There is one thing that I do, not seen anywhere else on any site. In regards to storing neb cup parts in between uses. After washing in soapy water I set them on a paper towel to dry for about 1/2-1 hr them store them in an airtight rubbermaid container also sitting on top of a paper towel but in addition I place a 5G desiccant package (Amazon) under the paper. If the parts are not completely dry when put in, they are bone dry for the next use. I put in a fresh desiccant package once weekly on the day I boil the parts for 10 minutes. Bill
