I hit mine with Oven Cleaner, then boiling water, then Oven Cleaner, soaked for 20 minutes, then boiling water. Now they are on the extra hot "pots and pans" cycle in the dishwasher. 94 minutes of hellfire and detergenty goodness.
I will sand and Tung oil them tommorrow.
I will replace one with either walnut or synthetic if I build it up as an M-21 configuration. The other one is getting liberally oiled and vacuum sealed for either a rainy day or to trade for a Remington 700 at some point in the future.
all the steel was heavily oiled, and I scrubbed the hell out of it with detergent and boiling water in the sink. Lightly oiled with Hoppes, and they are looking pretty good.
Overall, I am pleased for the price. Although the jury is still out till I see what happens with these stocks. If they don't come out clean and at least serviceable, I am going to be pissed.
