Here’s how to wash your breast pump parts and baby bottles in the easiest possible (and safe!) way.
1. Take everything apart before washing
This might be obvious to experienced pumping moms, but I did not actually know I was supposed to take breast pump parts apart to clean them when I came home from the hospital. I just sort of kept them assembled and washed them the best that I could for the first week.
This isn’t how you are supposed to do it. Before you wash infant feeding items, take everything apart.
Note: You don’t need to wash your tubing every time. More on this here.
2. Use a wash basin and a dedicated bottle brush
The CDC recommends washing pump parts and bottles in a wash basin rather than directly in the sink in order to avoid contamination with any bacteria that might be there. They also recommend using a bottle brush that is only used for infant feeding items.
You can get a wash basin on amazon for less than $10. If you need one for washing pump parts at work, you may want to get a collapsible one.
3. Wash bottles and pump parts in hot soapy water
When you’re ready to wash everything, fill up your wash basin with hot, soapy water.
It’s important to use the bottle brush to get the soap on all of the parts (versus just soaking and rinsing). If you have breast pump parts that are a struggle to get to with your brush, try getting a set with smaller pieces like this one. They can be especially helpful for breast shield connectors.
4. Does your drying rack take up your whole counter? Make it vertical.
After you’re done washing your pump parts, you can set them out to air dry.
When I was exclusively pumping, bottles and pump parts took up my entire counter. If this is your current experience, you can make your drying rack vertical using a three tier cooling rack like this.

5. Use vinegar to get stubborn fat off of bottle nipples
Do you find that the nipples of your bottles are cloudy? Sometimes, breast milk fat residue can stick to them no matter how many times you wash them.
To get it off, you can submerge the nipples in a vinegar/water solution (10 parts water to 1 part white vinegar).
Soak them for 30 minutes, and then wash the nipples with soap and hot water.
6. Sterilize pump parts and bottles regularly
The CDC recommends sterilizing pump parts and bottles once a day for babies who are under three months old, who are sick, or who were premature.
If your baby doesn’t fall into one of these categories, it’s fine to sterilize a bit less often.
There are a bunch of ways that you can sterilize your infant feeding gear – a tabletop sterilizer, a microwave bag, boiling them, etc.
More information on each of these methods here.

7. Wash bottles and pump parts in batches
When you’re pumping 8-10 times per day, it can get exhausting to be constantly standing over the sink washing bottles and pump parts.
If you can, I would recommend getting a few extra sets of everything you need, and then washing them all at once.
In the past, I put breast pump parts in a zip-top plastic bag in the refrigerator between uses. However, the CDC now recommends washing pump parts in between each use. More info on this here.
8. Consider using your dishwasher to cut down on washing time
Another option to make the washing process easier is using the dishwasher to wash all of your gear.
Put infant feeding items on the top rack, and put smaller things like breast pump parts and nipples in a mesh bag (like this one) or other container. (Be sure to check your breast pump instruction manual to confirm that everything is dishwasher-safe.)

An added benefit of using the dishwasher is that if yours has a heated drying cycle, that will also take care of the sterilizing step.

Comments & Chitchat
How do you store your pump parts after sterilizing them? I have 5 sets and wash/sterilize the sets after each use. I have an oversupply and donate the excess milk to a milk bank so I’m trying to keep my pump parts as sterile as possible. Any suggestions would be great!
Hi Jillian! Let them air dry completely (if they aren’t already dry) and then store in a clean covered container (like Tupperware). Hope that helps!
Hi,
How do you store the parts and bottles before batch cleaning them? I have three sets of the parts.
Thanks
I would maybe just put them in your wash basin until it’s time to wash them?
Thank you for your response, unfortunately i dont have a bowl big enough as we have been in the process of renovation. But you think it will be ok to just wash all bottles and sippy cups with hot soapy water as long as I dont put them in the sink?
Hello so i usually wash bottles and feeding items in dishwasher but my dishwasher just broke, my question is do I need a wash basin or can i just wash under running water, with soap? Since my dishwasher broke suddenly i dont have a wash basin. Thank you for your time
That’s fine. As long as it doesn’t go in the sink. If you have a big bowl that will work too 🙂
Any recommendations on how to clean the tubing for the Medela pump in style ? The tubing takes forever to dry( even if washed the night before) ..
Hi Yeli! Have you tried attaching the tubing to the pump and running it without attaching it to pump parts? That works for some people!
I’ve tried the vinegar soak and the nipples are still cloudy. Is there any harm in still using the nipples? They have been washed and rinsed and sanitized. They’re just not nice and clear looking as when they first came.
Thank you!
Hi Lee, I would go ahead and use them! 🙂 I think it will be fine.
Are the cloudy nipples harmful to the baby? I just noticed they were cloudy. Not sure how long it’s been going on and the vinegar soak doesn’t seem to work.
Hi Lee, as long as you’re washing and sterilizing everything correctly, I don’t think the cloudy residue is harmful.
If I’m pumping 8-10 times a day how many extra sets would I need? 8-10 extra sets? Am I allowed to reuse any parts between sessions or use new sets each time? Sorry for the questions I’m currently pregnant and new to all of this.
I would probably get 4 sets and wash twice per day!
This article is super helpful- thank you! My question is how do you store the parts and bottles before batch cleaning them? I rinse and put in a tub of soapy water then put new hot soapy water in to wash. Is that safe?
I think that should be fine but I think you can just put them in the tub the first time as is, without adding soapy water? Just might save you a step. 🙂
Very helpful! The 3-tier cool rack idea is genius — thank you!
