Dishwasher on high heat no detergent. I do it everytime. Never had a problem. Then I dip in a bucket of starsan right before I bottle. Could be overkill but I don't have to worry.
I keep Busch lite stocked in my fridge for my buddies and when I'm in the mood to drink all day. It like 95 calories and IMO way better than Miller Lite. Sounds like my palate may be a bit different than yours. Oh, and its super cheap. Good Luck
