baking cosmo out


October 4, 2006, 09:53 AM
Hey guys those of you that have put your rifle in the oven to bake out the cosmolite what temperature and how long did you do it for, and did you use something like polyurothane to cover up the rifle after the baking?

The only "baking" I have done is to wrap the stock in a few black garbage bags and set in on the dashboard of my truck on a hot day. A few hours later, remove the stock, wipe down and repeat. Not perfect, but I wasn't going to fit a rifle stock in my oven.

You don't have to fit the whole thing in at one sitting. Bake at a low temp until it stops sweating cosmo. Remember to cool before serving, and enjoy:neener:

One of the best ways i have found to remove cosmo is to spray it with overn cleaner, let sit, rinse, repeat a time er two and its really cleans up nicely. I dont think i would any of the metal in the oven for fear of it changing the metalurgy properties.

Well i have it in the oven right now with the door open at aroun 180* i live in fl, and in the summer i have had the riffle in the car and it easily gets to around 150*, so i am not to worried about the mettal plus when i shoot it the barrel and metals around the barrel heat up more than that. O by the way the stock is the only thing in the oven i took the metal peices off.

What, pray tell, are you baking?

I dont bake cosmo off in the oven only becuse I know how good my wife can shoot :what:

I use WD40, q-tips and pipe cleaners. remove the cosmo, dip it part in boiling water for 5 minutes, spray with gun scrubber, then an over-night bath in break free. Works like a charm and I don't fear the boss.

I like baking the stock because you're not stressing the wood with powerful chemicals. Put it in your oven at it's lowest temp (usually 150-180F) and take it out every 15 minutes to wipe it down (just like .45 guy said). After about 45-60 minutes it will stop oozing out. I've done this to 3 stocks and it works perfectly...the wood finish is unchanged.

Pro-tip: make a small pan out of aluminum foil and place it under the end of the stock to collect any drippings while it's in the oven.

thanks for the help guys.

I always use Easy-Off oven cleaner on stocks. Just spray on, leave sit for 15 min, then spray off with hose. Do this a couple times, and wood is clean and like new(of course you have to refinish it). Don't worry about harming the wood with oven cleaner. I have done it to 6 or 7 stocks now, and none have been harmed in any way.

"Ummm, hi honey, didnt know you'd be back from shopping this early. I promise I'll clean the oven, please dont make me sleep on the couch." :neener:

How bad does baking it stink up the oven and kitchen? (And house...)

Does it smoke a lot? It looks like it would make the house smell for a while.

I only bake milsurps when the wife is out of town. Unless you have an enclosed kitchen, the smell tends to go around the house. We have a kick-ass kitchen exhaust fan that ventilates to the outside, but that only helps keep the smell and smoke down to some extent.

Oh, about the smoke, I triggered the fire alarm once or twice. It helped that, like I said, the wife was out of town. ;)

I'd think kitchen oven is quite safe on metal unless you got something at goes to several thousand degrees F.

It does leave a certain aroma, but I just consider it a cheap alternative to Glade scented oil;)

I tried the oven method once, years ago. It was with a Yugo M-48 stock, and it caught on fire!

October 4, 2006, 01:21 PM
That would make for an interesting insurance claim.... My home burnt to the ground from a grease fire caused by baking a rifle stock:D

Try coating the stock with painters whiting (get it at a paint store), put the stock in a heavy garbage bag and leave it in hot sun or inside a closed up vehicle in the sun. This stuff draws oil and cosmoline residue out from the stock pretty well.

If you do more than one or two rifle a year, I saw a post somewhere once that used two 33 gal garbage cans, a plywood washer, and about half a dozen 100 watt lightbulbs. That way you can do your 'baking' outside and not have to worry about checking to see if you have over cooked your rifle so often. Will see if I can track down the link.

The only two links I could find, but you can get the idea. The one I saw used two cans, one inverted over the other with a plywood washer(circle with a hole cut in it for the rifle stock) between the two, and lights in both cans, just hang the stock or entire rifle from the inside of the top can, plug in and let 'cook'.

Not too sure I would reccomend the second one....

I just refinished a Colt M16A1 upper from CDNN in Brownells baking laquer. I managed to thoroughly clean the upper reciever, painted and baked the 2 halves at the same time. On the barrel, however, I only painted the front sight base. Cooking at 300 for 1 hour, the base around the barrel oozed out cosmoline for a good 20 minutes. Scented the house up better than the baking laquer! Note, wife was at work, kids were at my parents. I was awoken around 0200 when my wife got home.


Slept from 0215 to 0630 on the couch.

For a really soaked stock, heat and time are the only things I know of that will get it all out. If in a place where it gets hot during the day, you can deep-clean by wrapping it with paper towels- including stuffing the receiver recess and barrel channel- then putting it in a plastic bag and putting it in the sun. Or in the car or trunk, wherever it will get hot. Heat causes the grease to bleed to the surface and the towels soak it up. Do that several times, and then wash it with mineral spirits to get the surface clean.

Used heat gun on my 1903A3, just can't get to carried away. Runs off like melted wax.

Kharn - how did you get away with it? I see you still have hair on your head too.

BTW, consider a steam cleaner for the metal. Be sure to hose it down with a spray on oil like Break-Free afterwards.

I've used the bake-in-the-oven method on all my milsurp stocks.

Personally...I love the smell of warm cosmo...:neener:

Mineral spirits, just dissasemble the rifle and dunk the parts in it, works great.

October 6, 2006, 01:42 PM
Mineral spirits work, I've used the oven too. Seems like I set it around 150-200. Covered a cookie sheet with aluminum foil and set the stock on that to catch stuff that ran out. Also baby-sat it, wiping occasionally to keep too much from puddling up.

A few actual quotes from DSW:
"Why is there a gun in my bathtub?"
"What are you doing with the oven?"
"Where is my iron?"

She's a good sport about it all. I think I'll buy her an SKS to show her how much I love her. :)

Thats not me in the picture, .45 Guy posted it and I included the color commentary. I use a heat gun on my C&Rs, cleaning my gas oven is too much of a pain in the butt to try to use it for getting cosmo out.


October 6, 2006, 04:19 PM
i actually used a rotisserie on my mauser stock over our grill, without the plates in place... change coals, wipe under tray, done

October 6, 2006, 11:37 PM
I tried using the wife's oven to bake on the finish on a pistol once-just once.
I will never again attempt doing anything more with gun parts in the oven.

The smell was overwhelming and further more, the grief from my wife is just
way too much brain damage. Moreover, I think if I tried to bake on a finish
or cook out cosmo in the house again my wife would take up shooting----at me.:)

I would like to consider getting a new oven for the house and installing the old one in the garage if I had more room. An oven would be very handy to have for some gun projects.

Thats not me in the picture, .45 Guy posted it Yep, and the worst part is it isn't me, or my rifle stinking up my kitchen. One of my buddies from the old MWSS-27Screw came up from Illinois and picked up a 24/47.
