Hello, my "golden rule" was 24 hours maximum, and even then make sure it's in a fridge or kept very cold for that time.

Once sterilised (if using microwave steriliser) it will remain sterilise for 24 hours if remain in the steriliser and the lid has not been opened. Once opened the bottle will only be sterilised for 3 hours.

I think you will find they remain completely sterile for 3 hours in the steriliser as long as it remains unopened and then they are ok for 24 hours once all the bits have been assembled
