Hello there, back again with another review for you! This time, we will be looking at a beautiful product I recently discovered: Göldo fret polishing rubber! As I always do, I will give you some quick information about the Göldo company and also provide you with a fret polishing rubber review video in action!

About Göldo
For those who have never heard of the Göldo company, it’s a German company well known for its Göldo-branded guitar parts and many other high-end imported brands.
Their own Göldo-branded parts are very affordable and offer high value. So if you are looking for any guitar parts such as guitar pickups, guitar pickguards, guitar/bass pots, fret wires, guitar/bass bridges, switches, guitar nuts, tremolo systems, as well as many instrument maintenance & care products, Göldo should be your first choice.

As far as I understand and have tried to reflect in the beginning, I think they also represent many imported brands in the guitar parts segment. I have recently purchased a Göldo fret polishing rubber and couldn’t really wait to try it on my Fender American Standard Stratocaster! I bought a bunch of stuff from Thomann, and my order arrived in a huge box. 
Unfortunately, Thomann arranged the packing for bigger items, but didn’t put these small accessories and products into a zip bag. My package was also opened and checked for damage control by the Slovak parcel company. Everything seemed to be OK except the missing Göldo fret polishing rubber! I reported this to Thomann as well as the UPS company. As expected, Thomann quickly reacted and already sent me a new item at no cost. And also, as expected, UPS never cared!

Review
When I opened the package, I noticed it was Hosco-branded fret polishing rubber and did a quick research. And yes, these are actually made in Japan by the Hosco brand but are sold under the Göldo brand in Thomann. So don’t be confused when you receive your parcel! It’s an authentic, high-quality product. As stated in many user reviews, my first impression was that I just purchased a pair of rubbers. 🙂

And it indeed feels like a rubbery material. Unfortunately, I couldn’t test it right away. But then I broke my high E string on my Fender USA Standard Stratocaster and thought this could be the best time to try Göldo/Hosco fret polishing rubbers!
Before Göldo/Hosco fret polishing rubbers, I had also tried Dunlop Micro Fine Guitar Polish 5410, and I also liked the result. However, Dunlop Micro Fine is not so durable, and after a couple of polishing sessions, you would run out of the polishing surface and buy another one. So I wanted to give Göldo/Hosco fret polishing rubbers a chance and even recorded a short video showing you this in action. 
How to Use Göldo/Hosco Fret Polishing Rubbers?
It’s pretty easy, as you can guess. All you need to apply some firm pressure while polishing your frets with this polishing rubber. As you will see in the video, I didn’t really use any fret and fretboard savers such as Göldo WS045 Fretboard Guard, Rockbag Fingerboard Saver Set, or any masking tape; however, I was being careful not to scratch the fretboard as well. Having said that, I do recommend you get a fretboard saver or at least use some masking tape. I don’t reckon I will use these without protecting unfinished rosewood or ebony fingerboard-equipped guitars. 
Here’s a photo I took right after I had finished polishing the frets. As you can see, it leaves a lot of rubber dust/particles, just like rubber does when you erase something on the paper (but with finer particles). You can also easily see how much they shine already. Note that I didn’t really spend too much time on this polishing session and only adjusted the photo’s brightness so you can see it better.
Before, the frets looked yellowish, and now they look really shiny and bright. Before I provide you with a short video, I would also like to add more photos. So if you don’t want to watch it, you can quickly have a look at the before and after photos. Here’s a photo before I polished these frets with Göldo/Hosco fret polishing rubbers.
And here’s a photo after I polished these frets with Göldo/Hosco fret polishing rubbers and cleaned the rubber dust.
It definitely works, and I can’t wait to try this on my other guitars! The only problem is that it leaves some residue, just like what you would have with regular rubbers/erasers, but with smaller particles. 
You had better be prepared for a good clean-up! Fortunately, cleaning a gloss maple fingerboard is pretty easy. You can just use regular guitar polish products. However, I am not sure how this should be done with unfinished ebony or rosewood fingerboards. Once I have tried this on my other guitars, I will surely update this part of the content. 🙂
Göldo/Hosco Fret Polishing Rubber Test Video
As you can see in the video, Göldo’s polishing rubber turns grey/black immediately when used. It’s an indication of a successful fraction for sure and is nothing to be worried about. But you may complain about the residue it leaves behind. Although it may be perceived as an overpriced product, I must tell you that it’s definitely not! You can actually cut these grey layers with a razor blade and still use it. Considering you have a pair of these rubbers and you only use these per string change makes these are extremely cheap. I believe these will last a lifetime, and one shouldn’t feel the need to keep buying these again.
Overall, I’m 100% satisfied with Göldo/Hosco fret polishing rubber and totally recommend you try these out. It’s one of the most practical and non-destructive guitar fret polishing systems ever! The only thing you need to do is polish your frets with these and clean up the rubber dust; that’s it.
Pricing & Availability
As explained above, you may have either the Göldo or Hosco-branded version of the fret polishing rubbers when ordered from Thomann. Currently, they are still under the Göldo brand on Thomann, and there’s no indication of Hosco on the actual product photos. But as I experienced, you may have the Hosco ones, which are all made in Japan.
I bought them from Thomann back in 2021 for €13.90, and so far, the price increase has been pretty reasonable. Currently, these sell for €14.90 (It may be different based on your location).
Mind you, there are also fret rubbers that come with different numbers. The one we are talking about here is the #1000 that indicates a fine, smooth polishing. There are also lower-numbered ones, just like sandpapers. So, you may want to get these in case you want to approach your frets in a more structured way (going from low numbers to high numbers while polishing).
