FAQ
How do I know if I have hard water?
Look for cloudy glasses, white spots, chalky residue on dishes, or limescale in your dishwasher. You can also buy a simple hard water test kit at most stores.
What’s the best way to beat hard water?
Choose a dishwasher with a built-in softener, or always use a rinse aid and clean your machine monthly with a descaler tablet.
