37 / 100

The anxiety of a new parent is intense. I just wanted to wrap him in a giant fluffy blanket for the first few months after my baby was born, and protect him from the big bad world. It can be a heavy burden for a first-time mom to feel that you are responsible for protecting this tiny little baby. Find out 10 Best Baby Bottle Sterilizers.

Parents often beat up worrying about what more could they have done to prevent their child from getting sick. I know I do whenever my child gets a sniffle or a fever.

It is really heart-breaking!

You’re not going to be able to protect your baby from everything out there, of course, but you can definitely take steps to ensure they don’t drink germs along with their milk. Having one of the best sterilizers for baby bottles will reduce some of your worries as a new parent.

Do I Need To Sterilize My Bottles?

Sterilizing bottles is just not a must, but it is a precaution that still many mothers choose to take.

It’s simple, and it cuts back into your baby’s regular introduction to the mountain of germs — and that’s always a good thing in my book.

I know I can’t wrap my kids in a bubble wrap and keep them safe from everything, but I think it’s worth it if sterilizing bottles stop even a single illness.

The first year a baby’s immune system is weak. It seems like germs are everywhere, when you’re a new parent, and there’s nothing you can do to avoid exposure— people love to touch and keep your child.

But since no one wants to be known as a paranoid mum who won’t let people near her child, you’re still left to ignore the inner voice telling you to look out for germs.

If you can’t stop all the germs that are spread by the masses of touchy-feely types around your baby, you can at least make sure his bottles don’t make him 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 mom’s sterilized bottles boiled them in water in a pan on the burner. The method is simple: make sure you thoroughly immerse each object in boiling water for at least 10 minutes.

This is cheap and relatively simple to do, although it may damage bottle nipples over a time, so be sure to check them once in a while for cracks.

While boiling is a perfect way of sterilizing, I have always avoided that. I use plastic bottles and I didn’t like the idea of boiling them because I wasn’t sure that when heated, harmful chemicals wouldn’t leach out.

2. UV Light

UV bottle sterilizers are one of the new sterilization methods, and use ultraviolet light to kill germs. Be prepared to pay dearly if you go along this path – these units cost many times what you would pay for an electric or microwave sterilizer.

Although they perform well, the price puts them out of reach for those of us who are unable to miss a payment for a car to purchase one.


  • 99.9 % of germs, viruses and bacteria are effectively killed.


  • It is expensive

3. Cold Water Sterilizing Solution

Method of this requires you to immerse the bottles and accessories in cold water where you have dissolved a bacteria-killing substance. Usually, the sterilizer comes in tablet form that dissolves and can be used to sanitize almost anything, not just bottles.


  • This method is very much affordable


  • A little Unfriendly for environment
  • Might not as thorough as other methods

4. Steaming

Times have changed since we were babies and today there is a more easy way of doing things. Now you can use steam to sterilize bottles as shown below, either with an electric steam sterilizer or a microwaveable one.

Microwave Steamers

These are very simple in design.

Fill with water, and put sterilizing steam in the microwave for a few minutes.


  • They are typically inexpensive and user friendly.
  • They can be taken on travels, and used wherever a microwave exists. 


  • They will scald you to pull them out when you reach into the microwave.
  • Some models may end up melting into more sensitive items.

Microwaveable steamer bags are still cheaper but may need a little more practice to use. All the same, they are the best choice for travel.

Electric Steamers

Plug in your bottles and sterilize them with a button press.


  • They’re more expensive than microwave sterilizers.
  • Some parents find them more detailed.
  • A couple of models come with a handy drying feature.


  • These types of sterilizers offer greater variation in size, quality, and design as you get a whole bottle sterilization appliance.
  • Larger units can hog the counter space in the kitchen.
  • You’d have to update them daily. If you live in a hard water place.

Choosing The Best Baby Bottle Sterilizers

I felt a bit like a nutty professor standing in my kitchen with rubber tongs in hand, looking down into a steaming bowl the first time I used a bottle sterilizer.

