    rust and penetrating oils

    just sharing, hopefully it is helpful.
    Subject: rust

    Machinist's Workshop magazine recently published some information on
    various penetrating oils that I found very interesting. Some of you
    might appreciate this. The magazine reports they tested penetrates for
    break out torque on rusted nuts. They are below, as forwarded by an
    ex-student and professional machinist. They arranged a subjective test
    of all the popular penetrates with the control being the torque required
    to remove the nut from a "scientifically rusted" environment.

    *Penetrating oils ........... Average torque load to loosen*
    No Oil used ................... 516 pounds
    WD-40 ..................... ... 238 pounds
    PB Blaster .................... 214 pounds
    Liquid Wrench ...............127 pounds
    Kano Kroil .................... 106 pounds
    ATF*-Acetone mix. ...........53 pounds

    The ATF-Acetone mix is a "home brew" mix of 50 - 50 automatic
    transmission fluid and acetone. Note this "home brew" released bolts
    better than any commercial product in this one particular test. Our
    local machinist group mixed up a batch and we all now use it with
    equally good results. Note also that "Liquid Wrench" is almost as good
    as "Kroil" for about 20% of the price. Steve from Godwin-Singer says
    that ATF-Acetone mix is best, but you can also use ATF and lacquer
    thinner in a 50-50 mix.

    *ATF=Automatic Transmission Fluid

    Will the Acetone or Lacquer do harm to paint? or any other finishes?

    Re: rust and penetrating oils

    my guess would be YES. guess i had not thought of finishes because they were not present where i have used it.
    if ya make up a batch be sure to put a warning label on it. if your memory is like mine.

    Has anyone here used Mouse Milk? I have had a couple of bottles for several years and it has always worked great. I wonder where it would fall in this chart?
