Take apart all milk-contact parts
After pumping, separate every part that touches milk — usually the flange, valve, membrane, and milk collector. These are the parts that need proper washing after each use.

How to Clean a Wearable Breast Pump Properly
Wearable pumps are designed to make life easier — but keeping them clean is just as important as choosing the right one. If you're still comparing options, you can explore our guide to the best wearable breast pump in Australia to better understand comfort, quiet operation, and everyday use.
A simple routine after each use helps protect your baby, keeps your pump working properly, and prevents issues later on.
This guide walks you through exactly how to clean a wearable breast pump, what actually needs washing, and the small mistakes most people don’t realise they’re making.
Why cleaning your pump properly matters
After each pumping session, a small amount of milk remains on the parts that come into contact with your skin and milk flow. If those parts aren’t cleaned properly, bacteria can grow quickly — especially in warm or damp environments.
That’s why cleaning isn’t just a routine — it’s part of safe feeding.
The good news is that it doesn’t need to be complicated. Once you understand what to clean and how often, it becomes a quick habit that fits naturally into your day.
With wearable pumps, the key difference is knowing which parts are washable and which are not. Getting that right makes everything much easier.
Simple step-by-step cleaning routine
You don’t need a complicated system. A consistent, simple process after each use is enough to keep everything clean and safe.
Rinse straight after use
Rinse each piece under running water as soon as possible. This helps remove milk residue before it dries and becomes harder to clean.
Wash with warm water and gentle soap
Use warm water and a mild dishwashing liquid to clean each part. Wash them separately to make sure nothing is missed.
Let everything air dry completely
Place the parts on a clean surface or drying rack and let them air dry fully. Avoid wiping them with a towel, as this can transfer bacteria.
What to clean (and what not to)
One of the most common mistakes with wearable pumps is treating every part the same. In reality, some parts should be washed every time, while others should never go near water. Understanding how each part works — including getting the right fit — also plays a role in comfort and performance. You can read our flange size guide to better understand how fit affects your pumping experience.
Clean all milk-contact parts after every use
Anything that touches milk should be cleaned after every session. This includes the parts that collect, seal, or guide the milk.
Keeping this consistent is the most important habit to build.
Never submerge the motor unit
The motor or electronic part of a wearable pump should never be washed or soaked.
If needed, simply wipe it gently with a clean, dry or slightly damp cloth.
Sanitise when you need extra protection
You don’t need to sanitise after every use, but doing it once a day can give extra peace of mind — especially in the early weeks or if your baby is more sensitive.
Check your pump’s instructions
Not every part can be boiled, steamed, or placed in a dishwasher.
If you’re unsure, always follow your pump’s specific care instructions to avoid damaging the parts.
Tubing may not need regular washing
If your pump includes tubing and it doesn’t come into contact with milk, it usually doesn’t need regular washing.
However, if you notice moisture or milk inside, it should be cleaned and dried properly or replaced.
Common mistakes to avoid
Most hygiene issues don’t come from not cleaning — they come from small habits that seem harmless.
Leaving parts sitting in the sink
It’s easy to leave parts soaking, but sinks can carry bacteria. It’s better to rinse and wash them properly straight away.
Reassembling parts before they are dry
If parts are still damp, moisture can build up inside. Always let everything dry completely before putting them back together.
Drying with a kitchen towel
Even clean towels can carry bacteria. Air drying is the safest option.
Only using wipes
Wipes are useful when you’re outside, but they shouldn’t replace proper washing with soap and water when you’re home.
Forgetting cleaning tools
If you use a brush or basin to clean pump parts, keep them clean too. These tools can collect bacteria if not rinsed and dried properly.
How to store pump parts after cleaning
Once your pump parts are fully dry, store them in a clean, dry place where they’re protected from dust and moisture.
Avoid sealing parts while they’re still damp, as this can trap moisture and lead to bacteria growth.
A simple routine works best:
- let parts air dry completely
- store them in a clean container or bag
- keep them separate from everyday kitchen items
Consistency matters more than complexity.
If you’re pumping at work, having a simple routine for cleaning and storing your pump parts can make daily use much easier. See our pumping at work guide for practical tips.
Choosing a pump that’s easy to clean matters too
Cleaning becomes part of your daily routine, so the design of your pump makes a real difference. Some wearable pumps have fewer parts, simpler assembly, and are much easier to manage over time.
