Unseizing the Seized

For a moment let's forget the usual tips .....
Apply heat
Submerge in Diesel
Turn the wrong way first
Tap smartly with a thump'ometer
I found this recently: -
"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
So clearly "ATF/Acetone mix" is preferable, but what is it?
Well ATF is Automatic Transmission Fluid and Acetone is what women pour on their claws to clean off the paint they use on them.
So buy a bottle of ATF from Halfords (if you want to pay top whack).
A bottle of Nail Cleaner from Superdrug etc.
Then mix them 50/50.
