CLR usually does the trick
Calcium Lime Rust remover. Just be sure to clean thoroughly afterward.

Those little plastic squeezy lemons at the grocery store will do it as well as straight vinegar if you don't wanna use CLR. They use CLR to clean the coffee pots at work... I don't drink coffee at work! LOL

I found the best solution was a a window scrapper (razor blade with a handle), vinager and elbow grease. CLR or other not-good-for-you chemicals didn't work for me.
