How to Clean Baby Bottles?

Cleaning baby bottles can prevent diseases

One of the most basic aspects of baby care is cleaning baby bottles. As a new parent with little to no experience on taking care of babies, you may find the subject of how to clean baby bottles an unfamiliar territory.

Improper cleaning and sterilization of baby bottles can lead to certain problems such as; gastroenteritis and food-borne diseases. So, I’ve decided to lend a hand out to expecting or new parents with this easy tutorial, in order to prevent harmful problems like these.


First thing’s first; let’s lay out the materials that we need:


  • Used baby bottles
  • Mild dish soap
  • Baby bottle brush
  • Nipple brush
  • Sterilizer (optional)
  • Tongs
  • Metal bowl
  • Metal pot with cover
  • Sponge

How to Clean Baby Bottles Properly

Step 1: Prepare your utensils and workplace

Before starting to clean your baby bottles, sanitize the area you’ll be working in first and foremost. If you’ll be washing in kitchen sink (most likely), clear out anything unrelated. If there’s still dirty dishes in the sink, do them first before washing your bottles. Furthermore, give your countertop a good wipe down to get rid of any dirt and debris.

All of your utensils, including your brushes and tongs, need to be as clean as possible. To prepare your utensils for cleaning, soak them in a mixture of hot water and mild dish soap. Make sure you wash your hands thoroughly beforehand, too!

Ensuring that your work area and utensils are sanitized, just like with a diaper pail, can reduce the spread of bacteria on your baby’s stuff.

Step 2: Disassemble and soak

Before you wash your baby bottles, you must first disassemble it to separate the bottle, cap, ring, and nipple from each other. Afterwards, soak the cap, ring, and nipple in a metal bowl filled with hot, soapy water.

Rinse out leftover milk in the bottles, too. If the milk has spoiled inside the bottle, wash it more thoroughly.

Step 3: Wash your baby bottles

Washing baby bottles can be tedious, especially if you are a busy parent, but it is always necessary for the well being of your baby. Make sure that in this step, you have enough time to clean all the nooks and crannies of your bottles. Do not rush!

To start, pour hot, soapy water inside your bottles. Then, wash each bottle by rotating the baby bottle brush inside. Remember not to use a regular kitchen sponge for this, as kitchen sponges contain a lot of bacteria which is unsafe for your baby’s sensitive stomach.

Step 4: Wash the caps, rings, and nipples

Wash the caps and rings of your baby bottles with a clean sponge (used only for bottles!). For the nipples, use the nipple brush to wash away every trace of milk inside the rubber.

Step 5: Rinse all the parts

After thoroughly washing your baby bottles and its parts, rinse them with running water in order to remove the soap. Make sure to do this as thoroughly as you can to prevent soap from remaining in the bottle.

Always make sure to use clean water for this step.

Step 6: Use a sterilizer

To fully rid your baby bottles of bacteria, you can opt to use a sterilizer. However, a sterilizer isn’t as nearly necessary as a baby thermometer. If you don’t have or don’t want to use a sterilizer, you can choose an alternative step:

In a clean metal pot, place all your baby bottles upright. Also throw in the caps, rings, and nipples. Then, boil water in a kettle and pour the boiling water inside the bottles and onto the other parts until you have almost filled the vessel.

Step 7: Dry your baby bottles

The last step is drying your baby bottles and setting them aside for future use. After the boiling water in the pot has cooled down (or after you’ve sterilized your bottles in a sterilizer), you need to transfer them on a drying rack.

To do this, use your sterilized tongs (not your hands!) to transfer the bottles to a clean drying rack. Make sure this drying rack is not next to dirty dishes, food, or other things that can contaminate your bottles.

When the bottles have fully dried, you can then put them back together again and store them in the bottle basket.
