Hello! I have a problem, I use the tire care Endurance High Gloss from Meguiars. With the middle of the car there is always something stuck on the curb when I drive over it. The curb is now richjg nice black and the owner of the driveway has complained already. How can I get the stuff out of the stone again? 200 bar high pressure cleaner with dirt cutter unfortunately can not… mfg I3lacIe
