Yes, it does indeed. I unscrewed an elbow for an Onan exhaust
manifold, that was impossible to remove without penetrating oil (PB
Blaster). It was impossible to take off, but after liberal spraying
with PB Blaster and waiting, it came off relatively easily.

THAT's the nasty stuff I was referring to!

They came off nicely.

But, I still am not sure if I believe the oil did anything.

Is there any scientific research into this stuff.

My next experiment is going to be an old rusty exhaust manifold.
