Machinist's Workshop magazine actually tested penetrants for break out
torque on rusted nuts. Significant results! They arranged a subjective test
of all the popular penetrants with the control being the torque required to
remove the nut from a "scientifically rusted" environment.



Type of penetrating oil ..... Average load



None ................................ 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. A local machinist group mixed up a batch and all now use it
with equally good results. Note also that "Liquid Wrench" is about as good
as "Kroil" for about 20% of the price.
