We have a dripping bathtub faucet. This is a conventional two valve faucet
with stems sticking straight out of the wall, about 50 years old. It's
probably just a simple matter of replacing the washers but I have to get
the handles off to do that. They may not have been off in a half century
and naturally they don't want to budge. Any ideas? Bag them with a
solution of CLR?

I suppose if worse comes to worse I can cut them with Dremel cutting wheel
and replace them.
