Scientifically rusted

This one's from Sastard Sr. via the old curmudgeons at CVMG.

Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts with 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 (obviously a BIG nut!).

Penetrating oil ...... Average torque

None ....................... 516 ft lbs

WD-40 ................... 238 ft lbs

PB Blaster .............. 214 ft lbs

Liquid Wrench ..... 127 ft lbs

Kano Kroil ............. 106 ft lbs

ATF-Acetone mix....53 ft lbs

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. Our local machinist group mixed up a batch and we all now use it with equally good results.
