Easy Cosmoline Removal: Cleaning a Mosin Nagant

[@intoweapons]

Glad the mineral spirits worked for you! Thanks for watching :)

[@floydteter4323]

Did the mineral spirits thing. Left all metal parts in mineral spirits - 3 rounds of 30 minutes per, with a rinse and dry after each soak. Started to put the thing back together and ran into the sticky bolt issue (unloaded). Broke down the bolt and let it sit in boiling water for 15 minutes. The grease that came up in the boiling water was not to be believed...blobs of brown gunk everywhere. Sticky bolt problem seems to be resolved now (we'll see for sure when I fire it). Boil your metal.

[@intoweapons]

I am glad you found it useful, good luck with the Mosin cleaning! Thanks for watching.

[@intoweapons]

Good luck! Really can be a pain in the ass to get that stuff off... The process in my video worked pretty well for me, so hopefully you have some luck with it. thx for watching!

[@intoweapons]

I let everything sit for about 4-5 hours... Thanks for watching!

[@docwilkey]

Good info. I have done many military firearms myself over the last 40 years. I found that soaking in kerosene works great. It's cheaper and evaporates on its own.

[@intoweapons]

I rinsed everything off in the kitchen sink. I used a can of air and a hair blower (high heat) to try and dry the parts as best as possible. I then put everything into the oven at a reasonably low temperature for about an hour to evaporate the rest of the water. Thanks for watching!

[@vee_emm_jay_ess]

That PVC pipe is an awesome idea!

[@intoweapons]

thanks! It works well, unless the trigger guard is too big to allow the receiver to fully dip - my AK's have that issue :)

[@vee_emm_jay_ess]

LOL I just noticed we have similar profile pics.

[@intoweapons]

Yes, all accessories were coverd as well. the oil can was the most difficult to get clean. i covered all accessories heavy with hoppe's #9 gun lube to protect from corrosion in storage and sealed in a bag. thanks for watching!

[@intoweapons]

I don't think that temp should be an issue for the stocks... I am actually heading to Vegas today for vacation! Thanks for watching and the sub!

[@1anthonybrowning]

A wallpaper gluing tray works good, cost next to nothing and is available at Walmart. I had no noticable degradation to the tray while soaking the parts in mineral spirits. It is long enough for a M44 barrelled receiver to sit in there diagonally and all the parts to set in the tray also. I did use PVC pipe for the 91/30. Works good.

[@b456789]

Mineral spirits worked good for me. Soaked everything but the barrel. Used Hoppe's #9 with .30 cal / 8 mm brush and Rem Oil. Cosmoline was more on tools than everything else. Barrel definitely needed cleaning though. Used bucket to soak parts, rinsed, baked at 200 degrees for short time then sprayed with Rem Oil. Thanks

[@intoweapons]

In my opinion, boiling water only lasts as long as the water is hot. I prefer mineral spirits over boiling water, but that is just personal preference. thanks for watching!

[@intoweapons]

I did not mix the mineral spirits with anything and I did perform a bore cleaning after this process was complete.

[@apex831]

I actually used Ana aquarium heater in my tank with dove soap, put hot water in and got to 135 dg F, soaked for 2 hrs, rinse and repeat. Then did the mineral spirit with no heat. As a final cleaner. Then just wiped down as the mineral spirit just Evaps.

[@intoweapons]

I was concerned about that as well and can see it would happen if not properly rinsed afterwards... I didn't find any issues with all of the rifles I have used this process on as of yet.

[@JustinJustin2929]

Ive checked out alot of different methods, but think im going with mineral spirits, as opposed to degreasers,car washes, ovens,etc I like your pvc method too, im headed to Home Depot now...... Thanks

[@intoweapons]

about four hours. thanks for watching!

[@janegeary6013]

That's "cold" cosmoline removal, which you need to use harsh chemicals for. If you use the hot method, simple water with a few drops of degreaser is good enough. I know that industrially cosmoline is supposed to be removed with a very hot steam gun. Melting point of cosmoline is 52C/125F, and it turns runny enough to escape all of the crags in a rifle at 115C/239F. Just don't go over 300F or it burns.

[@intoweapons]

Good question, I used a hair dryer at full speed to blow dry it thoroughly. I then used a good amount of oil in the rear sights. Not the best way of doing it, but it works if that is all you have :)

[@ezrabrooks12]

I know this a old video, but will comment anyway. I use mineral spirits, kerosene, or automotive parts washer. I find they all work well. The simple green and other water based products just dont clean up as fast.

