To use Cleaner Clay, work on a clean vehicle in a shady area, on a cool paint surface. Spray a 1 ft square area with lubricant and rub the bar lightly back and forth. It will grab at first, but keep rubbing. Keep the surface wet/lubricated. When the bar glides freely, the surface is clean. Wipe away any residue with a microfiber towel and move on to the next section. Store your clay bar by wetting it with lubricant and sealing it in a plastic bag in its original jar.
