Ceramic Hooks I Have A Marble Sink For The Bathroom. It Has Cigarette Stains. How Can I Remove It Off ?

I have a marble sink for the bathroom. It has cigarette stains. How can I remove it off ? - ceramic hooks

I'm trying to sell new, never connected. However, someone put a cigarette in her, and tried to chlorine bleach and Comet Bryte CERMA for stoves, but the stain is still there. Ideas to remove it?
