Thank you
You can fill the flask with your sterilising solution, put the lid on and turn it upside down x
Always sterilised mine in the cold water steriliser. Never any issues my end
You can put it all in water. I always sterilised mine in Milton cold water steriliser and it’s fine.
I do mine in the cold water solution for 15 mins including the lids, never had a problem x
You can put the flask in water, just not the lid. When we’re at home if needs be we use our UV steriliser, just wash the flask in warm soapy water and scrub the inside of the lid then sterilize. If you use cold water. You can put the flask in water and we just pour some of the sterilising water into the inside of the lid and let it sit. Alternatively you could use the hot shot method and just put hot water in the flask that way it doesn’t need sterilising as often :) x
