So what I ended up doing was
- hour or two soak of bottles in hot water and washing soda the night before bottling
- easily peel off labels while soaking, scrub any remaining residue with bottle brush
- soak in bleach for fifteen minutes the morning of
- rinse a few times and throw em in the dishwasher
- cook in the dishwasher on antibacterial setting and heated dry
- bottle directly from dishwasher
The dishwasher option almost seemed like overkill at that point, especially with the 2-hour+ cooking time... but, since it was my first time, I was willing to err a bit on the side of paranoia so as to get a better feel for true tastes in my finished product.
Bottling over the dishwasher was a good idea. I looked at my dad's (a winemaker) bottle-filling gun just before using it (and after soaking in bleach solution) and realized it was completely gunked up, so I bottled with just a tube and my fingers to clamp. The dishwasher door served its purpose.
I'm getting tired of bleach. I want my kitchen smelling like a brewery, not an especially-clean bathroom. If I do Iodophor next time, I'll probably just give em a pull on the bottle-sanitizer the morning of and throw em on the bottle-tree to dry. Still will probably use the dishwasher door to bottle over, just not use the dishwasher to clean the bottles.
