I seem to recall alum is/was used in some pickling recipes, (as in
cucumbers) ; you might check in the spice section at the grocery
store.

Alum, or Aluminum Potassium Sulphate, when added to water is Sulfuric
Acid.
Available in flooded cell auto batteries, and in the drain cleaner
section of some hardware stores.

Nasty stuff on skin or eyes.
I have no idea if it reacts with Bronze, but it does dissolve steel,
heat speeds up the reaction.
