Awhile back I read somewhere that some people soak PE frets in vinegar prior to using. My question is, what exactly does the vinegar do and for how long should the frets be soaked in it. I am assuming that the vinegar used is the white variety. Thank you in advance.
I'm pretty sure vinegar oxidizes the surface so that CA/paint has better adhesion. I can't help with how long but perhaps you can stick an unused bit of fret in some for a few minutes?
