How to clean and sterilize bottles

When you first get your bottles:

  • Wash the bottle, all the parts and – for the first use only – boil the nipple for five minutes.

Everyday cleaning:

  • Wash all parts in hot water and gentle detergent.
  • Use the included Cleaning Brush to clean the holes in the vent insert and the straw-like tube in the vent reservoir.
  • Wash the bottle and nipple using a non-scratch sponge or Bottle Brush.
  • Let everything fully dry before storing in a clean place.
  • Bottle, parts, and nipple are dishwasher (top rack) safe, but ensure you clean small areas in the internal vent system prior to putting in the dishwasher to avoid mold build-up.

  • The Centers for Disease Control states that, “Sanitizing is particularly important when your baby is younger than 3 months, was born prematurely, or has a weakened immune system.” In those cases, sterilizing at least one daily is recommended.
  • For older, healthy babies, it may not be necessary if the bottle and parts are carefully cleaned after each use. We recommend sterilizing in these situations:
    • Sterilize before the first use of the bottle after purchase
    • Sterilize after traveling with the bottle
    • Sterilize if milk or formula has been inside at room temperature beyond the recommended time period
    • Sterilize if it comes in contact with contaminated surfaces or floors
    • Sterilize daily when baby is sick with the flu or other viral or bacterial infections
