I got an sks that was dunked in cosmoline somewhere in Yugoslavia.  Its a 59 non issue I believe.  
I took it completely apart, turned on my grill to about 100 degrees and put all the wood on tin foil and grilled it in there for 4 hours.  The cosmoline melted out of the stock.  Then I sanded it and stained it, lacquered it, now it looks beautiful.
Would anyone like to purchase a Dan Wesson .44 mag, six inch ported barrel, stainless steel?
FFL transfers welcome.
