Micro-Fiber polishing cloth acts like a magnet for dust, dirt, and oils, and lasts considerably longer than ordinary cloths. Woven from microscopic fibers, the Planet Waves Micro-Fiber Cloth is 10 times finer than silk, up to 30 times finer than cotton, and 100 times finer than a human hair. 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.
