JIM DUNLOP FBA Miracle Cloth 12" (MCR12)

I’ve collected about 30 fretted instruments and repaired many more. Had previously been using a dremel and polish for most of my fret polishing. Ran out and remembered the gorgomyte cloth was a thing a friend recommended, couldn’t find it anymore and this was recommended as a replacement.Got them in and had a neck that needed some polishing. Taped up the neck and this made really short order of the job.Super happy with the ease of use and application. I cut it into quarter pieces and used one for the job moving sections of the cloth when it felt like it was bogging down. It will blacken. This happens when polishing metal via other methods as well.Overall a couple quick swipes and the frets looked great.With how much came in the package I’ll get some serious use out of these. Once opened I have them separated in the plastic and in a ziplock to prevent them from drying out.If you do regular guitar maintenance definitely get one and add it to your guitar cleaning routine.Be careful and sure to use gloves or some other means of preventing skin irritation. Read the label!

Worked great

Bought my first one back in 1975 and using them every now. And then ever since they work well.

Absolutely amazing. It works on all metal services that I needed it for. Gold, silver and copper

I have used these for many years. I have used them on high carbon swords, fine gold and silver, brass and bronze of all mixed content. These absolutely work extremely well and with much less work than any other product I have tried (and I have tried a lot). My fear thru the years is that they may someday discontinue them. I have never used them on anything but metals. The following is the best practice I have found and its easy. First, the cloth turns black. Don't worry just keep using it even the black parts. As soon as it turns black it's actually working better. Just rub around on whatever you're cleaning with the same part of the cloth or use more of it if you think you should. It, your hands and the thing to be cleaned will turn black(ish). When every part has been rubbed down use a towel (one you don't much care about much) and wipe it all off. Do it aging the same way but start with a clean part of the cloth. Wipe it down again. Take the object that you just polished to a sink and wash it and your hands off at the same time with soap and water. At this point you will see it really shine. Then use another towel (this time any because it's clean) to wipe it off. You will have a well polished item with no tarnish and completely shiny! I did a very old incense burn from a Orthodox Church that had not been cleaned in decades. That one took a few hours with years of tarnish and coal and incense caked all over it. When I took it back the Priest took me aside and politely asked if I found the same burner new and just purchased it! He actually saw it as a completely new one. And it for sure looked new. If you have any old metal and use this product as I have stated (depending on the lack of care you may have to repeat the steps) you will have a brand new, shiny to the point where it's hard to look directly at result.

Works better on polishing frets than any other product in my kit & I've bought/tried a ton of different products/supplies. After leveling & crowning, this is all i need.

The cloth came dry and wasn't very effective at removing tarnish from brass. With some elbow grease I was able to get a little off, but I compared it to an old t-shirt with nothing on it and found that to be equally effective. In the picture, if you look carefully, you see the brass is a tiny bit shinier on some parts of the front ring of the device. I was hoping to get the whole thing shiny, but gave up at this point. I eventually got the item the way I wanted by applying Brasso with a kitchen sponge.

Perfect for minir rust spots, nivkle plated items
