For wet stripping of old soiled floor finishes or heavy-duty cleaning use Scotch-Brite™ Floor Pads. These black pads can also be used to clean heavily soiled surface floors such as concrete when used with appropriate cleaning chemicals. They feature an open-web construction which means they are washable and reusable, and resist clogging and loading. Uniform distribution of mineral abrasives throughout every pad and not just on the surface ensures impressive performance and a long, useful life. The combination of highly conformable, individually separated and coated fibres helps provide maximum pad-to-floor contact; all together delivering outstanding cleaning results at a low total cost. Use on round and rectangular rotary swing machines and automatic floor machines running at low speed (175-600 rpm).
