How to Sterilise Baby Bottles Using Stove or Microwave

Steam sterilisers aren’t the only way to keep your baby’s bottles safely hygienic. If you don’t own one, or are going to be away from home without space to pack another bulky bit of baby paraphernalia, use these simple methods to do the job just as well:

Baby bottle

Before you start, always wash the bottles and teats in hot, soapy water and a bottle brush to clear out hidden residue. Try to do this as soon as possible after a feed so the milk doesn’t harden and prove difficult to remove.

Also ensure that there’s no cracks in bottles or teats – bacteria lurks in these crevices, so it’s safest to toss damaged bottles.

Sterilising by boiling in water

Place bottles and teats in large pan and cover completely with water. Bring to the boil and let simmer for 10 minutes; make sure everything stays submerged during this time.

NOTE: teats will wear out more quickly using this method.


Check manufacturer’s label to ensure bottles are microwave safe. Then simply put in microwave for 90 seconds without the teats or lids on.

Keep sterilising bottles until baby is at least one year old – or until you stop using bottles altogether.
