I use amix of NAPA degreaser with a little kerosine, does a great job on cleaning cosmoline off all my
Mosins and the SKS that I got that was loaded with it .
Also need a good compresser to blow dry the parts off .
'Love the stuff...but it's water based and I don't want any chance of water left behind...even after blowing out with air compressor, etc. It's a great cleaner though!
