I've watched a couple of videos about sanitizing kegs. After cleaning, they show rinsing and then putting StarSan in the keg.. pressurizing and running thru the serving line and then storing like that until ready to fill again.
Is there any issue with doing that with Iodophor? I don't know if there is a long term compatibility issue with the two. I highly doubt it.. but, thought.. better safe than sorry...
