Nuby Rapid Cool Digital Lid

I do the hot shot method so don't have to sterilise it however I have seen you can buy a rapidsterilise lid that sterilises the rapid cool without submerging it.
I'm sure the leaflet with it said to not submerge the lid as it can stop working

I have a Milton cold water steriliser, I put the digital lid in there. The leaflet from the Nuby rapid cool (still on my dining table as we recently bought it!) Says not to submerge in sterilising solution for prolonged periods of time. So we put it in, start a 15 minute (or up to 30 if we get sidetracked!) Timer and then take it out. Just enough time to sterilise and not leave it for prolonged time. So far so good, no concerns with it working or readings.
I guess because the battery isn't replaceable then the lid must be somewhat watertight to prevent water getting in so easily.

I usually do the hot shot method but at the start I used to tip the milk straight in and pour hot water from the kettle into the nuby and on the inside of the lid after washing it and it still works fine.

thank you, we have got some of those steriliser tablets so that’s useful to know that is what you use. Yeah that’s what had read and it makes sense not to have it submerged with the battery but then I wasn’t sure how to sterilise it. But I will do the same and submerge the whole lid but make sure to set a timer for 15 minutes so it isn’t in there too long

I float it in Milton solution for the alloted 15 minutes it takes to sterilise something. I use the hot shot method but still sterilise it every so often.
