smash the clay together in your hands and and re shape it, and then the clay looks brand new again. i would recommend the clay if you think your wheels are hiding some embedded junk. the speed shine is excellent! make sure you get a bottle of that stuff. it's gold.
if you have already tried our wheel cleaner (item number 11106) or heavy-duty wheel cleaner (item number 11026), the wheel cleaning clay with speed shine (item number 11146) would be the next product we would recommend for you to use to help clean stubborn brake dust.
before using the wheel cleaning clay, we would first recommend to thoroughly wash the wheel.
