What Is A Baby Bottle Sterilizer?
A baby bottle sterilizer is a device that kills germs within and on the baby’s feeding bottle. The sterilizer resembles a plastic box or container that has slots to place the feeding bottles, along with a tray to hold the other components. Most sterilizers use steam to remove harmful bacteria, almost entirely. A clean and sterile baby bottle reduces the risk of the baby developing gastrointestinal problems to nearly zero.

Do You Need A Sterilizer?
It is important to sterilize the baby’s feeding bottles after you have cleaned them with soap and clean water. Warm water and disinfectant soap may remove the food residue but are not enough to kill pathogens in the bottle. Sterilization removes pathogens, adding that extra layer of protection.
While all baby bottle sterilizers aim to make the bottle sterile, the techniques or methodologies used by each are different.

What Are The Different Types Of Baby Bottle Sterilizers?
There are three types of baby bottle sterilizers:
- Electric sterilizers are plugged to a standard wall power outlet. They use electricity to make steam from the water in the tray. These sterilizers let you control the duration of sterilization and may even have a cooling or drying feature. Other benefits may include auto shut off and special trays to place other items like bottle nipples.
- A microwave baby bottle sterilizer is a box with slots to place the bottles. It creates steam when placed in a microwave: pour water, place the box in the microwave oven, and turn the oven on. The recommended time of sterilization varies as per the manufacturer and the wattage of the microwave oven. Microwave sterilizers are cheaper and also consume less space.
- Sterilization bags are zip-locked bags in which you pour water and put the bottle. The bag is then placed in the microwave oven and turned on for the time recommended by the manufacturer. The water evaporates into steam and sterilizes the bottles. It works the same way as a standard microwave sterilization box. While sterilization bags have limited capacity, they are portable and reusable for a limited number of times.
- UV light-based: These electric sterilizers use UV light to sterilize the bottles. The UV sterilization technology is similar to what we see in UV water purifiers except that here the UV light passes through the bottles. These sterilizers do not use steam or leave the bottles damp after sterilization. There are few models of UV sterilizers, which also makes them more expensive compared to electric and microwave devices.

How To Choose A Bottle Sterilizer?
The type of sterilizer you need depends on how you intend to use it. Look for the following features in the baby bottle sterilizer, to make the right choice.
- Easy to use: Operating and cleaning the sterilizer should be easy. Ease-of-use and control can let you sterilize the bottles safely and correctly.
- High quality and baby friendly plastic: The plastic of a bottle sterilizer is subjected to a lot of heat. Therefore, it needs to be durable and withstand several cycles of bottle sterilization, without releasing toxins. So, make sure the sterilization box or cover is free of harmful compounds like BPA, which can find their way to the bottle.
- Tray for bottle accessories: You will also need to sterilize the bottle nipples and other baby items like the pacifiers. Having a bottle sterilizer with a tray can let you sterilize all items at once, thus saving you time.
How To Clean A Baby Bottle Sterilizer?
Cleaning the sterilizer involves simple steps and the use of some additional cleaning agents. Refer the user manual for the manufacturer’s instructions on cleaning. In general, cleaning of bottle sterilizers involves the use of:
- Dishwasher or warm soapy water: If you are using a microwave sterilizer, then you can place all the parts in the dishwasher. In the case of electric and UV sterilizer, remove the washable components and put them in a dishwasher. Wash the usual way.
Wash the sterilizer separately without any other utensils to prevent any contamination. Alternatively, you can also use a brush, sponge, and warm soapy water to gently clean the components.
- Descaling: Hard water can leave mineral scales on the heating plate, and excessive scales may impair functionality. Therefore, it is essential to descale the unit. Remove the heating plate, throw away any water, and wipe it clean with a dry cloth.
Use a descaling solution made for sterilizers or regular white vinegar. Pour some vinegar on the heating pad and leave it for 30 minutes or up to 24 hours if you have a lot of scales. Discard the vinegar and rinse the heating plate with water. Wipe away the water with a clean, dry cloth.
Note that descaling is only required in electric sterilizers because they have a metal heating pad that develops scales easily.
Never assemble components of the electric or UV sterilizer while they are wet or damp since water may spoil the electrical components. Once the sterilizer is clean, run it empty or with standard bottles once to rinse any remnants of soapy water and vinegar.

Tips For Baby Bottle Sterilizer Usage
Here are some best practices for optimum usage and maintenance of the sterilizer:
- Only place washed bottles: Wash the bottles with soap and water before putting them in the sterilizer. Never directly place dirty bottles with milk in them. A sterilizer is meant to sterilize bottles that have already been cleaned with water and soap.
- Descaling once in four weeks: It is good practice to descale your electric sterilizer unit once in four weeks or about once a month. It prevents the formation of excess scales that can be hard to clean later. You may check the manufacturer’s guide to know how frequently you should descale.
- You can also use distilled water: If you live in an area that contains very hard water, then you can use distilled water instead of regular filtered water for sterilization.
Sterilizing the baby’s bottle is essential and should be a part of your daily routine of preparing the bottle for feeding. Sterilization can protect your baby from several infections. Maintenance of the sterilizer is vital as well to keep it in good condition for as long you need it.
