Living in a hard water area can be a pain; hard white deposits cling to your appliances and taps, and leave them struggling to do their job. Dishwashers suffer just the same, leaving your plates and cutlery not as sparkling as you’d hope. But to enjoy the Finish Diamond Standard make sure you follow our handy tips to banish hard water stains.

• Always use salt in your dishwasher to soften the water

If you follow these steps you’ll be guaranteed the Finish Diamond Standard, great performance from your dishwasher and reduced energy bills!
