How do I get the Cosmoline out of my Mosins wood stock?
#1
I got my Mosin yesterday. It was $150 out the door with most of the accessories, a 20 round box of Silver Bear and the associated fees related with the transfer. Anyway I am thrilled with the rifle: Built in 1938, round receiver, metal and furniture in excellent shape. However the rifle has been soaked in Cosmoline to the point that it melts off onto my hand when I handle it. I have been reading online on removing Cosmo from the rifle. For the metal parts it's widely accepted that Simply Green and hot water will take care of the Cosmo followed by a coating of CLP Break Free will protect the parts from rust. However getting the Cosmoline out of the wood stock gets into a heated debate it seems. I have read so many different opinions and counter opinions on the internet my eyes are about to bleed.

Some say use heat. Not a problem but I won't put the stock in my oven, I don't mind using a hair drier or heat gun but it seems extremely time consuming and the other methods of using heat are too involved or the things required aren't available to me (Hard to use my attic when it's in the 20's). I really want to avoid using harsh chemicals on the stock because I want to maintain the original Russian shellac/finish. I am considering letting some Simple Green sit on the stock and then wiping it down with some hot water/rags (Not going to submerge the stock in water for obvious reasons) but I have concerns about the effectiveness of this method. Will that little bit of water swell the stock and is the Simple Green powerful enough to pull the Cosmoline out of the stock?

Just to let you guys know what I have available as far as cleaning products are concerned:

-Engine Degreaser
-Simple Green (Diluted I believe)
-Break Free CLP
-Hoppes oil and cleaner

Thoughts? Also do you guys have a disassembly guide for beginners? Sadly, I don't have that tool used for breaking down a Mosin so hopefully regular screwdrivers won't strip the screws. I want to get this project underway today. Thanks. Here are two photo's to give you an idea how soaked the stock is in Cosmo:

I used a hair dryer and worked at it when I could. Another method is to leave it out in the sun. Unfortunately this really only works in the summertime...

Can you fit it in your dishwasher? Seriously. If you can, wash it (using no detergent) and then refinish it with linseed oil or tung oil. A lot of guys refinish M1 garands this way; I've done one myself.

How long did the hair drier method take? Huh

I was thinking of doing this but that won't fly in my household.... Confused

I'm here to make you feel better about your rifle that is "caked" (lol) in Cosmoline...

Good luck.

I really can't see Simple Green, or any other non-toxic method working all that well, but I've never tried it.
You don't want to know how I did mine.

hair dryer took me a couple of days, but i was working at it off and on. Just held it in one spot to get it hot, wiped off anything that came off, moved to another spot.

I'm sure there is still some in the stock, but I don't notice it. The important part was getting it off of the metal.

Just an update. I have the gun disassembled, threw several pots of boiling water on and threw them, soaked with Simple Green, cleaned with a toothbrush and ran more boiling water over them. The metal parts dried and I coated them with CLP. Two concerns right now, I got a good look at the inside of the barrel and it looks bad. It looks like a sewer pipe so I shot some CLP down it and will do a bore brushing soon. Second the stock, I am using the hair drier method and I am only having some success. I am still working on the little strip of wood on top of the barrel and after an hour it looks like I made no progress. I tried rubbing a little CLP on the wood but it didn't really do much. I am thinking of trying Simple Green. Here are some photo's:

Metal parts soaking in CLP, some bluing is missing from the magazine I noticed:

The stock, nothing to really see at this point:

What I got off the metal parts after the washing:

I took a second look down the barrel 30 minutes after spraying it down with CLP and it looks much better, what I think I saw was chunks of cosmoline.

Two methods I have used, both worked.

Oven cleaner, and refinished.

Worked well, but it USA pain.

Also, stuffing it into a garbage bag with kitty litter.

Another option is to run a few dozen volleys through. Cosmo will drip from places you never knew existed.

Save the Cosmo if you can. Makes great cologne Wink
