Some info I found on interwebs about penetrating erls ... not sure if its true but interesting

Penetrating Oils Compared

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 Automatic Transmission fluid (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.

I did similar research when I was at the same place. Some other tests had Kroil and the homebrew similarly ranked. Kroil often has a special running on their website. I think I bought one can and got SiliKroil free with free shipping.

I had already tried the Liquid Wrench, PB Blaster and CLP without success and didn't want to fool with the mixing and storage or using it around heat.

The automatic transmission fluid doesn't affect the bluing?

This. ATF / Acetone will work 99% of the time on things like this. Liquid Wrench is my go to commercial if I don't have any of the home brew ready to go.
