How often do I have to disinfect my water ionier?
Disinfection is usually not necessary. Descaling with a warm citric acid solution also represents disinfection in itself.
For some applications, for example in commercial areas or in doctor's offices, it is definitely advisable to disinfect the spout by spraying and wiping with 10% hydrogen peroxide solution. This eliminates any germs that can be transmitted by touching the spout with bare hands. For particularly effective cleaning/disinfection, we recommend completely rinsing the device with 3,5% hydrogen peroxide solution. You can get these at the pharmacy.
