It is impossible to completely sterilize your breast pump at
home. Some hospitals offer free or fee-based sterilization
services using an autoclave meant for sterilizing reusable surgical
tools and hospital equipment.
Not even boiling them at home will completely sterilize breast pump
parts. However, you can keep your breast pump safe and sanitary
by effectively washing away germs and bacteria after each use.
General Tips for Cleaning Your Breast Pump
Consult the instruction manual included with your breast pump for the
manufacturer-recommend method of cleaning. Keep in mind that not
all pieces of a breast pump are meant to be washed. Electrical
units and batteries should be wiped down after use, but never
submerged in water.
Typically, a pump must be taken apart before appropriate pieces are
washed. Most washable pump pieces can be cleaned by hand using
soap and hot water. Some pumps can be put in the
dishwasher. Consult your instruction manual to make sure pieces
are dishwasher safe before you put them in the dishwasher.
Basic Cleaning Method
Take apart the pump. Consult the instruction manual to determine
which parts should be washed.
Wash each piece separately using liquid dishwashing soap and plenty of
warm water.
Rinse each piece thoroughly with hot water for 10 -15 seconds.
Place the pieces neatly on a clean paper towel or in a clean drying
rack and allow them to air dry.
Avoid using a cloth towel to dry your pump because they can carry
germs and bacteria that are harmful to your breast milk and your baby.
Once the pump is dry, assemble it before storing.
Try not to touch the inside of any parts that will come in contact
with your milk the next time you pump.
