Sterilisation

sterilising your pump & accessories

Keeping your breast pump clean and sterilised helps protect both you and your baby from bacteria and build up, and keeps your pump performing at its best.

Here’s a quick and simple guide you can follow at home.

Before first use:

Always sterilise all pump parts that come into contact with milk, including flanges, valves, membranes, bottles, and connectors.

Never sterilise the motor or electrical parts. Just wipe those gently with a clean, damp cloth.

After each use:

Rinse all used parts in cool water straight after pumping.
Wash them in warm, soapy water using a soft sponge or brush.
Rinse well and let them air-dry on a clean towel or drying rack.
Sterilise once a day (or more often if you prefer).

If you pump multiple times a day, rinse parts after each session and store them in a sealed container in the fridge between uses.

Then do a full wash and sterilise every 24 hours.

Drying and storing:

Always air-dry parts, don’t use cloths or tea towels.
Once dry, store in a clean, covered container or zip-lock bag until next use.
Avoid sealing damp parts (moisture encourages mould).
