This special double weave cloth is a dust magnet. Its super size (20 x 15″) makes dusting easy. It will clean any high performance finish thoroughly and safely without scratching. If you have a lot of dust, simply dampen the cloth with water or polish. Its own special fabric picks up the dust instead of recirculating it back into the air. Imagine dusting a piano or fine piece of furniture and not having to go back to chase the dust! Mega Dusters are machine washable and compatible with all Piano Accents polishes. Packaged in a reusable ziplock pouch. Color may vary dependent upon availability.
