    WD-40 and nylon shop brushes or toothbrushes, and lots of paper towels.

    Or you could dip the whole gun into boiling water.

    Whichever you do, make sure to take the stock off.

    Hair dryer and a rag work .

    heat it and once it starts seeping out of the wood(put the blow dryer down) then hit it with some CLP or WD40 and wipe it off.

    I got a Yugo SKS that was soaked in 2/3 the world's supply of cosmoline. Every time I took it shooting and it got warm, the stock would sweat melted cosmoline.

    SO...... what I did was to take the stock off the rifle and wrap it in almost a full roll of paper towels, then stick it in the oven at 150 to 175 degrees F. for an hour or so.

    Then discard the wet paper towel and wipe off the still warm stock with dry ones as much as possible.

    I did that THREE TIMES before all the crap came out... but at least now I can shoot the rifle without getting cosmoline all over myself.

    Warning: Wifey will NOT be pleased! But it's better to beg forgiveness than ask for permission (which you will NOT get - believe me!)

    As far as the metal parts... just take the rifle apart and clean it. Gasoline works GREAT as a solvent, but obviously it's terribly dangerous (toxic AND flammable). Coleman fuel (naptha) also is a good solvent and much less dangerous (but still flammable).

    Or, if you're a green-weenie you can use one of those "bio friendly" cleaners like Simple Green (which actually does work quite well).

    Be sure to thoroughly lubricate the steel in your rifle after cleaning it though.. degreased metal rusts fast.

    Are you serious? That would make the wood swell and splinter!

    the answer, and the common thread in all of the replys: heat.

    im guessing that would only work on the wood stock or would it also work on the rest of the gun as well

    I read it as "take the stock off" (before boiling it). I would never have thought to boil STEEL parts!

    Heat / absorb / repeat as necessary - for the wood.

    For the steel, take it all apart and clean each part in a good solvent, re-lube and reassemble.

    I'm serious, but I'm not sure you are.

    Who the fuck would boil wood?

    Mineral spirits shouldn't effect the shellac that the Russians used. A lot of times the shellac flakes off and once you remove the cosmolene it flakes more. Besides mineral spirits I've had good luck with Purple Power (sold here at Advance Auto Parts and I believe Walmart). After the amin cleaning I use a paint stripping heat gun on the low setting to heat up deep patches of cosmolene and bring it to the surface where I can wipe if off with mineral spirits on a rag. You can also wrap the rifle and or stock in black trash bags and put it in the trunk of your car parked in the sun. After a few hours pull it out, wipe it down and repeat.
