    Kroil and my long lost micrometer

    My basement flooded for the first time ever about 15 years ago. Much of my reloading and casting equipment was down there stored in various containers. Some of the containers floated around or sunk and filled with water. Much was ruined. Fortunately all my loaded ammo was in military ammo cans with intact seals and survived.
    This particular story is about a micrometer that had gotten lost in a small soaked container and not found for several years. Nothing special about the micrometer. It was rusted sufficiently that the adjustment knob would not turn at all. I tossed it aside and thought I had thrown it away years ago.
    A couple of years ago I moved and apparently that micrometer moved with me. I found it last week while searching for some other things and laid it on my gun cleaning table. Just for grins I sprayed it heavily with Kroil just to see if there was any hope for it. This week I stumbled across it again while cleaning some pistols. When I picked it up, it still wasn't wanting to turn. I gave it a light tap on the table and it started turning.
    After a very short time it regained full movement and now opens and closes completely. UNBELIEVABLE.
    Kroil is really good stuff.

    I'm sorry to hear about loss & glad you got your micrometer freed up.

    Kroil is excellent, but expensive. (ATF)/Acetone mix (50/50) is actually better and cheaper

    Rust Remover/penetrating oil
    “Machinist Workshop Magazine” did a test on penetrating oils.
    The torque required to loosen them.
    PB Blaster: 214 lbs;
    Liquid Wrench: 127 lbs,
    Kano Kroil: 106 lbs
    (ATF)/Acetone mix (50/50): 50 lbs.

    Now that its turning remove the thimble sleeve and see if there is a collet thread nut on top of the thimble. If so a little flitz or other very fine abrasive and wok stop to stop for several minutes then clean and assemble with a very light oil. Adjust the collet down alittle at a time and they may become accurate again also.

    Repeated application of kroil got the buffington sight on my trapdoor moving freely again.

    Kroil stinks almost as bad as Ballistol. Just seems most people can take the Kroil smell.

    Thanks for that info. I wasn't aware it did that. I think I will use some of my gun oil on it.

    Surprisingly enough, I graduated high school back when it was necessary to know how to read, it is indeed Kano Kroil.

    Different stinks for different folks. Ballistol doesn't bother me at all, while Kroil smells awful.

    About 20 years ago I had occasion to take some stuff to our son and daughter-in-law in Nashville. After delivering, I went by the Kano plant and bought a gallon of Kroil. I think it cost about $35. I've used it ever since and gave small cans away and still have more than I'll ever use. Works great for cleaning barrels(lead not copper).

    I have read the American Machinist report several times and have no issue with it. My issue is with acetone. I don't like the stuff. I don't often run into world class frozen assemblies and therefore will stick with Kroil.

    The only problem I've had is remembering to set little squirt cans on aluminum foil on the shelf. The stuff will "creep" out and soak the wood(osb) shelf.

    I like Kroil. I like the smell, how it works and how little it takes to get things going again. Got my first can from the tool crib at the machine shop I worked at years ago. It lasted a long time. Got 3 more cans a few years back from Kano Labs. It was a buy 1 get 2 free deal I believe. I also have some milsurp solvent that I swear is Kano Kroil. Smells the same, works the same etc. I have a big can of it.

    For the record....I have never heard of Kano Kroil "gumming up". I have heard WD40 doing that. WD has no place around guns or precision equipment EVER!

    Also as a side note after I bought the Kroil direct from Nashville, They sent me their newsletter for about 2 years afterward. Really neat stuff.

    Yup, WD-40 will turn an orange color and get hard as a rock. I have a pint can of kroil a service man gave me when I was working at the sawmill. That was over ten years ago and I still have at least half of the can. When I first started using it I couldn't stand the smell, but now it doesn't affect me. The LGS had some Ballistisol wipes as a giveaway, I took three home and was really surprised. I ended up buying a can. It smells a bit strange, but works well. When I have the need to really clean my bores a Kroil soaked patch will go through first. It will loosen anything, at least in my firearms.

    I seem to remember someone posting that Kroil was good for loosening lead deposits in barrels. I have never tried it but it is a good thing to remember just in case.

    Kroil is great stuff. It will clean lead deposits as well. Just takes a little more time, and two or three soakings.

    I agree. When I used WD40 a lot was on fishing reels that were used and cleaned often. If a part, or tool is to be cleaned and put away for any period of time I use Kroil. I have used Kroil on barrels as I've read that it will creep under/between the leading and the barrel. Seems to do so 'cause it works...

    Nobody speaks to the major downside of this stuff. I had two smaller cans of Kroil in amongst all my reloading equipment and when I moved it remained with the equipment in sealed cardboard cartons in my garage for 14 months.

    You must understand I live in Las Vegas. These cans went trough two; I repeat two scorching Las Vegas summers. From June to late September the temps range from 70 to 120 degrees with at least 80 days higher than 100 degrees and 20 or so higher than 110 and handful higher than 115.

    Those two cans had fallen over and leaked everywhere in those cartons. Then to the cartons alongside and under until I had a stinking mess.

    Now I have to go out and buy some more because it is great stuff.
