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 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 almost as good as “Kroil” for about 20% of the price.

Steve from Godwin-Singer says that ATF-Acetone mix is the best and you can also use ATF- lacquer thinner 50 - 50 mix.







*AFT=Automatic Transmission Fluid

TweetGood stuff.. I order Kroil by the case. Mixing my own just isn't practical for my job.
