Quoted: Not sure what it is. Ordered some GI M1 Carbine mags and they came in literally coated with some sort of black/dark grease. Is it cosmoline? Any tips on how to remove this? I was wondering if boiling water and dish soap would be sufficient. |

Heat melts away the cosmo.. An oven, coat hangers, drip catcher. Low heat, patience, vois la. |

Some things I have used. A bunch of rags/paper towels to wipe off as much as possible. Foaming brake cleaner. Laying the items out in the hot sun and wiping away whatever softened up.
Generally my most effective method is to get an old metal dog bowl, or a good size pot from a second hand store. Boil some water and dump the parts in. Drain and scrub the parts frequently with a GI toothbrush. This may take a few cycles. I also find adding some Dawn dish soap to the boiling water helps. Beware of rust forming quickly. Wipe off all water. Sometimes I blow the parts out with a compressor. If you are in a hurry, line a cookie sheet with aluminum foil and bake the parts in your oven to dry. Some final thoughts, I have a dedicated set of used cookware just for these kinds of things, never use them for food again. Bonus points can be had if you do it when you boss lady is out for the day, don't invite and angry wife into your life. Hope some find this helpful. |

The stupid easy way is to put them in a disposable tin pan lined with newspaper and stick them in your oven at 200 or less degrees. Most ovens have a 175 or 180is barely on setting

I use my brothers' automotive parts de-greaser, has a solvent in it that just melts and washes the stuff away.

Bath in low odor mineral spirits. I usually fill a paint roller tin and let then the parts sit overnight, the cosmo will literally melt away. After drying wipe down with WD-40.
This process has worked every time on even the thickest cosmo. |

Disassemble them and Put them in an aluminum plan and cover them with water. Heat the pan to almost a boil and watch the grease float to the top of the water. Take the parts out of the water, try not to burn yourself, and then wipe down the parts with your preferred lube and reassemble. Throw away the pan and water.

Yep, i cured some cerakote'd parts while the wife was away, but she clearly smelled the residuals afterward. Had to buy a new oven for her the next day. At least i now have a dedicated oven for projects in my shop now. |

I use mineral spirits.
I have them soak completely submerged for an hour or so. I then pull them out and bathe them in boiling hot water. dry things up and give it a good coat of oil afterwards. |

I've put small parts in a pot of boiling water before, it worked really well. You might still need to use a chip brush or something to loosen some of it. When you pull the parts out, the water will flash of quickly so they won't rust. They will be bone dry, however, so oil them as soon as you're all done.

My father was issued weapons new in cosmoline, The went to the mess hall with bales of rags where the cooks had gallons of boiling water ready.
Remember dish soap contains salt so you might want to avoid that. |

I am not sure if there are various substances being used as cosmoene or if it just differs due to age or method of aplication . Likely both .
At any rate results will vary a great deal . I did a non issued yugo SKS that worked fine with some paper towels , Q tips and a can of WD-40 . I had a old enfield that looked just a bit dirty on the outside but everything inside and under the wood/in the wood had some kind of nasty crud that was a bitch and a half to soften/wipe off. I am a fan of the wrapping it in paper towels/newspapers /black plastic and letting it sit in the sun or a closed up car in the sun . This method is not foolproof and not fat or complete but it is very easy and doesn't take much time . The harder the stuff is the more heat is your friend . If a wood stock is involved solvents are not a great idea , mild heat (150-180F) is the way to go |

I use a two gallon clear pretzel can with gasoline for parts with cosmo. Drop in the mags, cover with just enough gas and let sit overnight. Slosh around in the morning and you're done.

Sometimes more than a couple times. I also built a solar oven and that was awesome for getting the grease and oil out. Got to be careful though it can get way too hot. For metal parts wipe off the excess grease then use Wipe Out foaming bore cleaner. Put the parts in a tub, cover with foam, let it sit, scrub off with toothbrush, then oil parts. |
