Hard water stains on granite countertops can be unsightly and sometimes stubborn to remove. But there is a solution!
Note that this procedure is for granite and quartz countertops only. It's important to test this method first on an inconspicuous place on your countertops.
The answer is a 50|50 solution of water and vinegar. Dampen a Magic Eraser with the mixture and gently rub the hard water stain with circular strokes for about five minutes. Rinse with water and wipe clean with a paper towel. Repeat as necessary. Customers tell us this works great! If the countertop turns dull, it may be time to reseal it.
