That is way over kill. Beer bottles do not need to be sterile. They need to be sanitized. The water in the dishwasher is hot enough to kill any bacteria.
Let them soak in water/oxyclean to loosen up and sediment, let them dry, then just put them in the dishwasher with no soap, and run it. That will rinse and sanitize in one step. With no work.
oxy-clean soak, and a metal pad to rub off excess goo.
O'fallon brewery labels would not come off for anything. They are the only ones I have ever had a problem with.
I use a stir stick. I think it's supposed to be for wine. It goes in the end of a drill, and you just stick it in the carboy and stir it up. No worry about dropping a carboy, or making a mess.
