I just spent the weekend cleaning out 150+ nasty bottles, hand scrubbing each until I had an epiphany: my drill. I soaked in oxi overnight, then put my bottle brush in my cordless drill to quickly scrub each bottle; I ended maybe 5 seconds each once I got into the rhythm. Afterwards they went back in for a second oxi soak, then warm water rinse and a run through the dishwasher with no soap. They're good as new.
Try out the bottle-brush-in-a-drill, it really works!
