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.
rubbing alcohol might help but your probably going to have to buff it out with a Dremel
Would using super fine sandpaper be worth trying?
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
