    I picked up a re-arsenaled Mosin 91-30 yesterday, thankfully, the LGS took the time to remove 99.99% of the Cosmoline preservative from the gun, the bayonet, however, was still gooped with the stuff, especially on the barrel mounting pivot

    for some strange reason, the brownish goop looked familiar, then it hit me....

    it looked remarkably similar to the little tub of Birchwood Casey RIG Universal Grease I use to keep my guns rust-free (we have a salt marsh on our property, and caring for blued guns takes a few extra steps beyond the typical wipe down)

    So, I googled Cosmoline, and read the Wiki entry on it, one thing caught my attention, that Cosmo has a "slight flourescence" when exposed to UV light....

    So, I grabbed my TerraLux UV LED equipped Minimag flashlight, and shined it at the bayonet, sure enough, the cosmo glowed an eerie blue....

    Cool, an easy way to check the rest of the rifle for Cosmoline....

    I then opened the tub of RIG, shined the UV light on it, it had a greenish-grayish-bluish color, close, but not a perfect match.....

    then again, the RIG was fresh, and the Cosmo was more than likely badly oxidized, that may explain the color difference (or perhaps Cosmo and RIG are not exactly the same thing)

    it's not a definite answer either way, but I think it's safe to say that RIG is at least rather *similar* to Cosmoline....

    Just a fun bit of trivia....

    RIG has been used in my house since my dad was in college a good 25 years ago. The feel is different than cosmoline and so is the smell. I'll keep using RIG until I run out then get some more. It not only keeps rust off, but it makes the metal look much better once properly wiped down.

    RIG grease has proven itself with my weapons for well over 45 years. I do believe that it is the one thing that is never missing from my gun cleaning box. Great lube for moving parts. Fantastic in keeping the rust away. As I said, I'm never without it. Works great as the lube for my C&B revolvers base pins. It will not gum up and it will let the cylinder move in spite of some heave fouling that sometimes forms. Not an easy task for other lubes.

    RIG is really good stuff, for long term storage of firearms. Yes, RIG and/or
    Cosmoline can be "tactfully messy" at times; but it preserves firearms really
    well. I've used it for a very long time, over the course of many year's~! :cool:

    I will use NOTHING else to wipe a gun down but RIG.
    10 inch square piece of Sheepskin with a liberal dollop of RIG rubbed in ??

    What is the best way to clean off cosmoline? I've got a bunch of old mags that are covered with it.

    Best way to clean cosmoline is hot soapy water and lots of scrubbing. That is the way the Navy trained me to remove cosmoline. Then quickly dry and oil.
