The re-usable G3 Professional Deep Clean Clay Mitt uses an advanced rubber polymer technology that easily removes ingrained dirt, bugs, tar spots, and dulling pollutants from paintwork, windscreens and headlights. It is an easy-to-use alternative to a traditional clay bar and lasts up to 5x longer than traditional clay bars. Unlike clay, it does not need to be thrown away if dropped. Must be used with a lubricant, preferably G3 Pro Bodyshop Detailer or water. This allows the mitt to glide over the surface, picking up the microscopic contaminants. The result is amazingly silky smooth surfaces thoroughly prepared for paint renovation or waxing.
