Penetrating oil, vibration and time work well together. PBblaster is better than WD40, but it stinks. I definitely would NOT use it indoors. Although I was recently told that now, they make PBblaster that doesn't smell too bad. Mine is probably ten years old, so it is certainly the older version.
I'm not familiar with the parts you are trying to remove. Is there a keyway? Could it be that there is a tapered keyway that tightens more as the crank is pulled out?
No keyway. Cranks & bottom brackets might be left for 10+ years or more. They are in the bottom of the frame, so _any_ water that gets inside the frame ends up down there. Additionally, they are TIGHT and almost always take a special tool.
He posted he is using locking pliers... so that is a BIG limiting factor right there. Sometimes, you can put the took in a vise, and turn the entire bike frame to gain leverage.
