How do I clean the pump and its parts?
It’s important to clean breast pumps to keep breast milk free of microbes that may harm a baby. New pumps will provide cleaning instructions. If it is borrowed or rented, mothers may need to check the manufacturer’s website for specific information. After each use, the parts that come in contact with breast milk and the mother's body, including bottles, valves, and breast shields should be cleaned. This is generally done by rinsing each piece in cool water soon after pumping and then washing them using hot water, liquid dish soap, and a brush used only for pump parts. The pieces should be air-dried, reassembled, and safely stored. The inside of parts that come in contact with breast milk should not be touched. Depending on the pump, mothers may be able to wash the parts in a dishwasher.
