I'm a Vet and have gallons of Betadine, which of course is iodophor. 1/2 oz. per 5 gallon is a no-rinse sanitizer. But you have to make it up fresh every time. When the color fades, it is no longer effective.What ratio of betadine did you use? Any reason you went with betadine as opposed to iodophor? And did you let the bottles air dry before filling? Did you get the Stainless AutoSiphon from BrewSensible? Or just a standard stainless racking cane?
When bottling, I just drop the dishwasher door , set the siphoning bucket on the counter above, and attach the sanitized racking cane. My stainless autosiphon is from BrewSSSential. Got it at Homebrewcon last year. 20 minutes in the oven at 225 sterilizes it. My racking cane is still the standard plastic. I'm going to look into a stainless racking cane.
