CLR or any one of a slew of chemicals.

Ajax or comet cleanser. It comes in a round can shaker and you put on a prewetted sink and sand off the stain...with a super fine abrasive.

Comet cleanser should work. Get the bottom of the sink wet. Liberally sprinkle Comet cleanser over the bottom of the sink, covering the stains. Keep the powder moist and let it sit for about 1/2 an hour. Cover it with damp paper towels if you have to. After it has soaked a while, start scrubbing the sink with the damp powdered cleanser using a nylon scrubbie or similar non-scratching tough scrubbing sponge. A lot of elbow grease and Comet should get rid of the stains. Repeat as necessary.
