How to Sterilize Medela Pump Supplies

If you choose to use a breast pump, either occasionally or exclusively, proper cleaning and sterilization of your pump supplies are critical for protecting your baby. The process of removing and storing breast milk for later use creates an opportunity for harmful bacteria, viruses and other germs to contaminate your baby's milk. Conditions such as thrush, increase the risk of contamination from dangerous germs. If you use one of Medela's breast pump kits, following the manufacturer's guidelines for sterilizing will ensure your expressed breast milk only contains the beneficial nutrients and antibodies your baby needs.

Things You'll Need

  • Pot
  • Distilled water
  • Medela Quick Clean Micro-Steam bag
  • Stove top autoclave

Instructions

    • 1

      Boil your pump supplies in a pot on the stove for 10 to 20 minutes using distilled water, if possible. Do not apply pressure on the outside of the supplies while sterilizing them, as this may damage the parts. Drain the water off and let them dry in the pot.

      Disinfect your pump supplies with a Medela Quick Clean Micro-Steam bag. Add water to the bag, place it in the microwave and run the microwave for three minutes. Reuse each bag up to 20 times.
