Baby bottles make it convenient for you, a loved one or a babysitter to feed your baby expressed breast milk or formula. However, it’s essential to keep bottles clean so they don’t introduce bacteria into your baby’s system, explains KidsHealth. A proper cleansing and sanitizing system can also help remove lingering odors formed by milk left inside the bottles that might make you nauseated or change your baby’s willingness to take future meals from the container.
Pour out any leftover milk that might be causing the baby bottle. Rinse the bottle and nipple with water.
Scrape any milk residue from the sides of the bottle with a bottle brush. Use the brush to scrub the inside of the bottle and nipple, which may also have a milk odor, suggests the California Pacific Medical Center.
Wash the bottle with dish washing soap and hot water. You can wash plastic or glass baby bottles in the top rack of the dishwasher for a thorough cleaning, notes KidsHealth. In addition to removing milk odor, a proper cleaning can prevent the formation of bacteria inside the containers.
Deodorize the bottle if it has lingering odors from the milk. Pour 1 tsp. baking soda into the bottle and fill it with warm or hot water. Shake the container to help the baking soda solution cleanse the inside of the bottle before rinsing it out.
Remove stubborn milk odors from bottles by soaking the containers overnight. You can create a deodorizing liquid in a large plastic tub, metal baking pan or glass casserole dish or bowl. Add 4 tbsp. baking soda and 1 quart of hot or warm water. Let the bottles and nipples soak in the solution, and then wash the containers completely with dish washing soap and hot water. Allow them to air dry completely before using them.
