hard water stains

Calcium buildup marks

Hard water stains are the chalky white or cloudy deposits left behind when mineral-rich water evaporates.

The calcium and magnesium in hard water accumulate on faucets, showerheads, glass doors, and fixtures: The hard water stains on the shower door won't come off with regular soap.

Acidic cleaners like vinegar dissolve them.
