What Baby Bottle Sterilizer Should I Use

When I had my first baby, I was overwhelmed with the number of things I needed to prepare for their birth. Everything from burp cloths to baby monitors — there are so many products it’ll make your head spin. However, fast forward to today and a few kids later, I’ve learned how to separate the crucial products from the not so vital accessories. 

A baby bottle sterilizer, for instance, is invaluable for both mom and baby. I have found it to be one the most necessary things, whether you’re breast or bottle feeding, and thus recommend it to every mom I encounter. To learn more about what a baby bottle sterilizer does, and how to pick the best one for you, read on. 

 What is a Baby Bottle Sterilizer 

 How Does it Work? 

A baby bottle sanitizer ensures a deep clean every time you wash your bottles. They use steam to kill bacteria left behind from previous uses — which is optimal for newborns and premature children since their immune systems can still be weak after leaving the hospital. Sometimes a simple scrub in the sink isn’t enough. That’s where the power of steam comes in. Steam eliminates germs and bacteria by utilizing pressurized water that’s past its boiling point. This vapor loosens all of the leftover dirt and kills dangerous substances like mould, dust mites, and other allergens that could potentially harm your baby. 

 The Benefits of a Bottle Sterilizer 

While you can submerge your baby’s bottles in boiling water for the same effect, a bottle sanitizer is less wasteful and more convenient than heating up some water on the stove. You can also use your sterilizer to deep clean other baby products, such as toys, pacifiers, and teething rings. 

However, the most important benefit of using one is that your baby will be protected from bacteria and germs. And since sterilizers can clean multiple bottles at once, you’ll always have a fresh and clean bottle ready to go. These devices also work fast. For example, you can sanitize your bottles while your baby is napping, wait the allotted time, and have her bottle prepared before they wake up. 

Lastly, sterilizers are affordable accessories, making them more accessible to moms everywhere! You can also use one to clean breast pump parts if you’re pumping milk for your baby. Therefore, it’s one of my favorite multifunctional baby and mommy products out there. 

 Selecting the Best Sterilizer For You 

When selecting the best baby bottle sterilizer for you, take into account these next few things. Consider how many babies you have. For example, if you’re giving birth to twins, or have two babies under two, invest in a unit that’s large enough to suit multiple bottles for two or more children. 

Next, consider whether you want to invest in a microwave sterilizer or an automatic one. They vary in price points and work quite differently. I’ve had experience with using both and can say that I appreciated the ease and comfort of using an automatic sterilizer with my first child. However, by the time I had my second, I needed something that could clean toys for my toddler and bottles for my infant. A microwave sterilizer gave me the space to do so. 

 How to Use a Baby Bottle Sterilizer 

Most units work in the same way. However, make sure to always read the manufacturer’s instructions before using your sterilizer. If you’ve gone with an automatic steamer, make sure to run a few cycles with nothing inside of the canister first. This step cleans the unit properly before use. If purchasing a microwave sanitizer, run it through the dishwasher a couple of times before using it. When you’re ready to load up your baby bottles, wash them with mild soap and water first. Add water to the basin of your sterilizer or choice and start the cycle.

The Phillips AVENT Sterilizer works with nearly any microwave. It’s large enough to fit pacifiers, breast pump parts, and of course, bottles. You can sterilize all of your things in under two minutes, which already makes this easier than using a dishwasher.

Also, the latch on the unit is secure — so you can keep your items clean and out of the way until your baby needs to feed again. This is one of my personal favorites because of how large it is and how fast it works. When you have three kids, you need to make efficient use of your time. Thankfully, this sterilizer saves me a lot of it.

This item is even more convenient than using sterilizer bags — you’ll have more room to toss everything in at once. The bottom line is, it’s roomy, reliable, and includes a pair of tongs to make the whole sanitation process safer and seamless.

For the mom on a budget, the Munchkin Latch Sterilize Bags are a fantastic alternative to a steam sterilizer device.

Best of all, if you find yourself loving the steaming method, you can always upgrade to a full-sized device later on. But keep in mind that each bag is only meant to be used 30 times, so you may have to continuously repurchase them if you find these to your liking.

  •  Quick 90 second sterilize time


  • Bag is only reusable for up to 30 times  


While these are some great selections for moms out there seeking a great bottle sterilizer, the EIVOTOR 6 in 1 Double Bottle Baby Bottle Warmer is my number one pick.

Its auto-shutoff feature also ensures mom and baby’s safety. 

However, if you have multiple bottle-fed children, the Philips AVENT Microwave Steam Sterilizer may be a better choice because of its affordability and effectiveness. 

Using the right sterilizer can help in many different ways; you’ll spend less time worrying about whether your baby’s bottles are clean and ready to go for the next feed, and more time snuggled up next to your precious miracle.
