I'm guessing this was Squeeze's "stock fix" some time ago ... well done, Squeeze. 
Nah... I've tried the oven cleaner trick, bags in the sun, mineral spirits and all that. All of them are too much work with not enough results (read: I'm lazy). The best method I've found for the stocks (and everything else) is take the gun apart completely, throw all the pieces into the dishwasher on pots & pans and heated dry. Granted, I wouldn't do this if you have a stock with any special cartouches or one you don't want to sand in any way.
Once all the parts are done in the dishwasher, set the stock pieces aside to dry a bit more and take a CLP-dampened rag and rub down all the metal (there will be some flash rust from the drying cycle, but it will wipe away with CLP).
When the stock is completely dry, take 00 steel wool and smooth out all the raised grain. Follow it up with 0000. Once you are satisfied with the smoothness, go over it with a tack rag to get rid of the dust. After that, take Boiled Linseed Oil (or Tung Oil...
not Tung Oil Finish) and put a small puddle in your hand and let it warm up a bit. Then, with your hand, rub the oil into the wood. Take you time and get all the nooks and crannies. Once you've got a good coat, set it aside to dry overnight.
I let it dry overnight, then assemble the gun. After a couple days, when the oil is good and soaked in (the stock will appear somewhat dry looking), take some Howard's Feed n' Wax and rub it in to the wood. I don't bother to disassemble the rifle again, as it's just beeswax, orange oil, and carnuba, and it wipes right off the metal if you get it on. Rub a good coat in by hand and let it sit for a day or so. After that, you should be good to go.
Depending on the environment you store it in, you may need to occasionally reapply some Feed n' Wax to keep the wood hydrated, but this is a good idea on any unsealed wood finish.
I've done this procedure on all 6 Garands I've purchased through CMP, one Carbine, a K98k, a Romak, and an Yugo M70. Thus far, it's worked well for me and I've been happy with the results. Of course I don't have to worry about a nagging wife or mother telling me what I can/can't put in the dishwasher. YMMV.
