Dunlop Micro Fine Guitar Polish 5410

These things are basically really fine grit sanding cloth. 8000 grit in fact. So you'd have to sand the frets with something more coarse to start with if they are corroded.
I use some wire wool and a fretboard protector first and then the polishing cloth.
Probably better for keeping your frets nice rather than making horrible looking frets nice again.

Från smutsiga och sträva till skinande och sköna greppband igen! Snabbt och enkelt, särskilt tillsammans med vilken billig "fretboard guard"/"fingerboard saver" som helst till (i rätt storlek).
Ska man polera många gitarrer eller ofta kan det vara värt att tänka på att dukarna (2 st) är rätt små och "används upp" relativt snabbt (beror också på hur mycket jobb man gjort på banden innan med t.ex. "polishing rubber").

My frets were very dull and grimey, now they're shining!
One cloth is enough for a whole fretboard, you can clean the cloth and use it again but I guess they won't be as effective as the first use.

This is a very fine polishing cloth. I use it as the final step when restoring/polishing my frets and it works great. You can use the same cloth multiple times without problems.

Ju mer du polerar, desto lenare och blankare blir metallbanden.
Vilket i sin tur förenklar bends.

Bra för underhåll !

This was abosluty waste of money, it didn't do what it supposed to do, and trust me, I did it the right way. After watching a ton of videos online, I knew how to do it the right. I used it on my classical guitar. Sorry, but I'm just being honest, useless.
