The Arkwright Blue 12-Piece Dusting Mitts make dusting fast and easy. With a comfortable ribbed elastic wristband, a roomy hand pocket, and a thumb pocket, you can avoid slipping gloves and benefit from a better grip. Clean difficult-to-reach places with ease and control. Microfiber is more effective than cotton because it is constructed from "splintered" yarn that curls into microscopic "hooks." Besides having miniature gripping hooks, microfiber has a positive electrical charge that attracts dust and dirt, which carries a negative charge. Microfiber attracts dirt like a magnet, and the innovative yarn hooks and holds it inside the cloth. Microfiber dusting mitts make quick work of dusting any surface with ease. Machine wash with mild liquid detergent (free of dyes, fragrances, bleach, and softeners). Tumble dry low, and do not iron. Do not use chlorine bleach. Do not use any fabric softener as this may clogs the microfiber and can reduce performance.
