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?

Hi Mike,

I' haven’t read the article in question. But vinegar and talcum powder can be use to degrease brass and copper surfaces. It will remove the grease from finger prints and is mostly effective when rubbed and then washed in water...

Basically the vinegar is a very mild acid and is used to etch the PE to create 'tooth' for the paint to adhere to. It can be also used to clean oxidised PE for the glueing process.
White vinegar is the one to use.
