I haven't tried it.
"Machinist's Workshop" recently published information on various
penetrating oils . The magazine reports they tested these products for
"break out "torque" on rusted nuts and bolts. A subjective test was made of
popular penetrating oils, with the unit of measuremerit being the
torque required to remove the nut from a "scientifically rusted" bolt.
Average torque load to loosen nut:
No Oil used ........................516 foot pounds
WD-40 ..................... ........238 foot pounds
PB Blaster .........................214 foot pounds
Liquid Wrench ....................127 foot pounds
Kano Kroil .........................106 foot pounds
ATF/Acetone mix..................53 foot 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 = Any type of Automatic Transmission Fluid
This version of the story was in one of the Military Vehicle Club newsletters.
