The Bona Microfiber Cleaning Pad features a unique design with dual zone cleaning action. The dark blue outer fibers break up grime while the inner light blue fibers trap and absorb dirt. The soft microfiber won't scratch or damage your floor, and is safe for use on hardwood or hard-surface floors like stone, tile, laminate and LVT. They are specifically designed for use with The Bona System including the Bona Family of Mops.
