Best Baby Bottle Sterilizer 2020: When Your Baby’s Health is What Matters

For parents who want to make sure that their babies are safe and free from any toxins from the bottle, you should invest in the best baby bottle sterilizer that will help steam and remove the bacteria from it. But with the many types of sterilizers available, which one should you invest in? Read on as I show you the ultimate purchasing guide to the best baby bottle sterilizer to date.

What Are Baby Bottle Sterilizers?

Once your baby reaches the stage of using a baby bottle, then you’ll need to learn about the ways to properly clean it to get rid of any form of bacteria that may hide it. And while putting it in the dishwasher would be safe, it won’t exactly clean the bottle entirely.

That’s why there are methods on how you can properly sterilize the bottle to keep your baby safe from any form of hidden dirt that can cause sickness or allergies. While you’ll be able to clean your baby bottles through steaming them manually, it can be a hassle to do so.

This is where baby bottle sterilizers come to the rescue. These electric or microwave-safe sterilizers are containers you would use to steam bottles properly, without having to boil water or anything. You only microwave or let it heat up with the use of electricity, and it will be properly sterilized and stored for the day ahead.

The Benefits of Using Baby Bottle Sterilizers


You’re probably wondering: Isn’t it just enough to hand wash your baby’s bottles? Why bother sterilizing it? Here are some vital reasons as to why sterilizing baby bottles are essential for both you and the baby:

1. Safety

The main reason as to why parents sterilize baby bottles is because some harmful viruses or bacteria would still flow around the item despite washing it. And because babies are susceptible to many types of illnesses, even the smallest of bacteria found in the things they use can pose harm.With a sterilizer, you will be able to reduce the risk of illnesses, with the product killing up to 99.99% of bacteria.

2. Save Time and Hassle

If you have thought of sterilizing baby bottles before, you might be thinking about the amount of time and work wasted because of having to heat water and look for a container big enough to hold multiple bottles. A baby bottle sterilizer won’t only take a few minutes to complete sterilization, but it can hold more than two bottles, saving both time and effort on having to steam it yourself.

3. Multiple Accessories

Do you use a breast pump because of your milk flow lessening while breastfeeding your baby? Well, not only can the baby bottle sterilizer work for bottles, but you can also sterilize your breast pump to ensure bacteria-free milk flowing into the pump and the bottle or bag.

How to Use a Baby Bottle Sterilizer

How do you use a baby bottle sterilizer anyway? Here are the tips you should follow in sterilizing baby bottles with the use of steamers:

  • When you just purchased new bottles, be sure to wash and clean them before using it. For bottles that were just used, you should wash it before sterilization. Parents should take extra caution in sterilizing bottles of babies who were such to avoid re-infecting them with the same germs his bottle came in contact with.
  • To properly sterilize the bottles, follow the manufacturer’s instructions and place the bottles or equipment with the opening facing downward. This allows steam to sterilize the whole feeding gear.
  • Avoid overcrowding sterilizers, as this would end up either slowing down the sterilization process, or the equipment won’t be cleaned as properly.
  • If you plan on using a microwave sterilizer, then avoid overheating the bottles. It’s best to microwave it on high for the maximum time allowed. Be sure not to add anything metal in the microwave to avoid damage and accidents.
  • Don’t remove the lid until the bottles are completely sterilized. If you are storing it, you can keep it sterilized for until a day as long as you avoid leaving the lid open for extended periods.

How to Purchase the Best Baby Bottle Sterilizer

Now that you’re familiar with how baby bottle sterilizers work, the next question is how to buy the best one suitable for you and your baby. Here are some factors and tips to consider when doing so:

​1. Type of Sterilizer

There are three types to choose from:

  • Cold Water – These are soaked in a solution for half an hour and must be rinsed in boiling water before using it. It uses a cleaning solution, which gives a smell that your baby might not enjoy.
  • Microwave – They would kill bacteria from the heat it gets from microwaving, taking three to eight minutes to steam and sterilize properly. BUT, you cannot sterilize metal items, which aren’t allowed in the microwave.
  • Electric – There are no chemicals or rinsing that needs to be done. Plug the outlet in the wall and let it steam by itself, which would take six to 15 minutes. They are the most convenient way to sterilize if you have more bottles and equipment, or if you have no microwave.

2. Size

How many bottles of you plan on sterilizing per day? Some babies require as much as six to ten bottles a day, or you might have twins that need double that. Or if you use sippy cups and breast pump accessories, it’s best to find a bigger sterilizer that can fit all these items without worry of it breaking down.

3. Safety and Easy Features

I would recommend you to get a sterilizer with extra features that make sterilizing bottles and other baby equipment accessible and safer. Some sterilizers come with an alarm or automatic sterilization for less hassle, as well as water filters and other accessories that make it less of a hassle to clean and get the baby bottles out of the tray.
