While I wait to acquire an appropriate stock set for my late 1940 Garand, I decided to clean the muck off of the one that it's wearing now, a visibly marked RIA FK cartouche on a wartime Springfield stock. Using a 50/50 mix of mineral spirits and teak oil, 0000 steel wool, and a towel, I managed to uncover what was hiding beneath the gunk. This SA NFR and ordnance wheel are now somewhat visible, no longer hidden beneath. I'm very pleased with how well this stock cleaned up.
