Hey everyone. I'm refinishing the stock for a Glenfield (Marlin) Model 60 that I found at the pawn shop a little while back. I got the old finish off and it's down to the bare wood. Unfortunately, there seems to be some sort of grime soaked into the pores of the wood that I'm having a bit of trouble getting rid of.
I've tried sanding and wetting the wood to raise the grain. But it doesn't seem to be helping much. Nor does rubbing it with mineral spirits. Is there any sort of soap I could try that might get this stuff out? I'm a woodworking noob, so any and all advice is appreciated.
