An old post but I thought I'd add my new experience with Murphys Oil used to clean up furniture on old guns.
Picture taken just after I walked out of the gunshop.
About a month ago I bought a W. Richards 12 gauge side lever. (Ok, I know it's not a Westley Richards but it was complete, solid, locked up tight on face, matching numbers and looks to me like Birmingham proof marks. And the price was right.)
I haven't done anything with it but today I took it over to the gun club as a show and tell. One old curmudgeon told me to use Murphys Oil to clean the crud off the wood. I tried it this afternoon and was amazed at the results. I used burlap cloth on the thick spots, a fiber bristle brush on checkering and scrubbed hard with old terrycloth rag.
