Hi all. I'm doing some work on a vintage Zim-gar solid body electric which was my grandfathers and needs some major tlc! I've taken the bridge and saddle etc off. They are dirty and oxidized. Any tips for cleaning them? I know you can use a diet coke bath and that helps. However, I've also found directions for making your own reverse oxidation bath with a nine volt battery, stripped wires, and salt water. The electric charge will be more effective according to some research I've been doing. Also, I need to re glue the nut back on as it shifted half an inch off. What kind of glue should I use and how should I apply it? Any tips would be great. After taking all the parts off that easily come off, I polished the whole guitar and I just cleaned the fretboard and have lemon oil soaking in right now. I think the neck is warped but I'm sort of doing this just to do it. Thanks, Cameron.
