Conventional cleaning pads often fail to properly capture dust and dirt, leaving residues behind. The Bona microfiber cleaning pad features a unique two-zone design. The dark blue outer fibers gently loosen dirt, while the light blue inner fibers absorb it. The mop cover is machine washable and can be attached to all Bona mops thanks to its Velcro surface. Made from over 90% recycled material. Patented two-zone microfiber pad for optimal cleaning. Professional quality for streak-free results. Gently absorbs moisture and dirt. Gentle on floors and leaves no dulling scratches. Washable in the washing machine up to 500 times.
