I regret that this purchase did not take place to be when you have a dishwasher and cold sterilization products for baby feeding bottles. Once the bottle washed, it must also washed the brush, a sponge than enough but if you hurry! Plastic giving effect a little "cheap" or "toilet brush", thrown away after a month to "non-use". I think we should think about its usefulness in everyday before buying, it was not my case.
