Well this was interesting I thought! Gonna have to start mixing my own shit!
Otherwise I'll also be ditching the PB Blaster for the Liquid Wrench.

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.
Our local machinist group mixed up a batch and we 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.
