Do I Need to Sterilize My Bottles?

Sterilizing bottles isn’t a necessity, but it’s a step many mothers still choose to take.

It’s easy, and it cuts back on the mountain of germs your baby is introduced to daily — and that’s always a good thing in my book. I know I can’t wrap my children in bubble wrap and keep them safe from everything, but if sterilizing bottles prevents even one illness, I think it’s worth it.

A baby’s immune system is fragile for the first year. When you’re a new parent, it feels like germs are everywhere and there’s nothing you can do to avoid exposure — people love to touch and hold your baby. But since nobody likes being labeled a paranoid mommy who won’t let people around her baby, you’re often left ignoring that inner voice telling you to watch out for germs.

Germs everywhere

If you can’t stop all the germs caused by the hordes of touchy-feely types around your child, at least you can make sure her bottles aren’t making her sick.

Different Ways to Sterilize a Bottle

There are several ways to sterilize bottles and nipples, some easier than others.

1. Boiling

The way our moms sterilized bottles was to boil them in water on the stove in a pan. The method is simple: make sure you immerse each item thoroughly in boiling water for at least 10 minutes. This is cheap and relatively easy to do, although it can wear down bottle nipples with time, so be sure to check them for cracks once in a while.

While boiling is a perfectly good way to sterilize, I’ve always avoided it. I use plastic bottles, and I didn’t like the idea of boiling them because I wasn’t confident that harmful chemicals wouldn’t leach out when heated.

2. UV Light

UV bottle sterilizers are one of the newest methods for sterilization and use ultraviolet light to kill germs. If you go this route, be prepared to pay dearly – these units cost several times what you’d pay for an electric or microwave sterilizer. Though they work well, the cost puts them out of reach for those of us who aren’t prepared to skip a car payment to afford one.

3. Cold Water Sterilizing Solution

This method requires you to immerse your bottles and accessories in cold water in which you’ve dissolved a substance that will kill bacteria. The sterilizer usually comes in tablet form that dissolves and can be used to sanitize just about anything, not just bottles. This method is affordable but a little environmentally unfriendly and perhaps not as thorough as other methods.

4. Steaming

Times have changed since we were babies, and there are simpler way to do things today. You can now use steam to sterilize bottles, either with an electric steam sterilizer or a microwaveable one as shown below.

Microwave steamers are simple in design: fill with water and place in the microwave for a few minutes to generate sterilizing steam.

  • They’re typically cheap and easy to use.
  • They can be taken on trips and used anywhere there’s a microwave.

Electric steamers plug in and sterilize your bottles with the press of a button.

  • They’re pricier than microwave sterilizers.
  • Some parents find them more thorough.
  • A few models come with a handy drying function.

What Should I Look For When Buying?

The first time I used a bottle sterilizer I felt a bit like a nutty professor standing in my kitchen with rubber tongs in hand, looking down into a steaming bowl. When you breastfeed, there’s barely any chance for bacteria to get involved as the milk passes from you straight to your little one. But when bottles are introduced, a little extra care is needed to keep things sterile – even if that does feel like a mission sometimes.

Here’s what to look for when buying a good electric steamer/sterilizer:

  • Ease of use: Electric baby bottle sterilizers should be simple to operate – if you find yourself scratching your head over the instructions or the number of buttons, move on in your search to find something more straightforward.
  • The size: You want the unit to be large enough to fit all your bottles. Mothers who are breastfeeding and only use bottles occasionally can get by with a small unit that holds just a few bottles.
  • How many bottles it sterilizes at once: Women who opt to feed their babies formula will need to sterilize bottles frequently throughout the day. So they’ll want to look for a bigger sterilizer that can handle a larger number of bottles.
  • The cost: If your cash flow is a bit squeezed now that you’re a parent, cost will be an important consideration. Microwave sterilizers are usually cheaper than other types on the market.
  • Does it dry: Microwave sterilizers work quickly, but the bottles are left wet, and they’ll have to be dried after they’re taken out, adding an extra step to your workload.
  • Kitchen space: Some moms might like that microwave sterilizers won’t require any space on their kitchen counters. They can be stored in a cabinet until you need them and they don’t need an outlet to work. If you opt for an electric sterilizer, you’ll have to make some room on your counter for it.

