Penetrating Oils Compared

Machinist's Workshop magazine actually tested penetrates for break out
torque on rusted nuts. Significant results! 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 ..... 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.
