  • Dish washing liquid

  • Water

  • Plastic comb

  • Plate or bowl

  • Hydrogen peroxide (3 percent strength)


Wash the brush soon after every use. That way, nothing will have time to dry on the bristles and it will be easier to keep clean. If you’ve sanitized baby bottles in boiling water on the stove, you can also put the bottle brush in the hot water to help clean it (after you’ve removed the baby bottles).


Unlike many sponges, which can be cleaned and sanitized in a microwave, bottle brushes usually have metal components (which would create sparks) and plastic bristles (which could melt).

Bottle brushes are used for cleaning many things, but are most well-known for cleaning baby bottles. Most bottle brushes, no matter what they are intended to clean, consist of a flexible metal stem, with one end covered in plastic bristles. Many brushes are tapered so they can be easily inserted into a bottle opening. Cleaning bottle brushes is essential if you wish to re-use them. If these brushes aren't cleaned properly, you risk contaminating the very items you are trying to clean with the brushes.

Step 2

Let the brush soak in the hot soapy water for at least 15 minutes. This will loosen debris stuck to the brush.

Step 3

Use a clean plastic comb to gently comb through the brush. This will remove trapped food or dirt particles from the bristles.


Step 4

Rinse the brush under warm or hot water. Place the brush in a clean bowl or on a clean plate. Pour hydrogen peroxide over it, making sure the peroxide gets on all the bristles.

Step 5

Let the peroxide remain on the brush for at least 15 minutes to help sanitize it. Rinse off the brush under running water and let it air dry.