The Best Baby Bottle Sterilizers of 2018

Keeping in mind that a sterilizer is primarily about keeping germs (and your paranoia) under control, you should feel supremely confident that it’s doing its job every time you use it. Convenience, overall size, efficiency and cost are important factors too, but at the end of the day what you most want is those sparkling clean bottles you can happily give to your baby. Here are the products we think can do just that.

1. Philips AVENT Microwave Steam Sterilizer

6. Medela Micro Steam Bags

Medela Quick Clean Micro-Steam Bags

If you have a tiny kitchen like mine, you may be loath to buy one more thing to try and cram into your cupboards. Plus, for the environmentally conscious among us, the idea of yet more plastic to eventually go into land fill may give you a pang of guilt you just don't need. A bottle steamer bag works just like those you use to steam vegetables in the microwave, only it's thicker and reusable.

7. Papablic Steam Sterilizer and Dryer

Papablic Baby Bottle Electric Steam Sterilizer and Dryer

Every mom's dream is to get all the millions of little jobs she has to do every day done in the blink of an eye. If you like the idea of a sterilizer that is truly all-in-one, look for one that steams but also dries your bottles, so you can just grab and go when the time comes.

This sterilizer is large and fits up to 11 bottles inside, and the internal trays can be reorganized depending on what you want to clean.

There are different settings, however, so you could also opt for a quicker sterilization cycle.


  • The sterilizer can handle very large loads.
  • Dries bottles thoroughly.
  • Just turn on and go with minimal fuss.

Frequently Asked Questions

Depending on your sterilizer model, you’ll follow different methods for getting those perfectly clean, fresh bottles. First, wash everything in warm soapy water or in the dishwasher. Next, load up the sterilizer with clean bottles and add the appropriate amount of water to the unit.

For microwave sterilizers, put inside the microwave for the recommended time. Remove and allow bottles to cool inside until they’re needed, or use immediately. Dry with a clean, soft cloth.

For electric sterilizers, turn the unit on and let it get to work. If you’ve got a model that also dries, wait for the drying cycle to complete. Most models will keep your bottles sterile if left inside for 24 hours.

There’s no point in sterilizing bottles once a baby becomes mobile or begins to grab at every (dirty) thing she sees (source).


When your child is old enough to make the connection that she can grab things and put them in her mouth, she’s going to be introduced to more germs than will possibly accumulate in her bottles.

After you stop sterilizing, though, you should be certain that you’re doing a top-notch job of cleaning the bottles and nipples. And if your baby has an illness (source), you should sterilize her bottles until she is healthy again. You don’t want to reintroduce any germs to her recovering immune system.

Your sterilizer will come with detailed cleaning instructions, but as a rule most removable parts of any unit can be washed with mild soap and water, while the rest can be wiped down with a damp cloth.

Limescale build up looks like a yellow or white discoloration on the sterilizer’s heating pad. This can be removed at home with ordinary white vinegar or even lemon juice: simply soak for 30 minutes to overnight and rinse off well, followed by an empty cycle to dislodge any residue.

Again, your specific breast pump will have come with instructions for cleaning. Check these to see if the breast pump parts can go into the dishwasher.

After you’re done using your pump, use soap and water to wash any part that’s come into contact with breast milk. Allow to air dry (drying cloths can introduce bacteria again) before reassembling everything, and you’re good to go. Thorough home sterilization isn’t really possible, but you can sanitize breast pump parts adequately by simply washing, or using your bottle sterilizer (source).

Before you pop anything into your sterilizer though, check the manual for both the sterilizer and the breast pump to ensure it’s safe. If you’re unsure or want to save yourself the extra work, rest assured that daily sterilization is not necessary and you can clean breast pump accessories with just soap and water.

The Bottom Line

The Philips AVENT Microwave Steam Sterilizer is a great pick for the price. It’s effective at eliminating germs, and it does it in just two minutes. This unit won’t need to be descaled like electric sterilizers do, and it doesn’t take up precious counter space which is important because, when you’re a parent, your baby’s gadgets seem to take up more room than your own do.

No electrical component of this machine will malfunction or break down, so you’ll always feel like you got your money’s worth with it. It’s a cinch to pack up and take with you on trips, unlike electric sterilizers which take up more room and have a lot of parts to keep track of. This unit will help you move full steam ahead in your quest to protect your baby.
