How do I get stains off my porcelain sink?

I have a Kohler double porcelain sink (its Bisque color and about 10 years old). I love my sink, but there are some light brown stains I'm unable to remove. I've tried Bartender's Friend, and it helps somewhat, but doesn't remove the stains around the drain (which are darker). Do you have any suggestions on what I could try that would remove the stains.
