We scrub w/hot water & soap, then 'sterilize' in the dishwasher each night. We also replace nebs each 6mo. Seems to have worked thus far but we'd obviously like to do better.
So I boiled a neb and destroyed it last Spring - been pretty hesitant to try again. The method seems so simple except that, again, the neb was warped and ruined by the boiling water. Don't know if this has happened to anyone else. Any ideas on boiling 'technique' as I'd definitely like to give it another shot?
