The D'Addario Fret Polishing System is the secret to making any guitar or basses frets shine like new. Contains 5 sheets of reusable fret polishing paper and includes a polishing template to place over the fretboard during polishing. Within minutes you can remove all the dirt, grime and corrosion from your frets that kills the tone and feel of your instrument. The Fret polishing system is one of the easiest ways to improve your instruments performance, tone, and appearance.

The polisher I used made a big difference, it doesn't even take much effort, just a few passes with the polisher and you have a completely different and smooth key. I especially recommend it for quick care/setup before playing if the keys are dirty.
