How to Use Bottle Warmer and Sterilizer

Should Bottles Be Dry before Putting in Sterilizer?

It is not necessary to dry bottles before putting them in the sterilizer. However, if the bottles are wet or damp, they should be dried before being put into the sterilizer. This will help ensure that no bacteria or other contaminants remain on the bottle’s surface after it has been sterilized. Additionally, some manufacturers recommend drying off any excess moisture before placing the bottles in the sterilizer to ensure the most effective cleaning. It is also important to note that some bottle warmers and sterilizers have built-in drying systems, so check with your manufacturer’s instructions to determine if your device has this feature.

Before using a bottle warmer or sterilizer, it is important to thoroughly clean the bottles first, either by hand washing or with a bottle brush. This will help remove any remaining bacteria and other contaminants before sterilization begins. Additionally, make sure to follow the instructions closely – some products require pre-heating or rinsing water prior to use in order to achieve maximum effectiveness. Finally, always read the manufacturer’s directions carefully to make sure you are using the product correctly and safely.

8 Methods How to Use Bottle Warmer and Sterilizer

1.  Read the Instructions

Before using your bottle warmer and sterilizer, be sure to read the instructions that came with the product. This will ensure that you are using the product correctly and safely. If you have any questions or concerns, contact the manufacturer for more information. Make sure that all of the parts are clean and in good working order before use.

Try to use the same type of water each time you use the product, as different types of water can affect how well it works.

2.  Choose the Right Size Bottle

Be sure to choose a bottle that is the correct size for your baby. If the bottle is too small, it may not fit properly in the warmer and sterilizer. If the bottle is too large, it may not be heated evenly. It is also important to make sure that the bottle fits snugly in the warmer and sterilizer so it doesn’t move around while being warmed or sterilized. If possible, buy bottles that are specifically designed for use with a bottle warmer and sterilizer.

3.  Fill the Bottle With Water

Fill the bottle with water before placing it in the warmer and sterilizer. This will help to evenly distribute the heat and prevent hot spots from forming. Ensure you use the right amount of water – too little and the bottle won’t heat up properly, while too much can cause it to overflow.

If you’re using a bottle warmer, make sure the water level is at least two centimeters below the top of the nozzle. Additionally, make sure the bottle is filled with the correct type of water. The best option is to use bottled or filtered water, as tap water can contain minerals that can cause the warming chamber to become clogged.

4.  Place the Bottle in the Warmer

Carefully place the filled bottle into the warmer. Make sure that the nipple is pointing up so that it does not come into contact with the heating element. Once the bottle is in place, choose the setting that corresponds to how long you would like to warm the bottle. Most models will provide warming options for 3, 5, and 10 minutes. Additionally, some models feature a defrost setting for warming frozen breast milk.

5.  Set the Timer

Set the timer on your warmer and sterilizer according to the instructions. Most products will have a specific time that they should be used for each size bottle. Make sure you pay attention to the instructions and set the timer correctly. This will ensure that the bottles are heated evenly and that they are completely sterilized.

If the timer is set too short, the bottles may not be heated fully. Too long, and they can become overheated and cause damage to the material. Try to find a timer that is adjustable so that you can adjust it to the size or type of bottle that you are using.

6.  Remove the Bottle Carefully

Once the timer goes off, carefully remove the bottle from the warmer and sterilizer. Be sure to use a towel or pot holder to protect your hands from burns. If the bottle is too hot to touch, allow it to cool down until you can safely handle it. However, do not leave the bottle in the warmer/sterilizer for too long, as it may cause milk to spoil or burn.

Carefully Remove the Bottle

7.  Check the Temperature of The Milk or Formula

Before feeding your baby, be sure to check the temperature of the milk or formula by shaking a few drops onto your wrist. It should feel warm, but not hot, to touch. If it is too hot, wait for a few minutes before feeding your baby. Reheat the bottle if necessary and check again before giving to your baby.

8.  Clean the Warmer and Sterilizer

After each use, be sure to clean your bottle warmer and sterilizer. Wipe down the interior with a damp cloth and check for any clogs or dirt buildup. If necessary, use a brush to remove any stuck-on residue. Once you are satisfied that it is clean, turn off the machine and allow it to cool down before storing it.

By following these steps, you can easily use your bottle warmer and sterilizer to keep your baby’s bottles safe and warm. Be sure to always read the instructions on your product carefully before use and never leave the machine unattended while operating. With proper care and maintenance, your bottle warmer and sterilizer should last for many years.

Things to Consider When Using Bottle Warmer and Sterilizer

1. Check the Age of Your Baby:

Bottle warmers and sterilizers can be used for newborns and older babies, but it is important to make sure that you are using the proper technique for your baby’s age and size. Newborns generally need slightly warmer temperatures than older babies when it comes to bottles and items that come in contact with them.

2. Read the Instructions:

Each bottle warmer or sterilizer is different, so it is important to read the instructions carefully before use. Make sure you understand how much water to pour in, what temperature settings are appropriate, and any other special instructions for the specific model.

3. Sanitize Regularly:

Using a bottle warmer or sterilizer regularly will help keep bottles clean and free of bacteria. However, it is important not to overdo it, as too much sanitizing can lead to an accumulation of chemicals that could harm your baby. Try not to use the same bottle and accessories for more than a week before sanitizing them, or replace them with fresh items as soon as possible.

4. Don’t Overfill:

When using a bottle warmer or sterilizer, make sure that you do not overfill it with bottles and accessories. This can cause water to spill out and can also affect the temperature needed for proper sanitation. It is best to follow the instructions for how much liquid should be used in each model so that everything comes out properly sanitized and safe for your baby.

 Do Not Overfill It With Bottles

5. Monitor Temperature:

When using a bottle warmer or sterilizer, always check the temperature of the water to make sure it is the correct temperature for your baby. If the water is too hot, it can scald your baby’s skin, so always use caution and check the temperature before use.

Following these simple steps will help ensure that you are using a bottle warmer or sterilizer correctly and safely for your baby. Keep in mind that no two models can be exactly alike, so always read the instructions carefully before each use to make sure everything is done properly.  With proper care and maintenance, you should have many years of safe and effective use from your bottle warmer and sterilizer!


If you are interested in using a bottle warmer and sterilizer, there are many ways to go about it. You can find them online or in stores that sell baby products. There are different models and brands available, so be sure to do your research before making a purchase. Be sure to follow the manufacturer’s instructions carefully when using the product.

Hi, my name is Loren. I live with my husband and 4 lovely kiddos in the Eastern part of San-fransisco. I have a smart beautiful,curious 6 year old daughter, a handsome 11-year-old son, an intelligent and tech geek 15 years old son and a creative, artistic 12-year-old stepson. With each of my kids being five years apart, I feel that I’m now continually phasing in and out of each stage of parenting! I’ve learned a lot about the way children learn and behave, especially in a school setting with regards to curriculum. I enjoy sharing that insight through my writing and hope that it can help others.
