A baby bottle sterilizer has changed my life in terms of sterilizing. It's so easy. It heats for 8+ minutes over 212F and then dries the stuff. After soaking the aerobika and nebulizer in hot soapy tap water and rinsing, I pop it in the sterilizer. For the sterilizer I use distilled water so I do not get mineral buildup. I have two aerobikas and two nebulizers so both are used once and then sterilized at the end of the day.
