I have been using iodophor ever since my second batch...But I just realized something. I don't always let it dry.
I know it's a no-rinse sanitizer when at 12.5 ppms, but does it have to dry?
I normally don't let it dry all the way just becaues of time. For instance, I sanitize my primary during the boil, but it's definitely not completely dry when I transfer to it.
