Stuart,

It was on this list in 2010, that tests of penetrating fluids were  
reported.  The best was home made from a 50-50 ATF-Acetone mix.  Here  
is the post:

    Friend of mine sent this interesting test result.  Gonna have to  
try it.
Could have used it this morning.

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.

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.
