@scoop for about a year I have been using the microwave sterilizer bags that you can use 20 times then discard. After I use a nebulizer cup in the morning, I take it apart and rinse it thoroughly. I use a second nebulizer cup in the evening and after rinsing that one, I soak both in hot soapy water for 5 minutes and rinse thoroughly. Then I pop all of the parts in the sterilizer bag with 2-3 oz. water and microwave for 3 1/2 minutes.
