Well, I began tru-oiling my warmoth neck today, and after my first coat I lightly buffed it with 000 steel wool, then I gave it a quick wipe with naptha. once I finished I noticed some of the frets looked like they had bled into the wood. The only thing I can think of, is there may have been a little steel wool left on the board when I wiped with naptha, and it dyed a little into the wood . Here is a picture of what it looks like. Is there any way I can use a small application of bleach to remove this? thanks in advance for your help.
