Mooreshawnm- I've cleaned up a few dozen or so milsurps for my own, and I found the best way to clean the stocks after an initial wipe down with mineral spirits, is to lay them on the top rack of an oven set on bake at about 200* or the warm setting. Wrap foil around the bottom rack to catch the dripping cosmo. Take it out every 5 minutes or so and wipe it down with spirits. Keep repeating until no more cosmo sweats out. It may not fit in the oven without the door being cracked open, so flip it like you would anything else you cook. I've found this to be the best way to get all the cosmo out. Now keep in mind, it works best for bachelors, as it will smell like a Cummins diesel idled in your kitchen for a few hours. Also, make sure to keep an eye on the stock while it's baking. It will get hot.
Now, I have tried the dishwasher technique with excellent results on junker stocks, but do it at your own risk. I've heard reports of warped stocks and all kinds of wood-mayhem. The combination of steam, a degreasing agent, and the heat does wonders for dents and grease, but it will also raise the grain and the stamped cartouches. But I have created beauties from worthless crap this way.
this is a mint, never-fired, probably never-issued M1..so it has high collector value...
high collector value..
a friend of mine puts the stock out in the Arizona sun for a couple of hours and than uses Easy off oven cleaner lets it sit for a half hour than presure wash with hot water
I have used the dishwasher method on a number of M1 stocks with no ill effects, to even valuable cartouched stocks! I usually hit the dents with a home type steam generator first, then put the stock in the dishwasher on the "pot & pan" cycle with a full load of dishwashing compound, "heated dry" turned off.
Now, let me say that this method will remove all the cosmo, grease, oil, dirt, and the original blo/tung oil finish. It leaves bare wood like the armory started with 60+ years ago. I use stain and tung oil finish to put them back in service.
I've never had a cartouche lifted, and have another one with an "NFR" cartouche that I'm going to dishwasher tomorrow.
If you want to preserve much of the blo/tung oil crosslinked, polymerized, darkened finish, don't use the dishwasher. If you want a clean slate, it works well and the naysayers just haven't tried it (I still haven't found one who did it properly who said it ruined his stock!).
