Have fun with the Cosmo.
While mentioning bolts - the most important place to clean in any SKS is the firing pin channel in the bolt - I recommend driving out the firing pin retainer pin in the bolt and just soaking the bolt in mineral spirits. Auto brake cleaner works well for the firing pin channel and other tight spaces as well like the sear rails. I would probably not use the brake cleaner on the gas block though - I am not sure if I would want that stuff in my bore, maybe just use some mineral spirits on a bore brush and maybe some aerosol CLP in there also.
The one (and only) slam fire I ever had was from placinga cartridge in the chamber and letting the bolt drop.
Fortunately it this happened at the range and the 4 rules were being obeyed.
I bought mine specifically to have to beat up. I don't care about the scratch mark. And by the way, if you install a Tech-Sight, it replaces that pin.
Oven cleaner will strip the finish, I would not recommend it for just removing the cosmo. I used it on a Mosin Nagant 91/30 to strip the finish before refinishing.
I used an old tooth brush, Hoppes #9 and a rag to wipe clean the cosmoline from my two SKS's and Mosin Nagant. Worked great but required a second cleaning in a couple spots on the Mosin Nagant. Most any gun cleaner should work.
IMHO boiling water works best and it heats up the metal and evaporates very quickly as well. Take the stock off and put all teh small parts in a pan of water and put them on the grill outside. Boil more water and pour it down the barrel. Done.
Seriously, throw a cheap pair of work gloves in the case with the gun when you go to the range, that stuff is like getting hot oil on your skin, probably because it is hot oil on your skin.
as to the scratch yeah it happens, a real bummer on a nice looking SKS especially but it seems that on my Yugo it is unavoidable.
hope that helps
BTW when I cleaned my Yugo out it took a can of mineral spirits, three cans of brake cleaner, 3 hours total in the oven for the wood parts, and about 5 hours total from initial teardown, to oiling, to putting it in my safe.
