I normally use a Dr Brown steam steriliser for bottles etc however I’ve been given a Nuby rapid cooler as a gift. Whilst the Nuby flasks can be sterilised in my steam steriliser, the digital lids cannot. The instructions booklet says they’re suitable for cold water sterilisation. I have a packet of Milton sterilising tablets but had a couple of questions on how to do this.
- the tablets say 1tablet to 5l water. As I don’t have a cold water steriliser, am I safe to just fill any big container with 5l water and a tablet and leave the lids in it to sterilise?
- For how long do I give them before they’re sterilised?
We have an all day event out and about coming up next week so would love to make use of these coolers when we’re out so would appreciate any advice
