Water Stains On Quartz Countertops. Quartz countertops are top-shelf surfaces but are marketed as if they cannot etch or be stained.

Sealing is vital as it creates a barrier of protection around your natural stone. A traditional stain occurs when some substance absorbs creating a dark spot. Quartz countertop stains occur due to a chemical reaction with the resins used to make the countertop.
Once you are done rinse it with fresh water and dry the countertops with a towel.
Create a baking soda paste apply it to the hard water stain and gently scrub it with a soft bristle brush. If the water beads up then your seal is probably going strong. The stone will dry out all on its own. If this is a moisture problem a plumber will need to identify the source of moisture and resolve the moisture problem first.
