Pump Cleaning


How do I clean after each pumping? Do I need to clean the tubing by boiling in water or can i rinse it with warm water?


You dont need to sterlize or clean the tubing at all as the Lansinoh Signature Pro (and previous Affinity and Affinity Pro pumps also included) pump is a closed system pump and the milk does not come into contact at all with the tubing.  You can boil to sterilize the pump parts or you can put them through the dishwasher.  We recommend hand washing the valves as they are delicate.

If you have any more detailed questions, our customer service representatives will be happy to help via email at or via phone at 800 292 4794
