Cleaning Process

Cleaning Process^*

If you use a GROHE Blue system at home, we recommend cleaning it once a year, or every time you replace the filter, to keep your GROHE Blue working perfectly and delivering pure and delicious tasting water straight from the tap.

If the system is operated in the public/commercial sector (e.g. in a company’s kitchen or break room), a cleaning with the GROHE cleaning cartridge must take place twice a year (in accordance with DIN EN 6650).

Cleaning of GROHE Blue Home

Please order the GROHE cleaning cartridge for each cleaning cycle, and one time the re-useable cleaning adapter

Cleaning of GROHE Blue Professional

Please order the GROHE cleaning cartridge for each cleaning cycle.
The re-useable cleaning adapter comes already with the GROHE Blue Professional starter kit, but can also be purchased individually.

We also recommend that GROHE water system and filter are not left unused for a longer period of time.

What to do if you were away:
- from 2 days up to 4 weeks: the watersystem must be rinsed out with approx. 3 - 5 liters (depending on the size of the filter. For L size it is 6-7 liters. See also table in the printed instruction guide of the filter).
- more than 4 weeks: the filter must be replaced for hygienic reasons and the system should be cleaned with the GROHE cleaning cartridge.
