How to clean and sanitize
breast pump parts

Why pump hygiene matters

Germs multiply in milk left on pump parts. Careful cleaning helps protect your milk. For babies born prematurely or with health concerns, a care team may recommend additional precautions. [1]

Before every pumping session

1. Wash hands. Use soap and water for 20 seconds.
2. Check your kit. Inspect and assemble clean parts.
3. Prepare shared equipment. Disinfect the pump’s controls and work surface. [2]

After every pumping session

1. Use suitable milk containers. Choose milk-storage bags or clean, food-grade containers with tight-fitting lids. [4]

   Seal, date, and time your milk; promptly refrigerate, freeze, or place in an ice-packed cooler.

2. Wipe the pumping area, especially shared controls and surfaces.
3. Separate and rinse every breast-contact or milk-contact part under running water.
4. Wash promptly after each use, following either method below. [2]

How to clean pump parts

By hand

1. Use a separate basin reserved for feeding items, with hot water and dish soap. Never place parts directly in the sink.
2. Scrub as the manufacturer directs, using a dedicated brush only if permitted.
3. Rinse under running water or in a separate basin of fresh water. [2]

In the dishwasher

Check that parts are dishwasher-safe. Secure small pieces in a closed basket or mesh bag. Use detergent and, when possible, hot water with heated drying or sanitizing. Unload with clean hands. [2]

Sanitize for extra protection

Sanitize at least daily for extra germ removal, especially for babies under 2 months, born prematurely, or with weakened immunity. Older, healthy babies may not need daily sanitizing if items are carefully cleaned after each use. [3]

Clean first, including the basin and brush. Use a method each item’s manufacturer permits.

Steam

Use a microwave or electric steam system as its manufacturer directs.

Boil

Disassemble boil-safe items and cover with water. Bring to a boil; boil 5 minutes. Remove with clean tongs.

Air-dry and store safely

1. Set clean items on an unused clean dish towel or paper towel, protected from dust. Allow to dry completely.
2. Do not rub or pat items dry with a dish towel.
3. Wash your hands, reassemble dry parts, and store in a clean, protected place. [3]

Handling pump tubing

• Correctly used tubing usually needs no routine washing.
• For condensation, detach tubing from the kit, leaving it connected to the pump; run until dry.
• Replace tubing containing milk or mold immediately. Check valves, membranes, and connections.
• Wipe a dirty exterior with a damp cloth or disinfectant wipe. [1]
