MusicNomad's Dusting & Polishing Cloth for Pianos and Keyboards prolongs that fresh-from-the-showroom feel through our superior design, quality and value. Microfiber is a revolutionary material containing 90,000 cleaning microfibers per square inch. The plush higher pile side was designed to lift and trap dust away from the surface. After removing the dust, use the lower pile cloth side with MusicNomad's revolutionary cleaners and polishes to restore the surface's original finish.
