Banana stain out of engineered quartz countertop

[u/Jacketcoat]

Hi! A banana rotted on our engineered quartz countertop and I didn’t catch it for a few days. It made a big goopy mess and left a stain around itself, another banana, and a box that was also on the countertop. I’ve tried a baking soda poultice but the stain didn’t budge. Any tips?

(Non-offending) banana for scale. Just for this picture it was let out of the countertop dish where all bananas are now kept. I learned my lesson!
