Why Cleaning Breast Pump Parts Properly Matters
Breast milk is packed with nutrients - and that means it's also an environment where bacteria can grow if your equipment isn't cleaned properly.
Regular cleaning ensures your milk stays safe for your baby and protects you from unwanted odors or residue buildup in your pump parts.
You don't need to deep clean every time you pump, but you do need a smart system that fits your workday rhythm.

How Often Should You Clean Pump Parts at Work
Ideally, you should clean your breast pump parts after each pumping session - but at work, that's not always realistic.
The CDC (Centers for Disease Control and Prevention) provides flexibility for working mothers:
- If you can't fully wash your pump between sessions, you can safely store the used parts in the refrigerator between pumps, then wash them thoroughly once you get home.
This method keeps your pump parts cold and prevents bacterial growth, making it a lifesaver for moms with back-to-back meetings or short breaks.

How to Clean Your Breast Pump Parts at Work: Different Methods!
- Rinse Immediately After Pumping
After each pumping break at work, quickly rinse the breast shields, valves, membranes, and bottles with cool or warm water. This prevents milk from drying and sticking.
💡 Pro tip: Keep a small water bottle or collapsible cup at your desk for quick rinsing if you don't have easy sink access.
- Store Pump Parts in a Sealed Container
Once rinsed, place the parts in a clean zip bag, wet bag, or plastic container with a lid.
If you have access to a fridge, keep the bag inside to slow bacterial growth. If not, use an insulated cooler with an ice pack - like the new 4AllFamily breast milk cooler, which also doubles as a safe space for pump parts between sessions.
- Wash Thoroughly When Possible
When you have time and access to a sink, wash each pump part in warm, soapy water using a dedicated brush or sponge. Rinse thoroughly under running water, and place pump parts on a clean paper towel or a drying mat to air dry.
🚫 Avoid setting them directly on work surfaces or using cloth towels, which can carry bacteria.
If your workplace has a staff kitchen or lactation room, keep a small pump cleaning kit there for convenience.
- Use Pump Wipes or Sanitizing Spray When a Sink Isn't Available
If you can't wash immediately, use breast pump cleaning wipes (like Medela or Babyganics) or a food-grade sanitizing spray.
These wipes are designed specifically for breast pump parts and are safe for milk contact - just let the parts air-dry before reassembling.

- Air-Dry Completely
Moisture encourages bacteria. Always let your pump parts air-dry on a clean paper towel or drying rack, not inside a bag or closed container.
If you're using the "store-in-the-fridge" method, allow them to dry completely at home after washing.
Cleaning Options by Workplace Setup
✅ If You Have a Lactation Room at Work
You're in luck! Set up a small cleaning station with:
- Mini dish soap
- Bottle brush
- Drying rack or mat
- Clean paper towels
- Spare parts in a labeled box
You can wash parts right after each pumping session and leave them to dry while you teach, work, or attend meetings.
✅ If You Work in a Classroom or Shared Office
Teachers and open-plan employees often have less privacy. Here's what works best:
- Use pump wipes or sanitizing spray after each session.
- Store parts in a cooler bag with ice packs between sessions.
- Do a full wash at home in the evening with warm water and soap.
4AllFamily's breast milk cooler can keep your milk and parts at a safe refrigerator temperature (2-8°C) for up to 24 hours - no office fridge needed.

- Pack disposable pump wipes for quick clean-ups.
- Bring a compact cooler to hold your milk and parts.
- Rinse everything once you're home.
The key is organization - keeping everything in one clean, easy-to-carry bag saves time and stress.
✅ If You Share the Workspace
If your workplace has a shared lactation or staff room:
- Use labeled containers for your items.
- Disinfect surfaces before and after use.
- Respect other moms' pumping times - a little kindness goes a long way.
