  • Bottle brush

  • Vinegar

Thoroughly clean your baby's bottles to remove film buildup.

Whether you decide to breast-feed or bottle-feed your baby, you want him to consume liquid that is safe for him to ingest and not filled with bacteria or potentially harmful ingredients. It's common knowledge that when you first purchase bottles, rings and nipples that you should sterilize them in boiling water, but sterilizing isn't a necessity for every wash. Due to the buildup of milk fat or hard water, your bottles may form a film either inside or on the outside of the bottle. Even though the film isn't necessarily harmful, it's not exactly something you want to willingly feed to your infant.


Step 1

Fill a sink with hot, soapy water. Use an antibacterial soap. Do not use lukewarm or cool water. It's important to make the water as hot as you can stand it for the best cleaning power.

Step 2

Scrub the outside of the bottle with a sponge to remove any film. Fill the bottle about halfway full with the hot, soapy water, and use a bottle brush to cleanse the inside -- being sure to get the edges and under the lip where the nipple goes on.

Step 3

Rinse the bottle in a solution of half water and half vinegar. Vinegar is effective at breaking down minerals, especially calcium and magnesium, which are present in hard water and can build up on dishes, including bottles.

Step 4

Rinse the bottles off, and leave them to dry upside down.


You may have to replace the nipples more often than you replace the bottles themselves, since the silicone is likely to break down after so many washings.
