Ammonia, Ill check it out, but that smell! Kerosene smells properly industrial to me, simple green is, at least to me, a pleasant nostalgic smell Ive never identified, mineral spirits and turpentine, meh. I know smell isnt a practical indicator, but it will just take some getting used to!
Ive got three important projects, but a goodly number of old '03 stocks (S, Scant and C of '03 and A3 configuration) that needs work, so I may have to try a number of these methods. I refer not to apply heat, but all of these suggestions sound worth a test. It should ben noted that the stocks that need cleaning have simply been used, oiled, greased, dragged in dirt, sweat upon, etc. for decades. These are battle hardened military stocks and for the most part made of a decent grade of Walnut.
I thank you all for your input
