Penetrating Oils
Machinist's Workshop recently published some information on various penetrating oils. The magazine reports they tested penetrates for break out torque on rusted nuts.
Below listed, a subjective test was made of all the popular penetrates, with the control being the torque required to remove the nut from a "scientifically rusted" environment.
Average torque load to loosen
No Oil used ................... 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 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 20% of the price.
ATF-Acetone mix is best, but you can also use ATF and lacquer thinner in a 50-50 mix. (ATF=Automatic Transmission Fluid)
