Woven from microscopic fibers, D'Addario's Micro-Fiber Polishing Cloth acts like a magnet for dust, dirt, and oils. The fibers are woven into masses of tiny "hooks & loops" which cut through stains, attracting and absorbing dirt, smudges, and microparticles that ordinary cloths cannot reach or remove. Best of all, the Micro-Fiber Polishing cloth lasts considerably longer than ordinary cloths and needs only minimal polish or none at all, meaning less use of chemicals. When the Micro-Fiber Polishing Cloth needs cleaning, simply wash in mild soap and water, rinse out, and hang to dry.
