Oxalic acid. You can buy a pound or 2 at the local drug store and mix it with water.

Does it react with the galvinized metal?

Yes, and it turns aluminum black and pits stainless. Rinse with lots of water if you do get it on any metal.

Yes the stuff works great. IIRC the label states that it also contains hydrochloric <SP?> acid

If its got HCl in it, keep far from stainless, it will remove the natural passivation layer and attack the SHEET out of it.
