What can you use to clean cosmoline off of and out of a milsup rifle? Back in the day, we used gasoline but I think that's frowned on nowadays.

MEK will do it as will a strong mix of Simple Green. For a final degrease, I boil the pieces/parts in washing soda.

Brake Cleaner works real good. Buy the good stuff not the this or that free, better for you and the environment crap.

Cosmoline melts at a reasonably low temp. I've been using a hand held steamer to remove it from milsurp metal for years. A cheap and environmentally safe way to remove it. I use an Ovglove to hold the barrel, as it will get quite hot. Getting it our of the wood can be much more problematic, depending on how long it has been on the wood and how much has soaked into the stock.

I take mine to work in pieces and use 50# steam Big Grin

I have to be discreet with the barrels. If I didn't have access to a steam system, I don't know what I would do.

I think the melting point of cosmoline is about 150 F.
I saw an article using a DIY garbage can and a couple of lightbulbs .Hot enough to melt it.

MEK is a VERY efficient solvent but but unless you want to dissolve your liver do it outside with a large fan.

Paint thinner works well, lacquer thinner much better. I have found the environmentally friendly products to be far less effective than the old standbys. Like gasoline. Once you get most of it out of the wood, you can use TSP to get it cleaner, and lighter in color. I soak them for 20 minutes at a time. Turns grease to soap and leaches it out of the wood.

As a cadet, the guys on punishment tours got to clean Springfields in split oil drums filled with kerosene then the rifles were put in the locker rooms shower with nearly boiling water.
While the rifles were still hot they were wiped down then oiled. There were 500 or 600 rifles so the guys who could not work within the system learned an awful lot about Springfields.

Inside a closed car on a sunny day in NM will make it run out of a rifle like water - just make sure the rifle's resting on something cosmo' proof & that you meant to do it.... Whistling

Get a cheep plastic gun case. Pull the foam out. Fill one side of the case with cat litter.
Put the offending stock in the case cover it with the cat litter. Close the case.
Put in hot car or set on a hot roof. Turn every day or so.
The primordial gun ooze, ie cosmoline, will leach out in a few days.
