    Default Penetrating oil

    Machinist's Workshop magazine actually tested penetrates for break-out torque on rusted nuts. 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 Oil and Average Load*

    Nothing..................... 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 was a "home brew" mix of 50-50 automatic transmission fluid and acetone. Note the "home brew" was better than any commercial product in this one particular test. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price

    kerosene should be mentioned also, works very well as a cleaner. I always have some in a small spray bottle. One of the major heating sources in Japanese homes is kerosene (toyu 灯油) which is readily available at just about every gasoline stand. Usually we buy it in a standard red color 18 liter plastic tank for kerosene.
