Why Cleaning Your Breast Pump is Important
Milk can stay inside parts of the pump. This can cause germs to grow. Germs can make your baby sick. Cleaning removes milk and germs from the pump. It also helps the pump work well. A clean pump lasts longer. So, cleaning is very important for you and your baby.
What You Need to Clean Your Medela Breast Pump
Before you start, gather these items:
- Warm water
- Mild dish soap
- Clean cloth or sponge
- Clean towel or drying rack
- Small brush (optional)
- White vinegar (optional)
Make sure your hands are clean before touching pump parts.
Parts of the Medela Breast Pump to Clean
You need to clean all parts that touch milk. These include:
- Breast shield (the part you put on your breast)
- Connector (the part that connects shield to bottle)
- Valve and membrane (small pieces that control milk flow)
- Bottle or container where milk collects
- Tubing (only if it gets wet inside)
Do not wash the pump motor or electrical parts. Only clean parts that hold milk.
Step-by-Step Guide to Clean Your Medela Breast Pump
Step 1: Disassemble The Pump Parts
Take apart all pieces that touch milk. This helps clean each part well. Be gentle to avoid breaking small parts.
Step 2: Rinse With Cold Water
Rinse each part with cold water. This removes milk residue. Use running water if possible. Do not use hot water yet.
Step 3: Wash With Warm Soapy Water
Fill a clean bowl with warm water. Add a small amount of mild dish soap. Use a clean cloth or sponge to wash parts. Clean inside and outside carefully.
If you have a small brush, use it to clean small parts. Be careful with the membrane; it is thin and fragile.
Step 4: Rinse Again With Warm Water
After washing, rinse all parts with warm water. Make sure no soap is left on them. Soap can harm your baby.
Step 5: Air Dry The Parts
Place parts on a clean towel or drying rack. Let them air dry completely. Do not use a towel to wipe them dry. This can add germs.
Step 6: Clean The Tubing (if Needed)
Check the tubing for milk or moisture inside. If dry, no cleaning is needed. If wet, clean tubing as follows:
- Fill tubing with warm soapy water.
- Shake gently to clean inside.
- Rinse with clean water.
- Hang tubing to dry completely before use.
Do not put tubing in dishwasher or washing machine.
Step 7: Sanitize The Parts
Sanitizing kills all germs on pump parts. You can do this once a day or as needed.
Two easy ways to sanitize:
- Boiling: Put pump parts in boiling water for 5 minutes. Use only parts that can handle heat.
- Steaming: Use a steam sterilizer or microwave steam bag. Follow instructions on the product.
Always check Medela’s guide to see which parts can be boiled or steamed.
Tips to Keep Your Medela Breast Pump Clean
