Tested During Chaos: Are Comotomo Bottles Dishwasher Safe?

Picture this: Your baby is finally asleep. The sink is full. The dishwasher is running. You look at the Comotomo bottles on the counter and think — Can I toss these in, too?

Short answer? Yes, you can! But like most parenting things, there’s a little more to it.

I’ve used Comotomo bottles with both of my kids. They’re soft, simple, and baby-approved. And yes — they’re dishwasher safe… if you follow a few easy steps.

In this guide, I’ll walk you through it all — what parts are safe to wash, why the top rack matters, and the little tips that make life easier. I’ll also share how to fix cloudy silicone or weird smells (yep, it happens). Let’s make bottle-cleaning one less thing to worry about.

Quick Answer: Yes, Comotomo Bottles Are Dishwasher Safe

Yes — Comotomo bottles are safe to put in the dishwasher. I’ve done it many times, and they’ve held up great.

But here’s the trick: only use the top rack.

The top rack keeps the bottles away from the hot element below. That matters because high heat can bend or wear out the soft silicone. No one wants a warped bottle!

Comotomo says the same thing. All parts are safe for the dishwasher — if you load them right.

I always take the bottles apart first. That means the bottle, nipple, ring, and cap. Then I place the small parts in a mesh basket. That way, nothing gets lost or stuck.

When loaded this way, the dishwasher does a great job. It saves time and keeps your bottles clean and safe.

What Parts of the Comotomo Bottle Are Dishwasher Safe?

All parts of the Comotomo bottle are dishwasher safe — if you use the top rack. I’ve washed them many times with no trouble. Just make sure each part is placed right.

Here’s a quick look at each piece:

Part	Material	Dishwasher Safe?	Max Heat
Bottle Body	Silicone	Yes (top rack only)	Up to 180°C / 356°F
Nipple	Silicone	Yes	Up to 180°C / 356°F
Bottle Ring	Polypropylene (PP)	Yes	Up to 120°C / 248°F
Cap	Polypropylene (PP)	Yes	Up to 120°C / 248°F

Best part? These bottles are BPA-free, PVC-free, and phthalate-free. That means no harsh smells or risky stuff — just clean, baby-safe materials.

I put the bottle and nipple on the rack by themselves. The ring and cap go into a mesh basket. That way, nothing falls through or gets lost.

Why Top-Rack Placement Matters

So why use only the top rack?

Here’s the deal: Most dishwashers have a heating coil at the bottom. That area gets super hot. And heat like that can bend or damage silicone and plastic.

I learned this the hard way. One nipple slipped to the bottom and came out warped. It still worked — but not well. Since then, I stick to the top rack and use a basket for small parts.

The top rack stays cooler. It’s hot enough to clean, but not so hot it melts or ruins your bottle pieces.

With a little care and smart loading, your Comotomo bottles will last longer and stay in great shape.

Dishwasher Best Practices for Comotomo Bottles

Okay, so Comotomo bottles are dishwasher safe — but how you load them really matters.

Here’s what I do each time:

Step-by-step cleaning routine:

• Take everything apart: Unscrew the ring, remove the nipple, and pop off the cap. This helps each piece get fully clean.
• Use a mesh basket for small parts: The nipple, ring, and cap can fall through or block spray arms. I keep them in a basket so they stay in place.
• Place bottles upside down.: This lets water reach inside and drain out. I tuck the bottles between pegs on the top rack to keep them from tipping.

Do’s and Don’ts:

✅ Use the top rack only — always
✅ Run a rinse cycle if bottles sit dirty for a while
✅ Check the vents after each wash

❌ Don’t let nipples or caps get near the heating element
❌ Don’t crowd the rack
❌ Don’t use harsh or scented soap — stick to baby-safe, unscented ones

Watch for residue: Sometimes I see a bit of film or leftover suds. That’s usually soap buildup. When that happens, I rinse with hot water or soak the bottles in a mix of vinegar and water.

Common Issues & Easy Fixes

Even when you do everything right, little things can pop up. Here’s what I’ve run into — and how I fix them fast:

Cloudy or foggy bottles?

Totally normal. Silicone can look hazy after many washes, especially if you have hard water. It’s just a visual thing — the bottle is still safe.

Funky silicone smell?

Sometimes milk smells stick around. I get rid of that with a baking soda boil:

• Fill a pot with water
• Add 1–2 tablespoons of baking soda
• Boil bottles and nipples for 5–10 minutes

Smell gone!

Nipple collapsing during feeding?

Check the anti-colic vents. If they’re clogged, air can’t flow and the nipple caves in.

Comotomo Bottle Cleaning Options Compared

Wondering if the dishwasher is your best option? Here’s a quick side-by-side look:

Method	Pros	Cons	Best For
Dishwasher	Easy, quick, hands-off	Can cause heat damage if loaded wrong	Daily use, busy routines
Hand-wash	Gentle, no heat	Takes time, needs more scrubbing	Fast cleanups, deeper scrubs
Boil/Sterilize	Kills germs, great deep clean	May wear parts faster	First use, weekly deep clean

My routine?

I run bottles in the dishwasher daily and boil them once a week. If anything looks or smells off, I hand-wash with baking soda and a bottle brush.

It’s all about what works best for you — and your baby.

How Often Should You Replace Comotomo Bottle Parts?

Comotomo bottles are made to last — but not forever. I’ve learned to spot little signs when it’s time to switch parts. It’s helped me avoid leaks and late-night messes.

Here’s a quick guide:

• Nipples: Replace every 3 months
• Bottles: Replace every 6 months
• Rings and caps: Replace when they crack or feel loose

But don’t just count the months. Watch for these signs:

• The nipple collapses often (even after you clean the vents)
• You see tiny tears in the silicone
• The bottle feels sticky or turns deeply cloudy
• Any part leaks or doesn’t fit snugly

I once thought a nipple was fine — until I saw a tiny slit on the side. Milk spilled everywhere during a 2 a.m. feed. That’s when I learned: small damage can cause big trouble.

Comotomo’s silicone is strong, but not unbreakable. A quick check each month can save you stress — and laundry.

Final Thoughts: Is It Safe and Worth It?

If you’re like me, you’re always looking for ways to make bottle-feeding easier. Good news — using the dishwasher for Comotomo bottles is safe and saves time.

I’ve made it through newborn nights, cluster feeds, and those days when even washing a bottle feels hard. Tossing them in the dishwasher gave me a little break — and free hands when I needed them most.

Just follow a few simple steps. Use the top rack, take the bottles apart, and check the vents now and then. That’s all it takes to keep them clean and working well.

For me, it’s been 100% worth it. The bottles last, the clean-up is quick, and it’s one less thing to stress about.

Sometimes, the small wins really matter.
