Quick Answer
Clean your eufy breast pump accessories after every use with warm, soapy water and air-dry on a clean towel. Replace the diaphragm, flange, and duckbill valves every 3 months, and the milk container every 3–6 months. Proper care prevents bacterial buildup and keeps suction strong.
Why Regular Cleaning Matters
Breast pump parts come into direct contact with milk, making them a prime spot for bacteria if not cleaned properly. Residue from milk fat can also clog valves and reduce suction over time. By sticking to a simple cleaning routine, you protect both your pump’s performance and your baby’s health.
When to Replace Parts
eufy recommends replacing the original diaphragm, flange, and duckbill valves every 3 months. The milk container should be swapped every 3 to 6 months. Using parts beyond these intervals can lead to decreased suction, leaking, or contamination. Setting a recurring reminder or using eufy’s Subscribe and Save option helps you stay on schedule.
Step-by-Step Cleaning Routine
- Disassemble All Parts: Separate the flange, duckbill valve, diaphragm, and milk container. Remove any milk residue from crevices. Checkpoint: Make sure the tiny duckbill valve flap is free of milk film — it’s easy to miss and can cause weak suction.
- Wash with Warm, Soapy Water: Use a mild dish soap and warm water. Scrub each part with a clean bottle brush, paying attention to the flange opening and valve seat. Checkpoint: Avoid using abrasive sponges that can scratch plastic and create hiding spots for bacteria.
- Rinse and Air-Dry Completely: Rinse all parts under running water to remove soap residue. Place them on a clean, lint-free towel and let them air-dry fully before reassembling. Checkpoint: Never reassemble wet parts — trapped moisture encourages mold and mildew growth.
- Inspect for Wear: Look for cracks, discoloration, or stretched silicone on the diaphragm and duckbill valve. Replace any part that shows signs of wear, even if it hasn’t been 3 months. Checkpoint: If the duckbill valve doesn’t close completely when you squeeze it, it’s time to replace it.
- Sanitize Weekly (Optional): For extra peace of mind, boil parts for 5 minutes or use a steam sterilizer once a week. Check manufacturer guidelines first — some parts may have temperature limits. Checkpoint: Silicone parts can degrade with repeated high heat, so limit sanitizing to once a week unless directed otherwise.
