Start by using the FRINE fret polishing kit, which will not only facilitate bending and vibrato but also extend the life of your strings. The revolutionary FRINE Fret Polish features micro-fine compounds that allow you to safely and quickly polish your frets, removing oxidation, dirt, and accumulated sweat.

The second step is to use F-ONE, designed using a complex blend of the finest ultra-refined lubricants for cleaning, conditioning, and protecting your unfinished fingerboard. 100% pure, without any lemon oil extracts, wax, petroleum distillates, silicone, or water, it makes your fingerboard look like new and leaves a smooth feel for playing.
