My first 5 gallon batch, I used StarSan to sanitize my bottles. De-labeled with a hot water and detergent soak, washed them out with PBW, rinsed them out with clean water, then poured sanitizer into each bottle. I had to handle each bottle at least 4 times, NOT counting the delabeling part. What a pain.
My next two 5 gallon batches (both bottled this week) I used the dishwasher. I had to de-label about 30 more bottles. I made sure all of them were thouroughly rinsed out and clean as soon as they were empty, and I stored them upside down in 12-pack boxes so they'd stay that way. Come bottling day, I filled the dishwasher with bottles (held exactly 48 at a time!), and ran them through a "Hi-Temp wash, Sani-Rinse, and Heated-Dry" cycle. Took about an hour. Then I cracked the door to let them cool off. I figured since they're still upsidedown, they wouldn't get recontaminated. Once they were cool, I just pulled them out one at a time, and used the dishwasher door as my bottling platform.
On bottling day, I only had to handle each bottle once using this procedure before putting beer into the bottle.
I had thoughts about getting one of those squirt-the-sanitizer-into-the-bottle thingamagigs, but now I've changed my mind. I'm even wondering now if kegging would really save me that much more time.
Here they are, 96 bottles of malty goodness:
