Machinist’s Workshop Mag™ recently published some information on various 
penetrating oils that is very interesting. You might appreciate this. 
The magazine reports they tested penetrates for break out torque on 
rusted nuts. They are below, as forwarded by a professional machinist. 
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 .......... Break out torque*
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 and you can also use ATF- 
lacquer thinner 50 - 50 mix. Note also that “Liquid Wrench” is almost as 
good as “Kroil” for about 20% of the price.
