The Essential Guide to Cleaning and Sanitising Baby Bottles

by Dr. Brown's

Keeping baby feeding items clean is one of the most important everyday practices for protecting your baby’s health. Bottles, nipples, and pumping parts come into direct contact with breast milk or formula, both of which can encourage bacterial growth if not cleaned properly. While official health guidelines provide clear direction, parents also need routines that are practical and easy to follow at home.

This guide explains why cleaning and sanitising baby bottles matters, how to do it correctly, and when extra sanitisation may be beneficial.

Why Cleaning Baby Bottles Matters

Milk residue left in bottles or nipples creates an environment where germs can multiply quickly. In young babies, this can contribute to digestive discomfort or illness. Consistent and thorough cleaning helps reduce these risks and supports safe feeding, especially during the early months.

How Often Should Baby Bottles Be Cleaned?

Baby bottles and feeding parts should be cleaned after every feed.

  • If breast milk is left unfinished for more than two hours, it should be discarded.
  • Prepared formula that has not been used can be stored in the refrigerator and used within 24 hours, but once feeding has begun, leftovers should not be reused.

Simply rinsing a bottle is not enough. Establishing a regular cleaning routine, such as washing bottles after the final feed of the day, can help ensure nothing is missed.

Cleaning Bottles in the Dishwasher

If your Dr. Brown’s bottles and accessories are dishwasher safe, this can be a convenient option.

  • Take everything apart: Separate bottles, nipples, rings, caps, and vent components from Dr. Brown’s Anti-Colic Options+ bottles.
  • Rinse first: Rinse parts under running water to remove visible milk residue.
  • Load carefully: Place items in a dishwasher basket or closed container to prevent smaller pieces from moving during the wash cycle.
  • Use heat: Select a hot water wash with a heated drying option if available.
  • Dry safely: Allow items to air-dry completely. Avoid using dish towels, which can transfer germs.

Always wash your hands before handling clean feeding items.

Cleaning Bottles by Hand

Hand washing is another effective option when done correctly.

  • Wash hands thoroughly before starting.
  • Disassemble all parts completely.
  • Rinse under running water, using a separate wash basin rather than the sink itself.
  • Wash with hot, soapy water: Use a clean bottle brush reserved only for baby items. Push water through nipple holes to clean thoroughly.
  • Rinse well and allow all items to air-dry on a clean towel or paper towel.

Clean the wash basin and bottle brush regularly to prevent bacteria build-up.

Cleaning Bottle Brushes and Wash Basins

The tools used to clean bottles also need regular attention. Brushes and basins can be washed with hot soapy water or cleaned in the dishwasher if suitable. Periodic sanitising, through boiling or steam, helps reduce germ transfer between washes.

Cleaning Formula Containers and Scoops

There is limited evidence that babies become unwell from contamination on the outside of formula containers. If preferred, the exterior of the container can be wiped with a disinfectant before opening. The inside should never be rinsed or cleaned.

Formula scoops should remain dry. If a scoop becomes soiled, wash it with soap and water and allow it to dry completely before placing it back in the container.

When and Why to Sanitise Baby Bottles

Sanitising adds an extra layer of protection beyond cleaning. While dishwashers with heated drying cycles may reduce the need for separate sanitising, it can be especially helpful when:

  • Babies are under two months old
  • Babies were born prematurely
  • Babies have weakened immune systems

How to Sanitise Feeding Items

There are several effective sanitising methods:

  • Boiling: Place disassembled parts in a pot of water, bring to a boil, and continue for five minutes.
  • Steam sterilising: Use microwave or electric steam systems according to manufacturer instructions. Dr. Brown’s Steriliser and Dryer offers a convenient solution by combining steam sterilisation and drying in one unit.

After sanitising, items should be air-dried fully before use.

How Often Is Sanitising Needed?

Daily sanitising is recommended for newborns and babies with higher health risks. For older, healthy babies, thorough cleaning after each use may be sufficient. Parents should choose a routine that suits their baby’s needs and seek advice from healthcare professionals if unsure.

Practical Tips for Everyday Bottle Care

  • Create a consistent cleaning routine
  • Use dedicated cleaning tools for baby items only
  • Store clean bottles in a dry, protected area
  • Regularly check nipples and bottles for signs of wear

Final Thoughts

Keeping feeding equipment clean does not need to be complicated, but it does require consistency. By following simple cleaning and sanitising steps, parents can feel confident that feeding times are safe and comfortable.

With the right care routine and reliable products such as Dr. Brown’s Anti-Colic Options+ bottles and Dr. Brown’s Steriliser and Dryer, maintaining hygiene becomes a manageable part of everyday baby care.
