I got a bunch of empty bottles from friends and I ran them through the dishwasher before spritzing them with iodophor (sprayed at least 5 times using the sanitizer injector). As I was doing that, I later noticed that there was some gunk that the dishwasher didn't clean completely. I wasn't paying close enough attention to see which bottles had the crud in them originally, but my question is, did the iodophor sanitize them well enough? Or am I gonna infected bottles of beer?
