Yup! That's the same sodium bisulphate as the pH down product for
pools/spas. It's quicker than alum (any of the common variants) &
easy to get.

I'm not quite sure by your comments whether you have used Sodium
Bisulphate to extract broken taps. If you have then that
substantiates my assessment that it is the sulphate ions which do
the
work. Being a bisulphate the iron ions do not need to displace the
sodium ions to form sodium hydroxide (corrosive to aluminium),
they
just neutralise the solution forming iron sulphate and sodium
sulphate.

Found this at my local homebrew store:
productid=285&cat=0&page=1
Would that work?
Convenient place to get to (something special in Seattle) and I do
already go there from time to time.
Embarrassed to admit what chemistry I did take has long since been
forgotten <blush>.
Thanks & take care, Vikki.
