How to Clean Medela Breast Pump Tubing

You've made the choice to breastfeed, and now you have to figure out how to clean your breast pump. Lucky for you, Medela breast pumps are designed to be easily used and cleaned. According to Medela, cleaning the tubing is not necessary, because it does not come into contact with your breast milk. However, a new nursing mother prefers to clean anything coming into contact with her baby, and breast pump tubing is no exception.

Disconnect the tubing from your Medela breast pump 1. Remove the end caps from the tubing, if necessary.

Boil half a pot of water, then place the tubing in the water for 10 to 20 minutes to sterilize.

Fill the syringe with rubbing alcohol. Position the head of the syringe at one end of the tubing. Hold the tubing so the opposite end is hanging in the kitchen or bathroom sink.

Flush the tubing with rubbing alcohol by dispensing the syringe. The rubbing alcohol will dry up excess water left in the tube from boiling.

Hang the tubing vertically to dry or use a hair dryer to remove any additional water. Hold the hair dryer about 1 to 2 inches from one end of the tubing to prevent melting.

Replace the end caps on the tubing prior to your next pumping session, if you removed them in Step 1.


Medela makes a microwave sterilizing bag to clean pump parts, including tubing. Run your Medela breast pump for a minute or two prior to pumping to remove any excess moisture in the tubing.
