Cleaning the Nuby Rapidcool

[Greenpanda22]

I love the rapidcool but find it so hard to clean, as you can't properly get to the bottom of it! I use a bottle brush but there always seems to be milk powder residue that I can't reach. Am I missing something or is this a design fault?!

Hot shot method works better if you don’t want to clean it every time

I agree,, hot shot method is what I’ve always used. How do you cope when you’re out for the day? Even just washing/steralising after each use is time consuming. Health visitors approve of the hot shot method, do you know how to do it?
