I have a giant tupperware tub. I find it easiest to mix soap and amonia with the water and let it soak. Then take a green scrubby and basically shuck the losened label and it's glue from each bottle. It is a pain but in the end I have a bottle that only needs to go through the diswasher. My usual process anyway as the dishwasher is hot enough to sanitize and a quick load only takes about 45 min. I can fit about 2 cases in the dishwasher.
