How To Sterilize Breast Pump Parts (10 Easy Steps)

Breast pumping is a rewarding yet challenging task you take on to feed your babe the best milk there is, your milk. More importantly, sanitizing your pump parts keeps your milk safe and free from dangerous germs! So let’s get to it, here is how to sterilize breast pump parts in 10 easy steps.

I learned this simple method from my NICU (Neonatal Intensive Care Unit) nurses when my twin girls were born at 27 weeks. The items I share throughout this post I personally used and found to be super helpful. I am not endorsed by any of the brands I talk about. This is my experience to hopefully help you too!

1. To Sterilize Breast Pump Parts, Get Your Supplies Ready To Go!


You’ll need 7 things to get started…

These items were recommended by my NICU nurses that I personally used to clean and sterilize my breast pump parts.

Drying Mat or Towel

Whatever is your preference!

I use a drying mat to air dry my cleaned and sterilized pump parts.

Plastic Washing Basin

Make sure to clean your pump parts separately from the other dishes in your sink to keep it sanitary.

To do this, wash them in a plastic wash basin.

I used this one. I always had two on hand. One for washing and the other to put my pump parts in to dry. These basins are also great to use as a sensory bin when your kiddo gets bigger!

Baby Bottle Cleaning Brush

Use a bottle cleaning brush to thoroughly scrub down each pump part.

I believe this is the best brush for cleaning breast pump parts! Plus, you can pop it in the dishwasher to sanitize.

Medela Quick Clean Micro-Steam Bag

To quickly and easily sterilize breast pump parts, use a micro-steam bag.

Mild Dish Soap

No need to explain this one. 🙂

Measuring Cup

To measure 60 milliliters of sterile water (or 2 fluid ounces) to pour into your mico-steam bag, you’ll need a measuring cup.

Sterile Water or Distilled Water

Simply put, use ultra-clean water for optimal sterilization. This water is used to steam your pump pieces.

Now that your items are ready to go, here are the next steps to sterilize breast pump parts.

2. Rinse off your pump parts to remove any and all milk.


After you’re finished pumping, it’s time to clean and sterilize each piece.

I do this right in my kitchen sink. Run warm tap water to rinse off each of your pump parts to remove any and all milk.

3. Place your rinsed pump parts into a washing basin (or plastic bowl) with mild dish soap.


Squirt several large droplets of dish soap into a washing basin and mix it with warm water to create suds.

Then, place your rinsed breast pump parts into this bowl.

4. Clean each of your pump parts with a baby bottle cleaning brush.


This is the tedious part…cleaning breast pump parts!

If you’re pumping like a madhouse eight times or more a day, cleaning each pump piece feels like a new job. Am I right or am I right?

Nonetheless, be sure to scrub down each piece to remove any and all milk.

5. Rinse your cleaned pump parts under warm water.


For each pump piece you clean, run it under warm water. Then, place it right into a micro-steam bag.

6. Place pump parts into the Medela Quick Clean Micro-Steam Bag and seal it up.


A little trick I learned is to place your smaller pump pieces FIRST into the bag followed by your larger pieces.

Why?

When you dump the water from your bag, the smaller parts have a tendency of falling out and may go down your sink drain! To avoid this, keep your smaller pieces on the bottom and bigger pieces on top.

Make sure to seal up the bag.

7: Pour 60 milliliters (2 ounces) of sterile or distilled water into the Medela Quick Clean Micro-Steam Bag.

Use a measuring cup or bottle to pour 60ml (2 ounces) of sterile or distilled water into your steam bag.

8: Microwave for 90 seconds to sterilize breast pump parts.


When you steam your pump parts for this long, it kills 99.9% of nasty germs and bacteria.

Place the bag in the center of the turntable. If your microwave does not have a turntable, turn the bag halfway through the steaming process.

9: Remove water by pouring it out through the steam vent.


CAUTION: When you remove the steam bag from your microwave, be sure to grab it on the top right where it says “Hold here” and do NOT grab it on the top left where it says”Hot”.

I know this sounds self-explanatory…I mindlessly touched the bag where it says “Hot” (because I wasn’t paying attention) and burned my hand! It’s easy to do.

Just be sure to grab the bag correctly when you pour the water out. 🙂

For added protection, you may also wear oven mitts or hot pads to remove the bag from the microwave.

10: Dump out your pump parts on a towel or drying mat to air dry.


Since the pump parts are piping hot, they air dry quickly.

If you’re on a time crunch, you may also wipe down each piece with a paper towel.

Voila, that’s how you sterilize breast pump parts step-by-step!
