That's how I restore rusty black pots. It may take a few treatments, but it usually works wonders. Same with calcium deposits on plumbing fixtures. I don't see why this would be any different. It's always a good practice to start with the least harsh method first. At least that's the rule I always use.

I would definitely stay away from the muriatic acid though. I've used it to clean water stains off of my fiberglass boat and I distinctly remember the instructions warning not to use on aluminum. The runoff had a pretty harsh reaction on the galvanized trailer as well.

Vinegar will eat about anything you can imagine if its left there long enough. Seen it strip galvanizing off in about an hour.
