View Full Version : Cleaning cosmoline off mil surplus rifle

I just picked up a Turk Mosin Nagant that has been packed in cosmoline. My understanding is to use kerosine and a brush to get rid of the gunk. Any tips on this procedure?

Remove the wood and soak the parts in the Kerosene. A little heat applied to the parts first would help. Don't soak and then heat.

The Turks used Mosins? Did they buy them or just use captured Russian guns?

Anyway, I found that hot water and Simple Green gets most of the cosmoline off the metal. A spray can of brake cleaner gets the rest of it. Don't forget to dismantle the bolt to get all the cosmoline out of there.

Getting the cosmoline out of the wood is the tough part. I haven't found a good method or product for that yet.

I bought a product called "Purple Power" from an auto parts store. It is probably the same thing as Simple Green. I take the guns apart, put them in the bathtub, fill a spray bottle with purple power and spray down everything. I leave it sit for like a half hour. Then spray it again and scrub with a toothbrush. I then hose it off and let it dry. If it didn't get it all, I do it again. At that point you usually have to give the stock a few good coats of linseed oil.

in the stock cleaning section! But the Purple power is s good idea. One trick is to boil the bolt in water, then de-grease. It makes dissassembly easier and can even substitute for it if you have a particularly clean bolt.
