Friend of mine sent this to me knowing I love all things that make life easier so I thought I'd share. Don't shoot the messenger. I'm just passing it on and found it interesting. Have not tried it but I will.:beer:
Subject: Penetrating Oils
"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 merit 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
