How to Clean and Maintain Mumflöw Breast Pump Parts

Quick answer

Clean your Mumflöw breast pump parts after every use with warm, soapy water, then air-dry. Replace valves and silicone diaphragms regularly to maintain suction and hygiene.

Step-by-step cleaning and maintenance

1. Disassemble all parts after each use: Separate the valve, silicone diaphragm, flange, collection cup, and any tubing. Rinse each piece under cool water to remove milk residue. Leaving parts assembled traps moisture and can lead to mold growth.
2. Wash with warm, soapy water: Use a mild dish soap and a dedicated bottle brush to clean every surface. Pay extra attention to the valve and diaphragm where milk fat can cling. Avoid abrasive sponges that can scratch silicone and create hiding spots for bacteria.
3. Rinse and air-dry thoroughly: Rinse all parts under clean running water, then place them on a clean drying rack or towel. Let them air-dry completely before reassembling. Do not use a dish towel to dry — it can transfer lint or bacteria. Patience with air-drying is key.
4. Sanitize weekly (or as needed): Boil parts in water for 5 minutes or use a steam sterilizer. Check manufacturer guidelines for your specific pump model; silicone parts are generally heat-safe. Over-sterilizing can accelerate wear on silicone diaphragms — once a week is usually sufficient.
5. Inspect and replace valves and diaphragms: Check for cracks, discoloration, or loss of shape in the silicone diaphragm and valve. If suction feels weak or milk flow slows, replace them promptly using a genuine replacement set. A worn diaphragm or valve is the most common cause of poor pump performance — keep spares on hand.
