How to clean and sterilise your Wren Breast Pump
Washing and caring for your pump will see it through countless expression sessions to come. Here are our tried and tested tips for looking after your pump parts.
How often should I sterilise my pump?
Different parts of your pump will need different types of love. While the motor shouldn’t ever be submerged in water, it can be wiped clean with a damp cloth to keep it fresh.
The parts that come into contact with your breast or breast milk will need a bit more TLC however, as they run more risk of harbouring harmful bacteria that could lead to a nasty infection for your baby.
The washable parts that will need attention are:
- Silicone breast shield
- Breast adaptors
- Diaphragm
- Valve
- Connector unit
- Seal ring
- Collection bottle.
How often you sterilise is really up to you and will depend on your usage although we recommend giving everything a rinse and a wash and sterilising after each use
How to sterilise your hands-free breast pump
Before you use your pump for the first time, clean, sterilise and dry all the washable parts.
Thereafter, after each use:
- Rinse the parts in cold, clean water.
- Give them all a wash in warm water with a mild washing-up liquid.
- Rinse them with cold water a second time.
To sterilise the pump parts, either:
- Boil the parts in hot water for 2-3 minutes, OR
- Submerge them in cold water for fifteen minutes with a sterilising tablet or liquid such as Milton.
Use the bottle brush in your kit to wash out the bottles. Keep this brush just for your pump parts, rather than contaminating it by using it for other jobs.
Let the whole lot air dry before reassembling your pump, or use a clean, dry towel to daub the parts down. It’s not a good idea to assemble your pump when the parts are wet, or it could encourage mould to form.
Can I clean breast pump parts in the dishwasher or microwave?
While you can put parts in the dishwasher to clean them, this will not sterilise them, so you may prefer to wash everything by hand to ensure it’s all completely clean.
If you have a dishwasher with a hot, steam-drying function, parts may deteriorate more quickly and need replacing. We don’t recommend steaming parts as high temperatures could warp or damage the plastic.
We don’t recommend sterilising parts in the microwave or any system that involves hot steam as this will cause them to degrade faster.
Where can I buy replacement parts for my Wren breast pump?
Over time, and with regular use, the parts of your pump may start to wear and tear. We recommend changing these every 2- 3 months. The good news is, we have replacements covered in our online spare parts shop, all at an affordable price.
