What it means at home

- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?

Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