When you breastfeed, bacteria hardly have any chance of getting involved as the milk goes straight from you to your little one. But a little extra care is needed when introducing bottles to keep things sterile – even if that always seems like a challenge.

When buying a good electric steamer / sterilizer, here is what to look for:

Ease Of Use

Electric baby bottle sterilizers should be easy to use – if you find yourself scratching your head over the directions or the number of buttons, continue to find something more straightforward in your quest. 

The Size

You want to have the product large enough to fit all the bottles. Occasionally, mothers who breastfeed and only use bottles can get by with a small unit that holds only a few bottles.

How Many Bottles It Sterilizes At Once

Women who choose to feed their formula for babies will need to constantly sterilize bottles throughout the day. So they would want to search for a bigger sterilizer that can handle a greater number of bottles.

The Cost

If your cash flow is somewhat strained and now that you’re a mom, expense will be a big consideration. Microwave sterilizers tend to be cheaper on the market than other types.

Does It Dry

Microwave sterilizers work quickly, but the bottles are left wet, and after they are removed they will have to be cleaned, adding a further step to your workload.

Kitchen Space

Some moms may like microwave sterilizers should not need any space on their kitchen counters. They can be placed in a cabinet until you need them, and no outlet is needed to work. If you opt for an electric sterilizer, you will need to make some space for it on your table.

The Best Baby Bottle Sterilizers Of 2020

Keeping in mind that a sterilizer is mainly about keeping germs (and your paranoia) in control, you can feel highly assured that each time you use it, it will do its job.

Convenience, overall quality, performance and cost are also important factors, but at the end of the day those sparkling clean bottles you can happily give to your baby are what you want most. Here are the products which we believe can do just that.

Frequently Asked Questions

How Do I Use A Bottle Sterilizer?

You will be following different methods to get those perfectly clean, fresh bottles, depending on your sterilizer model. Next, wash it all in warm soapy water or a dishwasher. Then fill the sterilizer with clean bottles and add the corresponding amount of water to the machine.

For microwave sterilizers put the recommended time inside the microwave. Remove and allow bottles to cool inside, or use immediately, until they are needed. Clean, soft cotton. Hot. Let the steam dissipate to prevent burns, until reaching the microwave.

Switch the unit on for electric sterilizers, and let it work. If you have a model that dries too, wait until the drying process is complete. If left inside for 24 hours, most models will keep the bottles sterile.

When Can You Stop Sterilizing Bottles?

There’s no point in sterilizing bottles as soon as a baby is agile or tries to grab something (dirty) sees.

Remember If your child is old enough to make the idea that she can grab things and put them in her mouth, she will be exposed to more germs than her bottles could possibly contain.

But once you stop sterilizing, you should be sure to do a top-notch job of cleaning the bottles and nipples. And if your baby has a disease, then you should sterilize her bottles until she’s safe. You don’t want to reintroduce any germs into her immune system which recovers.

How Can You Clean/Descale A Sterilizer?

Your sterilizer would come using thorough cleaning instructions, but in general most removable parts of any unit can be washed with mild soap and water, while the rest can be cleaned with a damp cloth.

Limescale build-up on the sterilizer’s heating pad appears like a yellow or white discolouration. Using ordinary white vinegar or even lemon juice, this can be extracted at home: simply soak for 30 minutes to overnight and rinse well, followed by an empty cycle to release any residues.

Can I Use A Bottle Sterilizer For My Breast Pump?

Your special breast pump will have to come with washing instructions. Test these to see if bits of the breast pump can get into the dishwasher.

Use soap and water to wash any part that comes into contact with breast milk after you’ve finished using your pump. Allow dry air (drying cloths will add bacteria again) before it all reassembles, and you’re good to go.

Comprehensive home sterilization is not really feasible, but by simply cleaning, or using your bottle sterilizer (3), you can adequately sanitize breast pump parts.

Though, before you pop anything into your sterilizer, test both the sterilizer and the breast pump manual to ensure it’s clean. If you’re unsure or want to save the extra work, rest assured that there’s no need for daily sterilization and you can clean breast pump accessories with just soap and water.
