A common topic and problem. We've all used acetone and other less volatile solvents. Many of us have used whiting and mild heat. (I still like that one for the more important stocks.) Oven cleaner is quick but brutally costic and leaves surface fibers coarse which mandates heavier sanding than may be desirable.
But my current project is several abused model 12's.
I have another solution, at least potentially. Amonia. It is a wonderful solvent for all types of oils, grease and dirt. The things we encounter in old, abused guns. Amonia is cheap, readily available and not volatile--ie, it might not evaporate within a couple of hours.
I can't think of any reason not to try it. Please let me know if there are any. Otherwise, I'll report back in a week or two. Gil
