This is a D'Addario Microfibre cleaning/polish mitt. The mitt is designed to fit snugly over your hand, giving you precise control to reach tricky spots like the areas underneath strings, around tuning pegs, and inside cutaways. It’s also ideal for gently cleaning your strings, to extend their life and preserve tone.

The D'Addario micro-fiber mitt acts like a magnet for dust, dirt, and oils, and lasts considerably longer than ordinary cloths. This cloth is made from microscopic fibres which are 10x finer than silk, up to 30x finer than cotton, and 100x finer than a human hair. These fibres 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 D'Addario Micro-Fiber polishing cloth needs only minimal polish, or no polish at all! This means less use of chemicals, which helps the environments.
