Proper cleaning and sterilisation are essential to prevent bacterial contamination and ensure the pump remains in top working condition. Here’s a comprehensive guide to help you keep your breast pump clean and sterile.
Why Clean and Sterilise Your Breast Pump?
Breast pumps come into contact with your breast milk, which can be a potential breeding ground for bacteria if not cleaned properly. Regular cleaning and sterilisation prevent milk residue buildup and bacterial growth, protecting your baby from potential infections.
Materials You’ll Need
- Clean, hot water
- Mild dish soap (preferably unscented)
- Bottle brush (for scrubbing)
- Small brush (for cleaning small parts)
- Clean, dry cloth or paper towels
- Boiling water or sterilizer (steam or electric)
- Breast pump parts and accessories
Step-by-Step Cleaning and Sterilising
Prepare Your Work Area
Start by washing your hands thoroughly with soap and water. Make sure your cleaning area is clean and free from contaminants. Lay out all the parts of your breast pump and any cleaning tools you’ll need.
Disassemble the Breast Pump
Carefully take apart all the components of your breast pump, including:
- Flanges
- Valves
- Diaphragm
- Milk collector
- Pump motor (place to the side)
Check the manufacturer’s instructions for any specific disassembly recommendations.
Wash the Parts
Fill a basin with hot, soapy water. Use a mild, unscented dish soap. Submerge the disassembled parts and use a bottle brush to scrub them thoroughly. Pay special attention to any areas where milk residue might accumulate, such as the inside of the flanges and bottles. Use a small brush to clean hard-to-reach areas, like valve openings.
Rinse Thoroughly
Rinse all parts under running hot water to remove any soap residue. Make sure no soap or milk residue remains, as this can affect your milk’s taste and quality.
Dry the Parts
Place the cleaned parts on a clean, dry cloth or paper towels to air dry. Ensure they are completely dry before reassembling. Avoid using a dish towel that may harbor bacteria.
