Baroque Fret Erasers 180 & 400 & 1000 Grits, Guitar Fret Polishing Abrasive Rubber Blocks, Set of 3 Grits

I decided to try these out on an old T. Haruo Model 80 acoustic guitar that I had bought back in the 1970s. I leveled the frets first and then crowned them with a fret crowning file that I'd also just bought. When I was done crowning the frets, I used the coarser fret eraser on them. Without taking the trouble to look it up, I think the grits on the erasers are 180, 400 and 1000. The 180 grit does a very nice and quick job on the frets. I didn't notice too much more improvement with the 400 grit. Of course, there was some improvement, but the improvement from crowning the frets with a file and then to polishing them with the 180 grit eraser was the biggest and quickest improvement. In fact, you could probably get by with the 180 grit eraser alone. I didn't care too much about the guitar. I hadn't played it in decades. I didn't care if I ruined it. However, I found out that I was able to do a perfect job on the frets without even touching the fingerboard. Don't do this, though! I had a box full of various Martin acoustic strings, so I went ahead and strung up the guitar. Surprisingly, the guitar sounds beautiful. The workmanship, if you look close, is no where near the quality of a Martin guitar, but the sound is probably as good as an upper end Martin, surprisingly. I know because I also have a Martin HD-28 acoustic guitar. The T. Haruo guitars, like many other guitars, were styled after the Martin guitars, especially the Martin Dreadnought guitars. The Dreadnoughts are the largest or "jumbo" Martin guitars. Anyway, if you are going to use the fret erasers, you probably care about your guitar or you wouldn't be taking the trouble to polish the frets. In that case, I'd suggest using masking tape between all the frets that you are working on. You can buy different widths of masking tape. You'll need a narrow width for the higher frets, so it's best to buy one roll of wide width and one roll of narrow width tape. I doubt very much that the fret erasers are going to hurt your frets, but the 180 grit will brighten the dirtiest and nastiest frets very quickly, for starters. If you want to spend enough time, you can bring the frets up to a pretty good shine using the other erasers.

Superior product

Did what it supposed to used it on a acoustic guitar that very much needed a setup done i previously bought a acoustic that was terrible it need a complete fret job had bad and also duplicate strings so i got new strings done a entire fret work job and made it all as good as i could with this and othrr toolkit set and made the guitar sound descently good now and the guitar was under 50$ so thats made me happy

These really handle like rubber erasers, they're not all that flexible, just a little bendable. They also shed soft particles like a rubber eraser that you will need to clean off, they really show up on a maple fingerboard. These will NOT bend enough to conform to frets like the sponge-type abrasives. They WILL bend enough to get a nice finish on the top of a crown. You can get the sides of the frets by placing the edges against the side of the fret and rubbing side to side while twisting around the shape of the fret. Pretty easy to do. I wish there were a grit in between 400 and 1000, or maybe a 1500 instead of the 180, which is just as easy to do with conventional sandpaper. Very high priced, but seems like they will last me forever, as I am not a pro that will be doing tons of guitars. I used these on one neck with stainless frets and they are fine.

I am very happy with these fret erasers. They are easy to use and they make quick work of cleaning and polishing frets. I am no luthier, but as a working musician and private instructor, I do a lot of setups for myself and my students. After over ten of my own projects, a buddy borrowed these erasers. He liked them so much, he bought a set of his own. I like them and recommend buying them.

I purchased a travel guitar that had a good deal of "fret sprout" - the poor little guy sat in a box for 3 years and dried out the rosewood, and playing it felt like the mfg. bought the frets from the Ginsu Fret Company - they would actually cut your fingers! These "erasers" were super helpful in smoothing down the sprout and polishing the frets (I used a file also, to fix the big issues first). I also used them on my other guitars and my wife's mandolin, and they performed great. They really clean up the frets well, and make them silky smooth again.

Work pretty well, though as they get a little dirty, they seem to lose their effectiveness a bit. Could drop the 150 and add a 2500 grit for a more effective set, as I still have to go back and polish after going through all three. Can't beat the time savings for the money here if you're working on something you don't need to be able to see yourself in the frets of.

These are absolutely great! They bring your frets back to life with very little effort.

Handy grit erasers for cleaning guitar frets works as expected.

Great product ! A bit smaller than I thought the pieces would be , overall though they do what they are meant to do .

Overpriced but good

Works great for quick spot polishes of frets. Arrived on time and in good order
