Types of Baby Bottle Sterilizers

There are 3 main types of bottle sterilizers:

  1. Electric Steam Sterilizers
  2. Microwave Steam Sterilizers
  3. Cold Water Sterilizers

Each different type has its own pros and cons. We shall take a look at them in turn now.

Electric Steam Sterilizers

With most electric steam sterilizers, you simply need to place the bottles in upside down and add water. After around 10 minutes the sterilization process will be complete. Most of these sterilizers will sound an audible alarm and shut-down automatically. Providing the bottles aren’t removed, they’re kept sterile for up to 6 hours.

  • Easy to use.
  • Efficiently Kills 99.9% of germs.
  • Quick at under 10 minutes.
  • No prep time needed.


  • Most expensive type of bottle sterilizer.
  • The inside of the unit can get hot enough to burn hands.
  • Need for descaling.

Microwave Steam Sterilizers

The bottles are placed in the microwave sterilizer unit and a small amount of water added. It’s important to ensure the lids are all on tight before putting inside the microwave. From there, you need to follow the manufacturer’s guidelines, but the sterilization again takes around 10 minutes.


  • Convenient & can sterilize with your existing microwave.
  • Space Saving.
  • Fast and Simple.
  • Relatively Cheap.


  • Some sterilizers only fit 4 bottles.
  • Some are too big for smaller microwaves.
  • A burn risk from the hot water inside the sterilizer.

Cold Water Sterilizers 

Cold water sterilizers (a.k.a “Chemical Sterilization”) may sound the least effective of the three, but they are used in hospitals to sterilize baby bottles. This method uses sterilizing tablets or a special liquid that is mixed with cold water in the sterilizer’s tank. The liquid contains a form of diluted bleach. The baby bottles are then completely

This method uses sterilizing tablets or a special liquid that is mixed with cold water in the sterilizer’s tank. The liquid contains a form of diluted bleach. The baby bottles are then completely submerged in the solution.

Great care needs to be taken that there are no air bubbles created. Bacteria and germs can survive inside the bubbles. You need to be especially careful when the bottles are lying on their side.

The cold water process takes about 30 minutes. Once completed, the bottles need to be rinsed out completely in hot, boiling water. Ensure that there’s no sterilizing solution left on the bottle.


  • No burn risk as no heat required.
  • Suitable when traveling as doesn’t need electricity.
  • Bottles are still sterile when you open the lid.
  • Lower carbon footprint.


  • The Solution needs changing every 24 hours.
  • Up to 3 times slower than the Electric / Microwave method.
  • The bottles, solution,  and sterilizer are heavy to move when filled.

The Boiling Water Method

If you don’t want a baby bottle sterilizer or are only sterilizing the occasional bottle, the boiling water method could be appropriate for you. It’s cheap, effective and relatively quick.

To sterilize a bottle in boiling water, you need to set aside a dedicated pot or pan for this task alone. First, place the feeding accessories to be sterilized into a boiling pot or pan of water. Then, bring the water back to the boil and let simmer for 10 minutes. Remove all the items afterward with a pair of metal tongs.


  • Quick – Almost the same time as the electric steam method.
  • Easy – Just like boiling an egg!
  • Cheap: No need to buy a sterilizer, just a cheap pot or pan.


  • Rubber teats can become swollen and spongy through boiling.
  • You need a big, dedicated saucepan.
  • Increased risks of burns.

You need to put the bottles somewhere to dry off.

Do you really need a bottle sterilizer?

There is a lot of debate among pediatricians and parents whether a baby bottle sterilizer is all that necessary nowadays. Many people regard them as left-overs from our grand-parents and parents generation when hygiene standards weren’t as high as today.

The argument goes that as long as your drinking water is safe to drink, you can get away with washing bottles in hot, soapy water. This also assumes that you follow a rigorous handwashing regimen too. The FDA found that many parents forgot to wash their hands after changing diapers,

The FDA found that many parents forgot to wash their hands after changing diapers, petting cats and dogs and handling raw meat. With or without a bottle sterilizer, this is essential advice.

Do I have a bottle sterilizer?

Yes, I do. An electric steam one. And here’s why.

When you have your first baby, you’ll know that parents and grandparents provide a lot of support. It can be a bit smothering at times! They might not understand your decision to forgo a bottle sterilizer.

