Found this on another forum. I thought it would be interesting discussion here.


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 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've been using a 50/50 mix of ATF and acetone for some time now. I don't know how I got by without it before

Article is from 2007 so it might have been around the block already.

Note the correction from ATF to PSF.
