Apologies if this has been covered in another thread...I didn't spend more than 5-10 minutes looking and might have missed it. Anyway, I have an old, very nice Schecter neck that was put on a guitar and used without ever finishing it. It's probably 20-25 years old. Perfectly true, no twisting, no issues, plays great. That said, I'm going to finish it with Tru-Oil, but first I'm wondering if anyone can suggest a wayt to clean it up a bit. It has lots of dirty black staining on the fingerboartd and on the back of the neck from being played with no finish. Sanding has helped about 25%, and I don't want to sand more than than I need to prepare for finishing. Any other tricks to cleaning it up you would care to share? Thanks!
