Momcozy M5 Dishwasher Safe? What You Need to Know

The first time I used the Momcozy M5, I felt two things—excited and confused. It was hands-free, small, and so much easier than the big, noisy pumps I used before. But when it was time to clean it? That’s where I got stuck.

I stood at the sink, holding what felt like a dozen tiny parts, asking myself:
“Can I just throw all this in the dishwasher?”

Spoiler: Not exactly.

Here’s the thing—when you’re pumping many times a day, cleaning isn’t just about saving time. It keeps your milk safe, your baby healthy, and your pump working right. One stretched ring or trapped drop of water can cause big problems fast.

I’ve been there—late at night, scrubbing tiny parts, searching how to dry tubing without mold, and learning the hard way what melts in high heat.

So, I made this guide. To help other moms like me know what’s safe, what Momcozy says, and what actually works. Let’s dive in.

Quick Answer: Is the Momcozy M5 Dishwasher Safe?

Short answer? Some parts are—but not all. When I first got the M5, I asked the same thing:
“Can I toss it all in the dishwasher and call it a day?”
I wish it were that simple.

After reading the manual, testing it, and chatting with other moms, here’s what I found:

Dishwasher-Safe Parts (Top Rack Only)

• Collection cups
• Flanges (the part that touches your breast)
• Valve bases
• Milk containers
• Duckbill valves

These are all made from safe plastic or silicone. I’ve washed them on the top rack using a gentle cycle—no warping, no damage.

Not Dishwasher-Safe

• The motor (never wash—just wipe it down)
• Tubing (can trap water inside)
• Silicone inserts and sealing rings (may stretch or lose shape)

Use a mesh dishwasher bag for small parts. That keeps them from melting or getting lost. And always use the top rack. The bottom gets too hot and may warp parts over time.

What Momcozy Says About Cleaning the M5

Momcozy says some parts of the M5 are dishwasher safe—but only on the top rack.

Sounds clear, right? Not really.

Here’s what they actually say:

• “All washable parts (excluding the motor) can be cleaned using warm water and mild detergent.”
• “Top rack dishwasher safe” is listed for some plastic parts.
• “Do not boil silicone inserts too frequently as it may reduce their shape and function.”

So yes, some pieces can go on the top rack—but they don’t clearly list which ones.

The confusing part? The soft silicone inserts and seals.

Momcozy doesn’t say, “Don’t put these in the dishwasher.” But they hint that heat can damage them. I tried it once—and the insert came out stretched. That was enough for me.

What Momcozy Recommends (Plain and Simple):

• Wash every part that touches milk after each use.
• Hand wash or top-rack only for hard plastic parts.
• Avoid harsh soap, hot water, or rough scrubbing.
• Wipe the motor with a clean, damp cloth only.

What I Actually Do

Let’s be honest—if you pump three times a day, cleaning can’t take forever.

I’ve tried a lot of things. Here’s what works best for me without damaging parts.

My Real-Life Cleaning Routine

After each session:

• I rinse every part that touches milk with warm water.
• I hand wash the soft parts like silicone inserts and duckbill valves using a bottle brush.
• I toss the collection cups and flanges into the dishwasher every other day—top rack, gentle cycle only.

What I Hand Wash Daily

• Silicone inserts
• Duckbill valves
• Seals and soft rings

Why? Because heat can stretch or bend them. Once the seal is weak, you’ll feel it right away.

Drying + Storing Tips

• I air dry parts on a clean bottle rack with space in between.
• I don’t use towels (they leave lint).
• I let everything dry fully before storing.
• Every few days, I sanitize parts using a steam bag or boiling water—but not the soft silicone.

Tips for Washing Breast Pump Parts Safely

If you’re like me, you want cleaning to be quick, safe, and not wreck your gear. Over time, I picked up a few tricks that help me clean fast and keep parts in good shape.

Smart Cleaning Tips for Busy Moms

• Rinse right away. Don’t let milk sit. It gets sticky fast.
• Use warm, soapy water and a soft brush to clean each day.
• Clean in good light. Helps you see buildup in corners and valves.
• Use a mesh bag in the dishwasher for small parts—lifesaver.
• Top rack only. Pick a gentle cycle if using the dishwasher.

What Not to Do

• Don’t boil soft silicone parts often. I did this and they went floppy.
• Avoid hot cycles like “sanitize.” That’s what stretched my inserts.
• Skip rough sponges. They scratch plastic and hold milk film.

Cleaning Hacks I Swear By

• A thin, soft bottle brush is perfect for duckbill valves and tubing.
• Use a drying rack just for pump parts. It keeps things clean and neat.
• For deep cleaning, I soak parts in warm water with a drop of baby-safe soap for 10 minutes, then rinse well.

Keeping it simple has saved me time—and I haven’t ruined a part since.

Is Dishwasher Use Safe for Baby’s Health?

This was a big question for me early on. Cleaning well isn’t just about your pump—it’s about your baby’s health too.

Dishwasher Cleaning vs. Sterilizing

Yes, dishwashers clean, but they don’t always sterilize. That’s a big difference.

• Most dishwashers don’t get hot enough to kill all germs.
• If parts stay wet, mold or mildew can grow—especially in tubing.

What the CDC Says

The CDC says:

• Wash pump parts after each use.
• Sterilize at least once a day if your baby is under 3 months, born early, or has a weak immune system.

Ways to safely sterilize:

• Steam bags in the microwave (fast and easy)
• Boiling water for 5 minutes (not for soft parts too often)
• Electric sterilizers work great if you want a hands-off option

Just because something is “dishwasher-safe” doesn’t mean it’s fully clean or germ-free after one wash.

I use the dishwasher to save time, but I still sanitize every few days—especially when my baby was a newborn. It gave me peace of mind.

Final Thoughts: What I Recommend to Other Moms

If you’re using the Momcozy M5 every day, here’s what I’ve learned:
You don’t have to do it all perfectly. Just find a routine that works.

Here’s What Matters Most

• Wash parts that touch milk right after each session.
• Hand wash soft parts to avoid damage.
• Use the dishwasher for hard plastic, but only on the top rack.

My Real-Life Take

There’s no single “right” way. Some days I hand wash every piece. Other days, I toss stuff in a mesh bag and run a quick wash before bed.

If you’re not sure what’s safe? Hand wash. It’s the safer choice.

Being a mom is already a lot. You don’t need to be perfect—you just need to be consistent.
