Cleaning quartz countertop

IDK if it’s from the housekeeper or from a product that was used by a guest but there are spray cloudy stains on my brand new quartz counter in the bathroom. Any idea how to get them off?

THANKS!

Have you tried a wet Magic Eraser sponge? It’s a mild abrasive and will remove residues that other methods leave behind. Was the quartz sealed?

It might be soap scum. Try using water with vinegar then quickly rinse with water.

Have you googled “cloudy stains on quartz countertops”? Polishing might help, but it’s could also be a chemical stains that is unfortunately permanent.
