If you have a newborn, you already know that you will need to take extra care to keep your baby safe, especially during their first months after birth. That includes ensuring that anything that goes into their mouth is thoroughly cleaned with hot water and soap. You also want to sterilize their bottles and feeding accessories because cleaning alone will not eliminate harmful germs that are notorious for various infections. This is of utmost importance since your baby’s immune system is still undeveloped at this time, making them vulnerable to bacteria, viruses, fungi, and parasites. Even more susceptible are preemies and babies who are suffering from an illness.

The old-age practice for sterilizing baby bottles has been to boil, but this method is not very effective for some heat-resistant bacteria. It is also tedious and time-consuming because you will also need to dry the items. A baby bottle sterilizer uses heated steam to eliminate 99.9 percent of germs and bacteria effectively and is faster, and some can dry as well. Investing in sterilizer makes life a lot easier so you can concentrate on your baby more.

In this review, we will be discussing the different types of sterilizers in the market, how to use them, and we are confident that after reading through, you can identify one that suits your needs.

Do I Need to Sterilize My Bottles?

Washing the bottles with warm soapy water is excellent for cleaning, but it is not enough to get rid of all the germs. Sterilizing is an important step you need to take, especially if you have a preemie, a newborn below three months or your child is recovering from an illness to make sure all the items are germs-free. Even if your child does not fall in those categories, sterilizing is still a plus.

Different Ways to Sterilize a Bottle

  1. Using Electric steam

These sterilizers sit on your countertop and need to be plugged in. They work by using high-temperature steam to kill all the bacteria and germs. This is the best option if you need to sterilize your bottles frequently.

  1. Microwave steam

Microwave steam sterilizers also use steam to sterilize, but you put your bottles inside the microwave. 

They are a cheaper alternative to electric sterilizers and faster.

  1. UV light

Ultraviolet light is commonly used in the medical field to kill bacteria and germs. Now, bottle sterilizers are using this technology, and it is highly effective and fast. The unit has a bulb that radiates ultraviolet light to kill 99.9 percent of bacteria and dry your bottles. They come in various models and sizes. You can use the larger models at home or smaller portable models for while traveling.

  1. Cold-water sterilizing solution

This method requires you to wash the bottles or other feeding items with warm soapy water and rinse. Then, immerse clean items in the sterilizing solution, which is dissolved in cold water for the recommended duration. You can get the sterilizer either in solution form or tablet form. Of course, you will need to change the sterilizing solution every 24 hours or according to the manufacturer’s instruction.

Choosing the Best Baby Bottle Sterilizer (what to look for)

Ease of use

Baby bottle sterilizers should be simple to use. Choose a brand that is straightforward to operate.


If you use a lot of bottles, probably because you formula feed or you have multiples, you would be better off with a unit that can handle many bottles. If you are a breastfeeding mother who uses bottles only occasionally, a smaller unit may be suitable for you.

Drying capability

If you want a unit that lessens your workload, choose a sterilizer that can also dry your bottles. Microwave sterilizers are very fast in operations, but they leave the bottles wet, requiring you to dry hence adding to your workload.

Kitchen space

If you prefer an option that won’t occupy much space on your kitchen counter, go for a microwave option. You can keep these sterilizers in your cabinet and remove them on a need basis. Plus, they don’t require an outlet to work. On the other hand, electric sterilizers are large and require to be plugged in.


If your budget is already stretched thin with all the stuff you need to buy with a newborn, you can opt for microwave sterilizers cheaper than other sterilizers.


This may not be a deal breaker for most people, but it is a nice option to have. Sometimes you will want to go out with your baby visiting friends, family, outing, etc. A portable model will ensure your baby’s stuff are sterile at such times. You can get a compact UV sterilizer that uses batteries, which can be used anywhere, anytime.

Baby bottle sterilizer vs boiling

Boiling is a common method used by many parents to make their baby bottles safe for their babies to use. While it is a great method to kill many household germs and bacteria, it is not enough to eliminate some heat-resistant bacteria and their spores. On the other hand, sterilization is very effective in getting rid of all these harmful microbes and their spores.

The second reason why you should choose sterilizing over boiling poses a much higher risk of getting burned accidentally. Imagine having a pot of boiling water every day, several times a day, for ten minutes with your toddler running around the kitchen-not a very safe feeling. Sterilizers are well covered and do not pose the risks of open fires and spluttering boiling water.

Thirdly, sterilizing is faster than boiling. The time it takes for the water to begin boiling is longer than the time some sterilizers take to finish sterilizing (microwave sterilizers, for example). If you have a newborn, you will appreciate that sterilizers can save you so much time since some even can dry your items, affording you more time to rest or attend to your baby.

The final reason is that boiling wears your items much harder than sterilizers. If you choose to boil, it will not be long before the nipples and bottles start to crack. Sterilizers will not damage your items if you adhere to manufacture instructions.

Baby bottle sterilizer or dishwasher?

A dishwasher is excellent in getting your dirty dishes and bottles sparkling, but it does not eliminate the germs that could make your baby sick unless your dishwasher is optimized for sterilizing.

Most dishwashers use water temperature of between 54 to 76 degrees Celsius to kill most germs the water has to get to at least 100 degrees Celsius. Sterilizers use steam at high temperatures to kill germs and bacteria.

The other disadvantage of using a dishwasher is that even if it can sterilize, you have to transfer the items to a sterile container to keep them sterile. With a bottle sterilizer, you can leave the items tightly sealed and they will remain sterile for 12 to 24 hours.


How do I clean baby bottle sterilizer?

Your sterilizer will come with a manual detailing the care instructions, but generally, most require just simple hand washing or dishwashing with mild soap and water for the removable parts. For the rest of the unit, you can wipe with a wet kitchen towel.

If you are not using distilled water, limescale (white chalky deposits) will start accumulating on your sterilizer unit’s heating pad. You need to remove these frequently to prolong your unit’s user life, and it’s really simple to do. Just fill the pad with a white vinegar and water solution for 30 minutes or more (even overnight), rinse with cold water followed by an empty cycle to dislodge any remaining particles. You can also use lemon water or buy descaling sachets, which are also effective.

How do I use a baby bottle Sterilizer?

It depends on the type of sterilizer you have. You begin by cleaning all your bottles and parts with warm soapy water. Then load the clean bottles in the sterilizer and add the recommended amount of water to the unit.

If you are using a microwave sterilizer, place the unit inside the microwave for the recommended time. After it finishes the cycle, let the steam disperse before removing it from the microwave to prevent getting burned. Leave the bottles to cool before using them. Use a clean cloth to dry the bottles if you need to use them immediately. You can also keep the lid closed to keep the bottles sterilized for use later.

If using an electric sterilizer, you will need to fill with water to the recommended level and plug it in. When arranging your bottles and nipples, ensure that the mouth faces downwards so that the steam can hit every spot efficiently. 

When can you stop sterilizing bottles?

There is no harm in sterilizing for as long as your baby is using bottles, but it may not really make much of a difference once your baby can crawl around and is putting stuff in their mouth. Chances are that they will pick more germs that would be present in their bottles. That said, always ensure you thoroughly clean all their feeding accessories, teethers, and toys with hot water and mild soap. Also, sterilize whenever your child is recovering from an illness, so you don’t get the same microorganisms the immune system is working hard to fight are reintroduced.
