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 start with cardboard, it’s can give you clue if using the lightest sandpaper would work. you could probably use a clear finger nail polish to top it
