I was burning a cone incense and left it on the sink, and this stain won't come off. I tried baking soda, water, vinegar, hydrogen peroxide. I tried letting them sit for multiple interations, and it made no difference.

I'd be tempted to try sandpaper, and find some matching acrylic paint to reseal it.

I would likely try the methods of car headlight repair:

fine sandpaper (e.g. 600)
followed by ultra fine sandpaper (e.g. 1000)
followed by polishing sandpaper (e.g. 2000 or even more)
followed by polishing paste (e.g. cerium oxide) on a felt pad

However, since I see that the sink has a glossy surface... I would be deterred by that. The method I mention may reach a layer which isn't burnt, but will wear off glossy finish and there's no certainty of it returning in the same tone after polishing is done.

What paint to use - sorry, no idea.