[@scottholmes6045]

I got lucky. The M44 that I recently just bought wasn't caked too bad in the cosmo. Nothing on the stock, Just the metal parts. I found that remoil worked pretty well for me. I still have to give the barrel a good cleaning but I need to get a brush and a patch hook that will fit

[@crazeyspivey]

I have 5 greassey Mosin's to degrease too. The one thing that I would do different is to not rinse these parts in water after their good soak in mineral spirits. I would just wipe them down with rags and then just use gun oil on them. If you do use water, maybe use it as the first step...to use warm water to rinse off most of the grease, then the mineral spirits dip, then the gun oil and reassemble and sling some lead down range.

[@intoweapons]

Glad the video helped!

[@Medmann48]

If you go to Home Depot you can get one of these long skinny totes for a grad total of $8.98. It is called a Pennington Window Box liner fits 36" window box (SKU 2318300010) & you will find this in the garden department outside is where I found it. This is intended as a plastic box liner for window boxes that outside you living room window. However it's quite thick so I think it will work fine for mineral spirits. because it is 36" long it will fit my M44, now 91/30 maybe. this beats PVC pipe.

[@intoweapons]

That's a great idea, thanks for sharing!

[@tm1180]

I know you mentioned this was your little "contribution video" but it's short, to the point and more information than this, is really not needed, if this isn't enough info for you, then you shouldn't be doing this type of work, beats watching 45 minutes of wasted talk and SHOOTING, ENOUGH WITH THE WATCHING PEOPLE SHOOT their guns for 17 minutes BEFORE THE FIRST WORD! you did a great job

[@gjohson1987]

Thanks for the quick response! I have seen and heard some people say mineral spirits can damage the blueing on the rifle or at the least make it come out with spots. I'm guessing you didn't run into this issue?

[@jesusdrummer21]

Hey it took 6 hours but the Mosin i did came out great!!! I soaked in the Mineral 3 hours, then hot water on parts, barrel I didnt do water just 105 patches, Yeah I counted) and hoppes 9, Wood I used alot of Dawn and warm water, and Zep Heavy duty Degreaser, didnt hurt finish at all, thanx for all the great tips!!!!!!!!!!!!!!!!!!!!!!! Saturday Nov 30th 2013

[@joshgrami]

Hi there, this video was actually very helpful. I have my M44 in the garage soaking in mineral spirits right now. You said it should be properly rinsed. What should I rinse it with afterwards?

[@intoweapons]

I personally wouldn't, just because the solvents get very dirty from the cosmoline... I imagine it wouldn't be too much fun cleaning the tub afterwards.

[@apex831]

Go to lss.com, that's LSS.com, lower case, it's a lab safety supply warehouse or graingers they both sell a poly tub that will work just as good as the fibre glass tub, about 23 bucks. The mineral spirits work well too. Thanks bro for the video

[@intoweapons]

Good to know, thanks for sharing.

[@dustins4921]

Were all the accessories coated in Cosmoline too? Did you go over them with a specific type of oil after you removed the cosmoline?

[@Medmann48]

Is it better to soak in mineral spirits or in boiling water? I have the PVC pipe like shown in this video but debating pouring boiling water in the pipe or mineral spirits to soak the barrel.

[@HowTo702]

Will start my cleaning on my 2 new 91/30's in a couple weeks. Do you think it's too hot in Las Vegas summer 115 degree summer heat to leave the wood outside? Good video, thanks. subscribed also

[@JustinJustin2929]

Just got one tonite..... Was all that crap(cosmoline) really necessary?? I think mine has more of that stuff on it than any of the rifles ive seen in the videos... Im gonna be busy tomorrow it seems...lol

[@MrMattyord]

Cheers dude mine just showed up in the mail caked in the stuff

[@gjohson1987]

how long did you let it sit in the mineral spirits?

[@JohnShaw26.2]

I live in St. George, about an hour and a half from Vegas! You should be fine in our desert temps. Ive heard of people putting stocks in the oven at 200 without problems. Where were you able to find your Mosin?

[@jstrunck]

Thanks for posting this vid!

