Cleaning and Maintaining Your Wearable Breast Pump
Cleaning and Maintaining Your Wearable Breast Pump
When you’re relying on your breast pump every day, the last thing you want is a sneaky build-up of milk residue or a part that wears out sooner than expected. Keeping your wearable breast pump clean and well-maintained is key not only for your baby’s health, but also for ensuring the pump keeps doing its job efficiently.
Whether you’re new to pumping or a seasoned pro, this guide walks you through the essentials of cleaning, maintaining, and getting the most out of your Night Owl pump.
Why Cleaning Matters
Breast milk is packed with nutrients, which is wonderful for your little one but also means bacteria can grow quickly if parts aren’t cleaned properly. Regular cleaning:
Protects your baby from germs
Prevents milk build-up that can affect suction
Helps your pump last longer
Think of it as routine care for one of your most important parenting tools.
Step-by-Step: Cleaning Your Night Owl Pump
1. Disassemble after every use Remove all the parts that come into contact with breast milk (shields, valves, flanges, collection cups, and diaphragms)
2. Rinse in cold water first This helps stop protein in the milk from sticking to the surfaces.
3. Wash in warm soapy water Use mild dishwashing liquid and a dedicated brush or sponge (not the one you use for dinner plates).
4. Rinse thoroughly Running water is best, don’t just dunk the pieces in a sink of water.
5. Air dry completely Place parts on a clean, dry towel or a drying rack. Avoid cloths or tea towels that might hold bacteria.
Storage and Daily Habits
Keep it clean between pumps: If you’re pumping multiple times in a short period, store used parts in a clean, sealed container in the fridge between sessions. Then do a full wash at the end of the day.
Have a backup set of parts: This saves you stress on busy days and helps ensure you always have a clean set ready to go.
Dedicated cleaning station: Keep brushes, drying racks, and containers just for your pump and baby gear, no cross-contamination with family dishes.
Maintaining Your Pump for Long-Term Use
Even with the best care, some parts naturally wear down. Here’s what to look out for:
Valves: Replace every 4–6 weeks or sooner if suction drops.
Diaphragms: Replace every 6–8 weeks for hygiene and performance.
Flanges and shields: Check regularly for cracks, warping, or cloudiness.
Shield seals: Make sure they’re dry and free from condensation before reassembling.
Tip: Set a recurring reminder in your phone so you don’t lose track of part replacement schedules.
Common Mistakes to Avoid
Using harsh cleaners, bleach, or antibacterial sprays, these can damage the silicone and affect suction.
Submerging the motor, wipe the outside with a dry or slightly damp cloth only.
Skipping a full dry, moisture trapped in parts can cause mould or unpleasant odours, not to mention affect suction.
Ignoring small damage, tiny tears or loose fittings can quickly affect pumping performance.
Avoid drying cycles in sterilisation units, dishwashers, or other high-heat drying methods. These cycles can expose your pump parts to excessive heat, which may cause warping, hardening, or a loss of flexibility in silicone components.
Cleaning on the Go
For mums pumping at work, in the car, or while travelling, quick-clean wipes can make life easier. Just remember: these are temporary solutions. Always follow up with a thorough clean once you’re home.
Safety Reminders
Always wash your hands before handling pump parts.
Store expressed breast milk in clean, sterilised bottles or bags as recommended by health guidelines.
Don’t share breast pumps or parts between users, each pump is designed for personal use.
Your Night Owl wearable breast pump is designed to make life easier, but it does need a little TLC in return. With regular cleaning and timely part replacements, you’ll keep your pump running smoothly and your milk safe for bub.
