I once prevailed upon a museum friend to agree that his lab might *just
possibly* be willing to ultrasonically clean something for me.  Then I
learned that their sonicator was a water tank something like 3"x3"x10".

I haven't kept up so I dunno if bigger and more powerful units are now
commonplace or not.

I find that electrolysis in warm, dilute phosphoric acid goes faster
than bicarbonate, is less noxious than than HCl and leaves the iron
surface in a more stable -- more rust-resistant -- state.

FWIW,
