In short: Rinse the milk system after each use, clean removable parts daily, and perform a thorough cleaning with milk system cleaner about once a week. Your machine's instructions are always the most important.
Why the milk system is so important
Milk leaves behind fat, protein, and milk stone in tubes, nozzles, and the frother. These residues dry quickly. The consequences: poorer milk foam, clogged nozzles, unpleasant odors, and a breeding ground for germs. This is why the milk system is the part of your coffee machine that needs the most care.
Cleaning schedule for the fully automatic coffee machine
| Component | How often? | What to do? |
|---|---|---|
| Milk system | After each use | Start the rinse program, wipe the nozzle |
| Milk container, tube, frother | Daily | Remove, clean with warm water and dishwashing liquid |
| Thorough milk system cleaning | About once a week | Cleaning program with milk system cleaner |
| Drip tray and coffee grounds container | Daily | Empty and rinse |
| Brewing unit | According to the manufacturer's instructions | Rinse or use a cleaning tablet |

If you use a lot of milk or milk sits in the system for longer periods, clean it more frequently.
Step-by-step: Thoroughly cleaning the milk system
- Preparation: Mix the milk system cleaner with water according to the instructions on the label.
- Filling: Pour the mixture into the milk container or a vessel and attach the milk tube.
- Start the cleaning program: Select milk system cleaning in your machine's menu and follow the instructions.
- Rinse: Then rinse with clear water so that no cleaner residue remains in the system.
- Clean parts: Disassemble removable parts, clean them, and let them dry.
If your machine does not have its own cleaning program, run the cleaning solution through the frother like milk and then rinse with clear water.
Typical mistakes
- Only rinsing the milk system in the evening or not at all – the residues dry out.
- Using descaler instead of milk system cleaner – descaler removes limescale, but not milk fat.
- Not rinsing with clear water after cleaning.
- Leaving milk in the container for hours without refrigeration.
- Forgetting seals and small parts when disassembling.
Safety
The milk system cleaner can irritate the skin and eyes. Wash your hands after use and keep it out of reach of children.

Frequently asked questions
How often do I need to clean the milk system?
Rinse after each use, clean removable parts daily, and perform a thorough cleaning with milk system cleaner about once a week.
Is the automatic rinse program enough?
Yes, for daily care. However, only regular cleaning with milk system cleaner removes dried-on fat and protein residues.
Can I put dishwashing liquid into the milk system?
Yes, for removable parts. You should only run products designed for the system through the system itself, and then rinse thoroughly with clear water.
Why is my milk foam no longer firm?
The nozzle or tube is often narrowed by milk residues. A thorough cleaning with milk system cleaner usually helps. Very hot or low-fat milk also froths poorly.
