Default cosmoline in bolt?

Bought a russian sks a few weeks ago, and reading some of the forums makes me wonder if i didnt completely get all the cosmoline out. I just field stripped it and let all the pieces soak, hoppes #9 with q-tips afterwards. Would cosmoline soak into the bolt? I'm pretty picky when it comes to cleanliness, especially with my rifles. I have never disassembled a bolt before so I have no idea where to begin! Step by steps and pictures would be awesome! Thanks in advance!

Absolutely possible and usually the issue with light strikes. I've seen nagants when the firing pin would just slowly creep forward because they were so caked with cosmoline.
YouTube should have a step by step video.

Well then I should probably get on that! Soaking it in hot water with dawns soap is ok right? Or should i use an actually cleaner like hoppes? Is it pretty easy to assemble them afterwards?

Mineral spirits will work well on breaking down the cosmoline. Teh Russians used oil, bees wax, and some other grease to make up their cosmoline. often the wax is what doesn't break down with other degreasers.

http://yooperj.com/SKS-25.htm see the bit on "slamfires". Does your Russian have the older, better, spring-loaded firing pin?

Thanks for the link by the way, that'll keep me more self conscious with keeping my bolt clean and the hazards of neglecting to do so!

I'm also a big fan of a short soak/scrub in mineral spirits.
I usually use mineral spirits as a first step for all my routine gun cleaning as well.
It helps keep my Hoppes pretty clean too...

Another way to attack that stuff is a hot ultrasonic tub.
