Vikki,
I've heard that alum (food type stuff, concentrated and hot) will work
for steel taps in aluminium... no personal experience. On the rare occasion
that I bust a tap ;-) I use jewellery sparex pickle, also sold much cheaper
as Ph down for swimming pools and hot tubs by most hardware stores. Use
warm for a few hours just like the alum. Not too nasty other than the fact
that a drop on your clothes will result in a hole after a few trips through
the washing machine. And don't drink it, tastes awful and will rot your
teeth ;-).

Next time you might try 10 to 15% nitric, assuming it was stuck in
Aluminum. The aluminum will be passivated with a very thin layer of
oxide and the nitric will not penetrate it any further. The steel
will be eaten away post haste.
Thanks Arnie,
I'll keep that in mind for when I have someplace other than an apartment
as a shop. A bit leery about serious chemicals in this environment.
This whole experience sure will keep me a LOT more careful about tapping
it the future though.
Thanks & take care, Vikki.
