Stewmac Fret Eraser (800-grit, blue)

They're incredibly handy—use 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. No more sandy grit or sharp steel wool particles."
—Erick Coleman, repairman and StewMac tech advisor


Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire, with the exception of our Fret Tang Nippers. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.
