Kroil, or more properly, Aero Kroil is widely regarded as being the
best. As far as I know it is sold only on the web but you might be
able to borrow a can from a professional mechanic.

PB Blaster is also pretty good and is widely available at auto parts
stores.

Apply, tap lightly with a hammer, reapply, and let it sit overnight
before using a bit more and tapping again with a hammer.


Just caught up with this thread...

I have to agree with Wayne about Kroil. Having used it on various
applications including aircraft for years, I'd say it's one of the best
I've used.

That said, you may want to be careful what you get it on because it will
dissolve a lot of synthetics (rubber, plastic, etc.)

Another pretty good one is wintergreen oil. I have a can I got surplus
from the Airforce and it not only smells good, it works great.
