Penetrating Oils Compared

Machinist's Workshop magazine is reported to have tested penetrants for break
out torque on rusted nuts. (I'm waiting for vevrification)

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.

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.
