Help Cleaning a White Kitchen Sink, that Is Stained ?

I have a white kitchen sink (Kohler) Porcelain, that I tried Ajax, Comet on and it just won’t come clean. Please any ideas. It hasn’t been cleaned in about 15 years. Maybe doing the comet/ajax 10 times, or letting it sit overnight? Using toilet bowl cleaner? Ideas … Please. Ty!
