Penetrating Oils

 

Machinist's Workshop Mag recently published some information
on various penetrating oils that I found very interesting. Some of
you might appreciate this. The magazine reports they tested penetrates
for break out torque on rusted nuts.They are below, as forwarded by an
ex-student and professional machinist. They arranged a subjective test
of all the popular penetrates with the control being the torque required to
remove the nut from a "scientifically rusted" environment.

*Penetrating oils .......... Average torque load to loosen*No Oil used .................. 516 poundsWD-40 ..................... ... 238 pounds
PB Blaster .................... 214 pounds
Liquid Wrench ..............127 pounds
Kano Kroil .................... 106 pounds
ATF*-Acetone mix..........53 pounds     *ATF=Automatic Transmission Fluid

 


The ATF-Acetone mix is a "home brew" mix of 50 - 50 automatic transmission fluid
and acetone.
Note this "home brew" released bolts 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 almost as good as "Kroil"
for about 20% of the price.
