Hi, can anyone tell me how you're meant to clean inside an Avent steriliser? I was given one with no instructions nad although I've had it for a few months I've never cleaned it (I hardly use it though- just for bowls and spoons occasionally as I usually just use boiling water) DD is now using a cup and more bowls etc so I'd like to use it a bit more until she's a bit older so how do I do it? I remember reading somewhere on it to use cold water tablets or something (sorry a bit vague) so can anyone advise?
Thanks
