Keeping your breast pump clean goes a long way toward keeping your breastmilk safe and your equipment working as it should.
Here’s how to keep your pump squeaky clean and in tip-top shape in just a few easy steps. Before you begin, you’ll want to check the cleaning instructions in your pump’s manual to confirm which parts are dishwasher-safe.
Washing Your Breast Pump by Hand
- Wash your hands well with soap and water for 20 seconds.
- Place pump parts in a clean basin used only for baby feeding items — not directly in the sink
- Add soap and hot water
- Scrub all hard plastic/silicone pieces reserved only for pump parts Note: Wash the valves and diaphragms by hand only; do not use any kind of brush.
- Rinse under running water or in a separate basin of fresh water
- Air dry thoroughly on a clean towel — never rub or pat dry with a dish towel
Washing Your Breast Pump in the Dishwasher
- Place small parts in a closed-top basket or mesh laundry bag
- Add soap and run on hot water with a heated dry or sanitizing cycle
- Remove with clean hands and air dry completely before storing
Sanitize Regularly for Extra Protection
For an extra step of protection, sanitize pump parts, your wash basin, and bottle brush regularly using steam, boiling water, or in the dishwasher. Check your pump's instructions about whether items can be steamed or boiled.
- Clean pump parts, bottle brushes, and wash basins before they are sanitized.
- Sanitize the pump kit, bottle brushes, and wash basins using one of the following options:
- Steam: using a microwave or a plug-in steam system, follow the manufacturer's directions.
- Boil: add parts that are safe to boil into a pot and cover with water. Boil for 5 minutes and remove items with clean tongs.
Place sanitized pump parts, wash basin, and bottle brush on a clean, unused dish towel or paper towel in a clean, protected area. Do not use a dish towel to rub or pat dry to avoid introducing germs.
