I clean fermenters within 30 minutes of emptying them, or I fill with a concentrated PBW mixture to soak if I want a deeper clean. Not many bugs and molds will survive that alkaline environment either!
The bottom line is that Iodophor is more likely to keep mold and spores off your equipment and StarSan doesn't. When I leave my fermenter drained, but still containing the dregs of the last brew, I noticed that there would be spots of mold growing around the yeast ring in the fermenter. Now that I've switched to using Iodophor most of the time, I haven't seen mold in the fermenter. I don't believe I've changed any of my wort, yeast, or other habits, so I believe that the sanitizer change was useful.
