This pad is highly effective for both cleaning and polishing floors. Ideal for use on VCT, LVT, vinyl, stone, terrazzo, concrete, marble, granite, and rubber. Use on automatic scrubbers or standard speed floor machines up to 350 rpm. Not designed for high speed burnishing. The SmartScrub pad is made of 100% recycled polyester fibers and water based resins. This pad has been designed for use on both sides. Use SmartScrub as a daily cleaning pad in a low speed (175-350 rpm), wet application. Brilliant shine will be maintained or increase over time as used. It will also remove dirt, scuff marks, and imperfections on the floor. SmartScrub was designed to be primarily used on coated floors but can be used on uncoated as well. SmartScrub should be used wet on a low-speed auto scrubber. It is not designed to be used on a high speed burnisher. Continue using the SmartScrub until the azure blue top coat is gone and all that's left is the yellow core on the “work zone” of the pad. You can use plain water or a neutral solution.
