hi , i bought some mineral spirit from Canadian tire , disassembled my sks , kept trigger as is , pulled the rest apart including bolt housing , firing pin ,pin retainer etc , gave the whole thing a general wipe then got a container long enough and soaked all metal parts including the barrel, left soaking for 24 hours .. then used a tooth brush and gave it a good cleaning with fresh batch of mineral spirit .. dry it out then used hopes 9 after.. just make sure you are in well ventilated area
