Advice removing water stains on front curtains

For what it's worth, we had a similar issue. Wifey brought them to a dry cleaners, charged us more than I thought she should (forgot how much, wanna guess $75-$100) and they really didn't look that much better. They were cleaner, but the water stains were still pretty visible.

On my very long "to do" list, is to try the oxy-clean type products, so I'll be interested in how your success story turns out. :)
