Keeping Baby Bottles Clean

If you are bottle feeding your baby, then one of your main priorities is to keep the bottles as clean as possible. This is important as it will prevent bacteria, viruses and disease getting into your child’s system and potentially making them very poorly. Here are some tips on how to keep bottles sanitary.

Wash them thoroughly

Before bottles can be sterilized it is important that they are thoroughly washed first. A quick rinse is not enough. They should be washed in hot soapy water and and residue of milk needs to be removed from the inside of the bottles and the teats. A bottle brush is the best tool to use for this. Caps and lids should also be thoroughly washed before adding to the sterilizer.

Clean them immediately

It is also important to clean bottles as soon as you have finished with them and not leave them lying around the house. This will reduce the amount of bacteria that builds up inside the bottles.


There are three types of sterilizer to choose from; cold water, electric or microwave. A cold water sterilizer will need sterilizing fluid or tablets while the other two work using steam to kill the bacteria. It is essential that you follow the instructions that come with the sterilizer to make sure that your bottles are sterilized for long enough before you use them.

Use straight away

Once you have removed the bottles from the sterilizer they should be used straight away. The longer they are out of the sterilizer for, the longer they have to collect bacteria. If you prepare several bottles in advance you should put the lids on and store the bottles in the refrigerator until you are ready to use them. This will minimize the likelihood of bacteria collecting in the bottles and being passed on to your baby.

Change sterilizing fluid regularly

If you are using a cold water sterilizing unit then the sterilizing fluid needs to be changed on a regular basis. As a general rule, it should be changed at least every 24 hours. This is because each time bottles are added to the sterilizing fluid they will introduce some bacteria. Although the sterilizing fluid will kill most bacteria it is possible that small amounts will remain. Also, if left, water will become stagnant.

Appropriate storage

Once bottles are filled with milk it is important to store them properly until they are used. The best place to keep the bottles is in a refrigerator and they should be consumed within 24 hours. If you are going out for the day a good option is to buy ready made cartons of milk rather than preparing the milk in advance. This will solve the problem of keeping the bottles at a safe and sanitary temperature until they are used.

Sterilizing bottles is an important part of your role as a parent. Making sure that bottles are sanitary is simple to do if you follow some of the aforementioned tips and this will help to keep your baby healthy.
