6. Maintenance
6.1 Cleaning and Sterilization
Proper cleaning and sterilization of pump parts are essential for hygiene and product longevity. The closed system design prevents backflow, protecting your milk.

- Motor Unit: Wipe clean with a damp cloth. Do not immerse in water.
- Other Parts (Flanges, Milk Collectors, Valves, Diaphragms): Disassemble all parts that come into contact with milk. Wash immediately after each use with warm soapy water. Rinse thoroughly.
