Clean floors made from stone, concrete, VCT, marble and other porous surfaces with 3M™ Melamine Floor Pads. These highly effective pads make light work of ingrained dirt, and unsightly scuff marks, cleaning away most dirt and marks with water alone. This means they are environmentally preferable, with no cleaning additives or chemicals required. Clean up to 1000㎡ for single disc cleaning machines and 10,000㎡ for scrubber driers.
