Boiling Instructions

• In a large pot, add enough water to cover all parts.

• Bring the water to a boil, then carefully add the disassembled parts.

Electric Sterilisers

• Fill the unit with water.

• Load the parts into the unit.

• Switch on and wait for the cycle to finish.

This is a quick and efficient option for your ‘how to clean breast pump parts’ problem. Especially for busy moms who have multiple feeds a day.

When to Sterilise

• Daily for newborns or if the baby is sick.

• Daily or after each use for preterm or immune-compromised babies.

• If using shared pumps, sterilise after each use.

• At least weekly for general upkeep.

Note: New parts of a breast pump should always be sanitised before first use.

 

Common Issues While Pumping and How to Solve Them

 

Cleaning the parts of a breast pump isn’t only about hygiene — it’s also key to functionality. Here’s how to troubleshoot:

Improving Suction

If your wearable pump isn’t working efficiently, it may simply be due to a buildup of loose parts of the breast pump. Reassemble properly, ensuring everything is dry.

Examine The Valves Or Membranes For Any Cracks Or Wear.

To prevent blockages that reduce suction, deep clean the valves at least once a week.

If possible, clean the pump tubing. If you are wondering how to clean breast pump tubing, ensure it is free from moisture or mold. Some pumps, including many available online, have closed systems, meaning the tubing doesn’t come in contact with the milk (but always double-check). 

Quick Cleaning Tips

• Have spare pump parts on hand so you’re not scrambling between cleanings.

• Label containers to distinguish between clean and dirty parts when travelling.

• Use disposable sterilising wipes in an emergency — but don’t rely on them as your everyday solution.

• Once dry, store the pump parts in a clean, breathable container.
