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.

When my can of Kroil runs out, I'm going to try the ATF-Acetone mix!
