About 4 years ago I was brazing up a prototype bike frame from EMT and
I used 'some kind' of household product to remove the galvanizing, in
the area of the joints.

Now I can't remember what it was that I used.

I do remember that it was a liquid, that I put some in a glass jar and
stood the end of the tube in it and also that it fizzed and bubbled
somewhat.

If you would jog my memory here, I'd appreciate it.

"spirits of salts" is its traditional name - used by roof plumbers for
removing galvanizing on guttering prior to soldering. Comes in small
glass jars. Applied with home made brush - piece of copper pipe belted
flat on a bunch of horsehair. Probably NLA now, but worth a try at
your local plumbing supplies store.
