How to Sterilize Breast Pump Parts


Sterilizing a breast pump daily is important to help prevent both mother and baby from becoming ill. Sterilization is a simple, affordable process that kills the bacteria that can grow in the breast pump. During sterilization, bacteria are eliminated at a temperature around 200 degrees F. Because water boils at 212 degrees F, boiling breast pump parts is a quick way to sterilize them.

Things You'll Need

  • Breast pump
  • Large pot
  • 1 gallon water
  • Dish-washing soap
  • Clean kitchen tongs
  • On a stove top, bring the water to a rolling boil in the pot.

  • Disassemble the pump.

  • Wash each non-electrical piece of the pump with warm water and liquid dish-washing (preferably antibacterial) soap.

  • Rinse each piece with hot water for 10 to 15 seconds.

  • Using clean kitchen tongs, gently place each part into the pot of boiling water.

  • Leave the parts in the boiling water for at least five minutes and up to 10 minutes.

  • Carefully remove each part with clean tongs.

  • Allow the parts to air dry. Do not towel dry--this can spread bacteria from the towel to the pump.

  • Once dry, put the pump back together, avoiding the areas that will come in direct contact with the breast or milk.

Tips & Warnings

  • Do not submerge batteries and electrical parts of the pump in water. Wipe these parts after use.
