Personally I've never had a single success with so-called penetrating
oils, not one time in 40+ years, not ever. The only thing I've found
that's guaranteed to work is heat; not just butane or propane heat, but
oxy-acetylene heat. Heat the ****er up till it glows bright orange and
away you go. Never known it fail.




I have seen that done on a nut that was basically a ball of rust on the
end of a Landrover wing mirror arm. Most impressive.

Low oxygen produces a reducing flame and turns the rust back to iron
(powder?) again