[@Jagarff]

Can someone tell me if the mineral spirits will remove and bluing

[@intoweapons]

I think the brake cleaner would be considered a degreeser, but otherwise I just used Mineral Spirits/Paint Thinner.

[@HowTo702]

I found them at J&G and they were $119.. They have them again last time I looked for $150

[@bullseye887]

yes the cosmoline was completely necessary its was apparently the only efficient preservative they had in bulk for guns i dont think they would have used cosmoline if they had a cleaner/easier stuff to use in bulk -_- it isent that hard to remove anyways the only hard part that i see would be the stock

[@KC-bg1th]

The stock is the absolute easiest since you just let it bake in the sun. lol

[@paininthe10]

So as I can tell , mineral spirits is a paint thinner. No damage whatsoever to any parts?

[@intoweapons]

Nope, no damage from this process.

[@intoweapons]

It's neccessary to lubricate your bolt if you want to prevent corrosion. Operation of the rifle has nothing to do with my above comment.

[@marsjupiter8404]

Thanks good video helpful!

[@intoweapons]

Have fun! Certainly not one of my favorite jobs :)

[@cabrera757]

Should I submerge the stock in mineral spirit and let it be for X time?

[@intoweapons]

Antonified Fo dat I have never submerged wood in mineral spirits, not sure if that would be such a good idea.

[@cabrera757]

***** How do you recommend I proceed using mineral spirits?

[@intoweapons]

Antonified Fo dat I just moistened a clean rag well with mineral spirits and wiped the wood parts down. Maybe this vid will help too: kzbin.info/www/bejne/mmjYnHx9aahmgq8

[@jesusdrummer21]

That tub is hard to find, Maybe a garden store sells something that long? Lowes, Home Depot Ace, McLendens, nothing even close to that long, good score

[@intoweapons]

I believe this particular bin came from Brownell's.

[@CoastalBackWoods]

cheap plastic window boxes at Lowes are 2 feet long... work well.

[@chrismc410]

A deep and wide enough tote works too

[@MyVetteHeadLife]

Si how did you dry the barrel, being so long?

[@intoweapons]

I used a hairdryer and then ran some patches through it with the cleaning rod.

[@w1cny]

What did you use to remove cosmoline from the stock ?

[@intoweapons]

putting the wood in the over at 175 degrees for 30 minutes, and then wiping with mineral spirits worked very well. Otherwise, sitting in the hot sun and wiping away as it bleeds out works ok too (just a bit slower).

[@landronics]

IntoWeapons Do you think a heat gun/hair dryer would work?

[@M1GARANDxx]

Good video :D

[@JAlternative106]

your video helped me [:

[@xE4syComp4nyx]

russians built them to run dry. Its not necessary to lubricate your bolt. If you makes you feel better, go ahead

[@Road2Richies]

Mossin is another I've heard lol

[@jesusdrummer21]

ok did the baking in oven do anything to metal parts, what parts did you not put in oven? maybe a hair dryer? My wife will freak if i cook gun parts,

[@intoweapons]

no damage to the metal parts. I pretty much put everything in there except what was wood or plastic - essentially everything I soaked in mineral spirits was ok to put in. I have used a hair dryer before as well... I works ok, but doesn't dry it completely in unseen spots.

[@jesusdrummer21]

Well i didnt bake the parts but came out pretty good with Mineral Spirits, now i cant seem to get trigger in right, next 5 minutes ill have it, thanx for all your videos and help

[@dicktracy2049]

My wife would put my nuts in a vice and make me cry uncle until I put $200 in her purse and kissed her butt for a week. ;-)

[@jesusdrummer21]

So I did your cleaning on mosin and followed IraqiVet and another guy about the interruppter and polishing the bolt area and the mosin is like butter!!!!!!!!!!!!

[@intoweapons]

about 45 mins at 250 degrees, but it isn't an exact science :)

[@HabeasJ]

Lol, try finding a mosin in cosmoline today

[@barndweller4573]

I just purchased one and need to clean it so this video was helpful for me. Its almost December here in Michigan so the stock in the sun trick is not going to work for me.

[@CurlytopGaming]

My local gun store just got 2 crates of mosins in with 1920s and 1930s production dates and they're caked in cosmoline

[@alexdemers6365]

Mine had cosmoline . . . ALOT of cosmoline.

[@mixinthebisquic1238]

bruh all this shit for cosmo? just use some hot water and soap and some tinfoil jeeeeeez
