Just got this in an email from a friend and thought it was kind of interesting... not sure of the truthfulness but I'm always looking for the next best thing!
Rusty Bolts & Lubricant Fun Facts
Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts.
Significant results! They are below, as forwarded by an ex-student and professional machinist, Bud Baker.
*Don't forget the April 2007 "Machinist's Workshop" magazine comparison test.*
**
*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. *
