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.
