Benefits of A Baby Bottle Sterilizer

Bottle feeding can be a hassle, especially when it comes to keeping the bottles and nipples clean. This is where a bottle sterilizer comes into play—these provide a quick and easy way to eliminate germs and bacteria.

Bottle sterilizers are beneficial for:

Easy Cleaning

As a mother, it’s challenging to find time to clean your baby’s bottles properly. But, by using a bottle sterilizer, all you have to do is rinse the bottle and nipple, then place it in the sterilizer.

Depending on the model, you might have to add water or place it in the microwave—it beats having to boil the bottle over the stove, though.

Boiling the bottle is reliable as well; however, it can take time that you’d rather spend with your little one. It’s also less energy efficient, so it costs more.


Bottle sterilizers can remove up to 99.9 percent of germs and bacteria present on the bottle and nipple. Some use high-temperature steam that blasts the germs away, leaving a clean bottle, safe for your little one. Others use UV light to kill bacteria and germs.

It’s especially important for newborn babies as they haven’t yet developed their immune system—making them vulnerable to diseases.


Many bottle sterilizers are available on the market, most of which can clean more than one bottle at a time. These are exceptionally efficient if you have a demanding baby or multiples. One of the largest bottle sterilizers can hold up to 11 bottles at a time.

Types of Baby Bottle Sterilizers—Attributes That Differentiate Sterilizer Types

There’s a range of bottle sterilizers on the market, so it’s relatively easy to find one you like. Where the types differ is in the way they sterilize—here are the common types:


Electric bottle sterilizers are probably one of the most common types. It’s plugged into an outlet, and all you have to do is fill the water reservoir or tray. The power will boil the water to create steam.

What most parents enjoy with electrical sterilizers is that you get to control the duration of the sterilization. Plus, many models include several handy features, such as additional small compartments for bottle nipples.

Some even include cooling and drying features and safe storage, so you can always have clean bottles ready.

UV-Light Sterilizers

This type of sterilizer uses UV light that kills germs and bacteria. It uses the same technology as you can see in UV water purifiers.

The UV light goes through the bottles and works by altering the chromosomes of the germs, which prevents cell division.

One of the significant advantages of UV bottle sterilizers is that they eliminate the need for water and hot steam. The bottles will be ready to use without the need first to dry them off.

UV sterilizers look similar to a mini-fridge or a tiny dishwasher. You simply place your bottle inside the device and turn it on.

Microwave Sterilizer

A microwave bottle sterilizer is an affordable alternative to electrical models. It comprises a box fitted with slots to accommodate several bottles. You just add water, place it in the microwave and turn it on.

The box will create steam to sterilize the bottles and nipples. How long it needs in the microwave varies between models—always read the manual before use.

A major plus of microwave bottle sterilizers is that they’re more compact and take up less counter space. It’s an ideal choice for compact kitchens where a large UV model or electrical sterilizers wouldn’t fit.

What To Look For When Choosing the Best Bottle Sterilizers?

It’s essential to choose the right bottle sterilizer for your baby. The size has to suit the space available, and it has to meet your needs—whether it’s a simple device or one with added features. We’ve come up with a quick guide to help you find the best bottle sterilizer for you.

1. Bottle Capacity

Depending on your feeding style, bottle capacity will play a significant role in how suitable the device will be for you.

Mothers who bottle-feed only will need a larger capacity since you’ll require clean bottles ready. A newborn will need to feed nearlyevery two hours, day and night—therefore, it’s challenging to have sterile bottles ready.

Finding a sterilizer that lets you clean multiple bottles at a time will help to ease feeding time. A handy feature, such as contained storage, will enable you to sterilize bottles in advance and store them safely within the sterilizer—this is handy as you’re getting ready for the night feeds.

If you’re breastfeeding and bottle feeding, however, you won’t need as many bottles. You can, therefore, choose a smaller capacity that takes maybe two to three bottles at a time.

2. User-Friendliness

Having to get the manual out every time you need to sterilize your bottles is a hassle. A sterilizer should be straightforward to operate with only a few buttons to use.

3. Required Counter Space

Depending on the size of your kitchen, the size of the sterilizer is important. Some moms prefer the compactness of microwave sterilizers for this reason—they’re easy to store in a cabinet or inside the microwave itself. When needed, you can quickly whip it out and sterilize your bottles.

If you opt for an electrical sterilizer, consider storage and counter space required, and the location of power outlets. The same goes for UV light sterilizers that also take up significant space and will require a close power outlet.

4. Safe Materials

The bottles and the sterilizer itself are subjected to high temperatures. It’s, therefore, crucial that the sterilizer is made of safe materials. Cheaper models might be budget-friendly; however, they’re not always safe.

Choosing a BPA-free bottle sterilizer is ideal, both in quality and for peace of mind.

Precautions for Using a Baby Bottle Sterilizer

Merely putting your baby bottles in the sterilizer will not be enough—here are a few precautionary safety tips to keep in mind:

  • Clean prior to sterilization: Before sterilizing your bottles, wash them in hot, soapy water to get rid of any leftover formula or milk. It’s best to do this as soon as the bottle is empty—this will eliminate any chances of milk getting stuck in hard-to-reach areas.
  • Disinfect: Before sterilizing baby’s bottles, disinfect your hands and the area you’re working in (counter or table). You should also use clean towels or cloths to dry off the bottles to avoid contamination.
  • Use high-quality bottles and nipples: The bottles and nipples should be BPA-free. Bisphenol A is commonly used in water bottles and food storage containers. However, issues can arise when you heat the plastic—high heat can cause BPA to leach from the bottle.Exposure to BPA can affect the brain of fetuses and young children.
  • If you’re using glass bottles: Keep an eye out for any cracks in the glass. If cracks are detected, disposed of the bottle to avoid any accidents.
  • Keep a safe distance: If you’re using an electrical or microwave sterilizer, keep in mind that it will be hot. There is scalding water within the device, so avoid sterilizing bottles while holding your baby and keep other children at a safe distance.

Best Way to Use a Bottle Sterilizer

How you should use a bottle sterilizer depends on the unit you have. But, it’s always vital to clean your bottles and nipples thoroughly prior to sterilizing them.

If your sterilizer doesn’t have a cooling function, make sure you allow the bottles to cool fully before giving it to your baby.

You should treat your newly sterilized bottles with care. Wash and disinfect your hands thoroughly before handling them.

Is Bottle Sterilization Necessary? Addressing the Controversy

Not all parents agree when it comes to bottle sterilization. Some mommies do it often (daily or weekly), while others only sterilize their bottles once in a while.

Experts recommend that you sterilize your baby’s bottles every few weeks to ensure they’re germ-free.

Although you don’t have to sterilize your baby’s bottles after every use, if that’s what you choose to do, it’s totally fine. Babies have under-developed immune systems, making them vulnerable to bacteria and germs—so keeping their feeding bottles clean is essential.

If your baby bottles and nipples are dishwasher-safe, wash them on a hot, sanitizing cycle with a heated dry cycle. This will also sanitize the bottles thoroughly—and it’s less work for you.
