car and install scratches
Stop this at step 4 by placing The Grit Guardian at the base of your pail.
Not only does the dirt settle to the bottom of the pail, as the sponge is rubbed against The Grit Guardian, more dirt is dislodged giving you a cleaner sponge and a lower likelihood of inadvertently scratching your car giving each polish and wax session a longer life.
