The D'Addario Fret Cleaner and Buffer is a two-step fret maintenance system designed to remove grime and oxidation from frets without creams or chemicals. The kit includes a protective fret guard, which shields the fingerboard while working, and three dual-sided buffing pads with a hard sponge core made from premium EVA foam — one side for cleaning, one for polishing. The result is smoother, less friction-prone frets, improved playability, and a longer working life for both the frets and the strings running over them.