You can also bet that if your newborn becomes sick, the fingers will be pointing at where the bottle sterilizer should be. And those fingers are usually attached to the in-laws…For around $30 you can get a top rated bottle sterilizer and reduce the risk of bacterial infection. A lot less hassle in the long run!

I have to say though after reviewing the evidence, the hot water method does seem safe enough. We just enjoy the convenience and peace-of-mind of using our sterilizer. Plus, there’s usually a lot of things going on at our house. I’d rather keep both eyes on the baby than juggle hot water at the same time…

Wabi Baby Electric Steam Sterilizer and Dryer Review

If you’re searching for a top-of-the-line baby bottle sterilizer, the very latest Wabi Electric Steam sterilizer could well be it.

Steam sterilizers are criticized because bottles are often left sopping wet and can’t be used immedialtey. Well, with the Wabi this does not happen.  It has an inbuilt drier and you can choose to dry for 30, 45 or 60 minutes depending how much of a rush you are in.

If you choose 45 minutes, the complete cycle will take 1 hour. The sterilizer can fit 8 standard size bottles. It can also sterilize all the baby essentials like nipples, teethers, breast pump parts, plates, bowls, and cutlery.

What I really like about this sterilizer is the “One button descaling” feature. This removes a lot of hassle associated with steam sterilizers. Usually, you have to mix a vinegar and water solution every 4 weeks to do this. Many sterilizers have been returned due to brown spots appearing on the heating plate, so it’s reassuring to know the Wabi sterilizer addresses this common problem.

If you’ve got the money (or a dear friend wants to buy you a really, really nice gift) the Wabi Sterilizer and Drier is a great investment.


  • Has A dryer – Makes things quicker, more sterile and convenient.
  • Easy to use – Just add water and press a button.
  • Large Capacity – Fits up to 8 baby bottles of any brand.
  • Countdown Timer – Many steam sterilizers don’t have this feature.
  • Automatic Storage – Automatically dries the bottles every hour for 10 minutes.
  • Automatic Descaler – No need to manually descale the sterilizer.
  • Sterilizes Everything – Teethers, Breast Pump accessories, and dinnerware.


  • The Price

This model is almost 3 times more expensive than other top rated steam sterilizers (without dryers admittedly).

Tommee Tippee Electric Steam Sterilizer Review

The Tommee Tippee steam sterilizer is a really innovative design that promises to remove 99.9% of all germs in 5 minutes flat. A great feature of this sterilizer is it has a top tray for all the small things that you need to go in like plastic nipples, teethers and pump parts.

The sterilizer takes 6 bottles of any brand. If they are a bit tall you can just remove the top tray so everything will fit. You can also use it plates, bowls, spoons, forks, etc, etc. So you can continue to use it when your little one becomes a toddler.

Also, the lid is reversible so you have a sterile prep area, too. If space is at a premium in your kitchen, this is a big plus. Tippee also include some free gifts. You get a sample 5oz bottle, a formula dispenser and nipple tongs.

AVENT 3-in-1 Electric Steam Sterilizer Review

The Avent 3 in 1 is a compact yet versatile Steam Sterilizer that many parents love. It’s called “3 in 1” because it has an adjustable size. The smallest size can be used for nipples, pacifiers, and teethers. The second for breast pump parts and toddler plates, bowls, etc, etc. The largest size is for the baby bottles.

The sterilizer is very easy to operate. Just push add water, push a single button and wait for the 6-minute cycle to finish. It’s very easy to clean, too. There’s only 3 pieces to wash – the cover, the big compartment, and the small compartment. The unit itself can be easily wiped down with a hot, damp cloth.

Milton Cold Water Sterilizer Review

A lot of parents prefer cold water sterilizers like Milton’s instead of expensive steam sterilizers.

One of the main reasons is that they find the process a whole lot easier. Just immerse the bottles and baby paraphernalia under the solution and wait around 15 minutes and that’s it. No microwave, no steam and no descaling to deal with.

Another reason is once the lid is opened, steam sterilizers lose their sterile environment. With the Milton Sterilizer, you can open and close the lid as many times as you want.

The submerged bottles will be good for up to 24 hours. This really suits us Moms as you the process only needs doing once-a-day. And the bottles and nipples will keep sterile for when we really need it.

  • Easy – No complicated instructions, simply immerse the bottles.
  • Any Brand – Any bottle is o.k as long as they ft!
