So after a few years of owning a yugo and albanian sks, I decided that today would be the day I removed the cosmoline from them. No problem I thought. I bought some brake cleaner and went at it. My albanian disassembled fairly easily, the trigger was somewhat of a pain to remove, I needed a hammer and a punch. But the fucking stock is stuck to the reciever, worse the magazine will not come out like a good boy, its just stuck there. I tried pulling, prying, hammering it out, but it refuses to move. So I cleaned what I could sort of and left it for another day. The yugo came apart fairly easily, but there is only 74 thousand times more cosmoline on it, and its dried to the stock. I gave it a half assed effort and also left it for another day. Removing this crap is hard work. I wish there was an easier way.
