How to Clean and Polish Your Guitar Frets with Fret Erasers - StewMac

An easy way to make your frets shine! Fret Erasers are flexible self-padded rubber blocks embedded with abrasive grits. They're incredibly handyuse them in sequence as a final step on freshly-crowned frets, to erase fine file marks and scratches. The grits are color-coded for convenience. Frets gleam, and play buttery-smooth. I used to wrap abrasive papers around small rubber blocks, but that got a little clumsy. Fret Erasers are simpler and faster.
