If I clean a smoker and let it sit, I'll get mold, but if I leave it dirty and wait to clean it right before I do my next smoke, no mold., SSo, just drain out the fluids and leave it dirty until right before you next cook. Or, clean it good then fire it up and cook it empty for a few hours at high temp. But then you have to be careful of rust.
