Genuine joe 19″ polishing floor pads, white, 5/case – gjo90519 polishing floor pad is designed for dry polishing and can be used with a fine-water mist to create a higher gloss. Open web design allows dirt to enter the fiber and resist soil load on the face of the pad for maximum use. Resiliency allows pad to remain flexible to reach depressions. Finer denier fibers with softer resin are nonabrasive for light polishing. Floor pad is designed for use at speeds between 175 to 350 rpm.
