Best Baby Bottles Sterilizer for 2024

Best Baby Bottles Sterilizer

Our health depends on what we eat – and an infant’s health depends on what they are fed. Since they cannot chew yet, they rely on their mothers’ breastmilk or infant formulas. Bottles have a prominent place in the life of any baby who is not exclusively breastfed, and parents need to be sure that bottles and other feeding items for their babies are free of bacteria and other harmful organisms.

Top 4 Best Baby Bottles Sterilizer – Comparison

Why Is It Important To Sterilize Baby Bottles?

Sterilizing bottles, breast pumps, pacifiers, and baby items is important because of the under-developed immune systems of infants. This makes them susceptible to infections and illnesses caused by bacteria and viruses. It is the process of eliminating the presence of harmful microorganisms, which in the end provides more protection against germs, keeping your infant items free from contamination.

Health services around the world recommend that sterilization of infant feeding items should be done until the baby is at least 12 months old, because sterilization can help prevent infections such as diarrhea and vomiting.

Cleaning And Sterilizing Baby Bottles: The How-To’s

Making sure your baby’s bottles and other feeding equipment are germ-free isn’t just about washing them. You have to sterilize the bottle for added protection. Here’s a quick run-down of the top reminders for the three stages of preparing a spotless bottle for your infants:

1. Washing

Before you can sterilize your bottle, you have to wash them, either by hand or using the dishwasher.

If you are washing bottles by hand:

  • Wash your hands with soap and water first so that you don’t transfer any germs to the bottles.
  • Rinse the bottle under running water first. Try not to set them in the sink, as there may be germs present there that stick to the bottle.
  • Wash the bottle in hot, soapy water, using a clean bottle brush. It’s ideal to have a basin specifically for this purpose, that doesn’t get used for any other household washing.
  • After scrubbing, let the bottles air dry on a clean dish towel away from dust and dirt.
  • The washbasin and bottle brush should be washed clean every couple of days, either by hand or in the dishwasher.

If you are using a dishwasher to wash your bottles, then you can put them in on a hot water cycle. If your dishwasher has a heated drying cycle, that will help kill more germs. Remember to wash your hands before removing the bottles from the dishwasher.

After you’re done cleaning your bottles, you’re ready to sterilize.

2. Sterilizing


Boiling is the oldest form of sterilizing. It doesn’t take a big investment in equipment but is quite a process. In general, the parts of bottles are put in a large pot of water and boiled for 5-10 minutes. The downside is that not all bottles are suitable for this method as it also tends to damage teats faster, so you need to check your equipment regularly.

Chemical sterilization

Antibacterial solutions can be used to sterilize your infant items in cold water. These often come in liquid or tablet form and should be used according to the manufacturer’s instructions, both in terms of how to make the solution and how long your bottles must be submerged.

This method is not so good for metal parts as they may be damaged by repeated exposure to chemicals. You also need to make a fresh solution everyday.

Steam sterilization

The steam kills bacteria and other harmful microorganisms. Because of their effectiveness and ease of use, electric sterilizers are very popular among parents. They have to make sure that each bottle and teat is placed properly in the sterilizer, and then set it to go. Electric sterilizers usually turn off automatically or have a light that will indicate when the work is done.

Microwave sterilizers work in a similar way, except they are put in the microwave. Parents must follow the manufacturer’s instructions and use the right power setting, to make sure the bottles don’t melt. This system isn’t suitable for metal components.

3. Storing

The next step is to store your sterilized bottles and teats. Some sterilizers allow you to leave the bottles and teats inside the machine until you need them, ensuring they are completely sanitized. If you do want to remove them, wash and dry your hands before you touch the bottles, or use fresh tongs to handle them. Place the infant items in a clean container and put them in the fridge to keep them germ-free.

Which Baby Bottle Sterilizers Are The Best?

We can all agree that a baby bottle sterilizer eases our lives as parents and caregivers. However, with many baby bottle sterilizers available on the market, all with different features and specifications, shopping for one isn’t straightforward.

This Tommee Tippee sterilizer is made of plastic, and may produce a powerful smell during use. And since its material is plastic, the insides should also be washed frequently in order to maintain its quality.

Philips Avent Microwave Steam Sterilizer

Not a fan of electric bottle sterilizers? Then microwave steam sterilizers are for you. Our top pick for this type of bottle sterilizer would be the Philips Avent Microwave Steam Sterilizer. The manufacturer claims it kills 99.99% of microorganisms in a matter of minutes. Its cycle time runs between 2 and 6 minutes depending on your microwave. Even though it’s lightweight, it can fit up to four bottles and accessories and can keep them disinfected for 24 hours if you don’t open the lid.


Its lightweight size makes it very portable. You can use it at home, or even when you’re away. It’s also made with BPA-free plastic, so you can be sure it’s safe. It takes very little space compared to other bottle sterilizers and is dishwasher-safe. If you’re not using it, you can just store it in the cupboard or in the microwave.


Despite being portable, the Avent microwave sterilizer is too big for compact microwaves. Also, removing the bottle sterilizer from the microwave can be tricky, since its handle can be quite hard to grasp. If you’re in a full-bottle-feeding household, the capacity of four bottles might not be enough. Lastly, this machine produces a lot of steam, so be careful with opening the lid.
