    I was traveling on business and got a late call from my wife. She was frantic that our daughter had gum or some other sticky stuff stuck in her hair. I directed her to the bottle of Kroil in the garage and the problem was solved :)

    Half and half automatic transmission fluid and acetone works just about as good as Kroil, at one heck of a lot lower price per ounce.

    And those two components are easy to find at retail.

    (Cribbed from the web bit follows)

    “The April/May 2007 edition of Machinist’s Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!

    Penetrating oil . Average load .. Price per fluid ounce
    None …………….. 516 pounds .
    WD-40 ………….. 238 pounds .. $0.25
    PB Blaster ……… 214 pounds .. $0.35
    Liquid Wrench … 127 pounds .. $0.21
    Kano Kroil …….. 106 pounds .. $0.75
    ATF-Acetone mix.. 53 pounds .. $0.10

    The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio).”

    Kano’s “Floway” is the bomb for real. Good stuff. WD40? No match. They make good products.
    (I don’t work for them!)

    I personally swear by a 50/50 mix of ATF and acetone. I normally use plain Dextron/Mercon, but anything from Type F to Pentosin works.

    Kicks Kroils butt at the cost of being hard to keep around. Crap plastic container? The acetone eats it away. Seal the container badly? All the acetone evaporates.

    Penetrating lubricant.

      Thanks so much. I was already thinking I’m the only one in whose mind this sentence kept echoing.
      However – it can never hurt to have plenty of good penetrating lubricant, so thanks for this post. But is it really dermatologically tested?

    Does the name Kroil have anything to do with Kroon Oil?

    Kroil? You’re soaking in it!

    I have never understood those who try to use WD-40 as lubricant. Do they not realize that the WD stands for Water Displacement?

    • bardfinn says:

      WD-40 isn’t formulated as a lubricant, but will act as one. So long as there is no appreciable load. Or speed. Or any particulate. In short, if your application is on a home sewing machine’s thread spool axle, it’s fine. It’s not fine for the sewing machine’s internal components (as a lubricant for operating the machine. For cleanup, it’s ok).

    • General Specific says:

      Just a guess, but it’s probably because it can be used as a lubricant. Says so, right on the can.

    seafoam makes a product called “Deep Creep” that works very well also!

    I’d almost forgotten about good old Kroil. I had a can of that stuff a few years ago, when I was working on my old ’68 Ford Custom. Kroil is good stuff, but I think it’s worth mentioning that most people won’t need it unless you do a lot of metal fab or restoration work (which is what the review is suggesting, anyway). If you’ve got an old car to pull apart, Kroil can be helpful.

    Nowadays, the most I need oil for is on the drill press and a few small parts. For that, 3-in-One, WD-40 or Liquid Wrench is fine.

    I have used aero-kroil and I bought a gallon just because I did not want to run out.
    I use is when I need it when nothing else works.
    I got some old 8 ton screw jacks(rail road supply) that were frozen and had been that way for a long time I soaked them for over a month and they have been restored to working condition.
    It is not for everything but when you need it it delivers wait a while and low and behold it is loose.

    Marvel Mystery Oil – my grandfather used that for about everything. You can still get it at auto parts store as a fuel additive. Light oil, ruby in color, smells nice. Use it on oilstones, as cutting oil etc etc.

  15. chgoliz says:

    I appreciate learning about the ATF-Acetone mix. For someone who has a large work area with many components, it’s probably the right choice.

    But for me, I’d rather have something small and easy that costs a bit more per ounce than something that requires multiple caustic ingredients and special storing. Price is not my deal-breaker in a situation like this.

    I use Krull for all my disassembling needs. I just play the DVD and everything falls apart.

    Ok, I am sold. I have a classic Jag that has plenty of rusted bolts and parts, and this looks like it could do the job. Also, in regards to WD40… You guys are right. It doesn’t do the job very well for very long. Growing up we had the “oiling can,” and it was much more effective and long-lasting then the WD.

    In regards to the ATF (or automatic steering fluid as stated – BTW, which one?)… I could be very wrong, but I am not sure if that would be very good once in contact with skin. Dangerous.

  22. Quibbler says:

    I normally used 2 stroke oil it works and is cheap. The advantage of wd-40 is the aerosol can which makes it easier to get at difficult to reach nuts.

  23. Anonymous says:

    doesn’t steering fluid eat through a lot, i mean if you had any non metal, nylon washers etc, or painted parts it could be bad

    kano kroil is also often used for a lubricant for target shooting. This might be where you can find it as its used to clean rifle bores and lubricate…

  25. mg@ak says:

    As a marine engineer I work with the MOST rusted fasteners. My preferred method is to heat with an Oxy-acet. torch and the apply aero-kroil. It is twice the price of regular kroil but it kicks major butt.

    is it me or does anyone else feel like they are reading a j. peterman catalog for cool tools

  27. LightningRose says:

    Diesel fuel is also a fairly effective penetrating oil, and it’s cheap enough to use for soaking large parts.
