How to Use a Microwave Bottle Sterilizer

If you are looking for an easy way to sterilize your baby bottles and accessories, a microwave bottle sterilizer is a great option. These sterilizers use your microwave to create steam to sterilize your bottles. They are easy to use and you can have sterilized bottles in just a few minutes. They are lightweight and compact, so they are great for those trips to Grandma's house, too. Follow these steps to sterilize your bottles with your microwave bottle sterilizer.

Wash all parts of the bottle sterilizer with warm soapy water and rinse before each use.

Add water to the base of the microwave bottle sterilizer. The amount varies slightly depending on the brand, but most require about 200ml. Put the bottle rack in the base and then place the lid over the base and lock it into place.

Load the bottles, nipples and other parts into the sterilizer. Place it in the microwave.

Microwave on high for the correct amount of time based on the size of your microwave, usually from two to six minutes. Let it cool in the microwave for 2 minutes after it stops.

Remove the lid carefully. Make sure that it is pointed away from you to let the steam escape. The bottles and accessories be removed now, but they may still be hot so remove them with care. Empty any left over water from the base.


Be sure to add the correct amount of water. Adding too little can damage the sterilizer.


Do not use bleach or other chemical solutions.

Do not overload the microwave bottle sterilizer.
