Just washed my first batch of ~50 last night in preparation for my first bottling today. Washing soda + soak for a few hours worked great, even for Sam Adams (~25 of those 50), which I understand are fairly difficult to take off. Most of the other labels just sloughed off in the water. A stiff-wire bottle-brush works great for the glue.
Now, the getting rid of the soda part kinda worries me. I'm planning a trip through the dishwasher with a sanitizing steam bath following that. Anyone have any advice on using the dishwasher for bottles?
