Clean Bolt
« on: October 23, 2010, 01:48:49 AM »
I've had two M48 Yugoslavian 98 mausers and now a M77 Ruger mkII in 280 that I really like.  The bolts on these 3 seem to be in the raw because they accumulate a grunge smear after only a few working of the actions.  I have other bolt actions of various ages but these three are the only ones that acumulate that black dirty oil.  Is there a treatment for the bolts to keep them in the white and more shiny?

I guess first I would try to identifie the source of this "black dirty oil". You my need to flucsh the firing pin spring and its channel out with some good solvent.

It's more of just metal on metal with clean oil turning dark right away from little action motion.

You need to clean everything squeeky clean. The dirt can be coming out of the pores of the metal.  Take the bolt apart too. So a good soaking(bolt) in kerosene or diesel fuel may help get the grunge out.  Then i would use a hoppes solvent or a G.I. Rifle Bore cleaner for its final wash and to get the kero/diesel smell off it them too. Have you taken the receiver out of the stock?  If you can you may want to soak the receiver too.

Lately i been washing everything down with rubbing alcohol too.  I haven't ruined any finishes on the wood yet but it may be possible down the road with some stock finishes i'm not sure yet. But it seems to make the oils rise.  Using murphy's wood soap will do it too on wood.  I have used that straight out of the bottle so its strong and let it sit on the wood for a few minutes.  You can actually see the oils leaving the wood.  Then i wipe it off with a dry cloth and repeat until the wood is clean too.  My point is if the metal is seeping oil or making your new oil turn black it can also come from the stock bleeding too.  Sorry that i go off sometimes without explaining myself.  If i do just ask what i mean.


(stock info) But i do notice some stocks are so oily they continue to bleed no matter how i wash them down.  I have one sitting here near me that bleeding so bad i get oily hands everyday when i touch it its completely soaked.

+1  to what 1911crazy says.

Cosmoline is the most likely culprit. Deisel, sewing machine oil ( I don't know where it went honey honest), 3 in 1 oil and transmission fluid are a few of the solvents I have used. If you are able to dis-assemble and reassmble you can also scrub the parts with solvent and a small parts brush. One of the wofe's surplus rifles required that cleaning to cure bolt problems.

Just my 2¢
