How to Clean an Avent Steam Sterilizer

Updated July 19, 2017

A sterilizer is a helpful item to have when feeding your baby. If you don't use an automatic dishwasher, or if your automatic dishwasher doesn't include a sterilising option, it is especially useful to have a separate sterilizer to ensure your baby feeding supplies are clean and free of germs that could make a baby ill. Sterilised bottles and other feeding supplies are important.

A sterilizer using steam will, over time, accrue a build up of "scale"---the minerals left behind when water evaporates. Keeping your sterilizer free of scale will keep it functioning at its best for many years.

Unlpug your sterilizer and be sure it is completely cool. The sterilizer should be empty of all bottles or other items when you clean it.

Mix about 103ml of plain, white vinegar with about 198gr of cool water. Distilled water is best, but tap water works, too.

Pour the vinegar and water mixture into the sterilizer. Allow it to stand until you see that the scale build-up on the sterilizer has dissolved.

Drain the vinegar and water mixture and rinse with pure water. Wipe dry.

Tip

For most effective functioning, your sterilizer should be cleaned at least every four weeks. To prevent scale build-up in the first place, use only distilled water in your sterilizer.

Warning

To prevent possible burns, make sure your sterilizer is off, unplugged and cool before cleaning.
