NANOSKIN AUTOSCRUB System works fast and achieves professional results with the new advanced rubber polymer technology, which replaces the use of clay bars. It safely and easily removes paint over spray, water spots, fresh tree sap, rail dust and other bonded surface contaminants from the surface of automotive paint, glass, moldings and plastic. Unlike the clay bar, the AUTOSCRUB can be cleaned by simply rinsing off the accumulated contaminates with water. If you drop the AUTOSCRUB on the ground, no worries, just rinse the sponge pad clean and you're ready to keep using it. Easy glides allows for sturdy and controlled handling, unlike clay bars where constant reshaping is required.
