Keep your frets clean, smooth and polished with the D'Addario Fret Polishing System, a simple maintenance kit for guitars, basses and other fretted instruments. Five sheets of reusable polishing paper remove dirt, grime, tarnish and corrosion from the frets, restoring a smooth surface for comfortable fretting and bends while bringing back their polished appearance. The included reusable template fits over the fingerboard during polishing to help protect the surrounding wood, with narrow and jumbo slots accommodating different fret sizes. Easy to add to routine instrument maintenance, the D'Addario Fret Polishing System includes everything needed to refresh worn or tarnished frets and keep them feeling smooth under the strings.
