  • Thoughts on Penetrating Oils from "Machinist's Workshop" Magazine

    "Machinist's Workshop" recently published information on various penetrating oils. The magazine reports they tested these products for "break out "torque" on rusted nuts and bolts. A test was made of popular penetrating oils, with the unit of merit being the torque required to remove the nut from a "scientifically rusted" bolt.

    Average torque load to loosen nut:

    No Oil used ........................516 foot pounds

    WD-40 ..................... ........238 foot pounds

    PB Blaster .........................214 foot pounds

    Liquid Wrench ......................127 foot pounds

    Kano Kroil .........................106 foot pounds

    ATF/Acetone mix...................... 53 foot 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 20% of the price.

    ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a 50/50 mix. ATF = Any type of Automatic Transmission Fluid.
