UltraSpeed Pro MicroPlus Mop Pad is made of high-performance, dense microfiber that removes the highest levels of dirt from all surfaces. Angled abrasive strips improve cleaning performance, especially on staircases as the abrasive areas cover the full width of the step when using sideways. Use this 16" long mop pad to clean floors, walls, ceilings, stairways, tabletops, desktops, chalkboards & more. Machine-washable construction lasts up to 500 wash cycles.
