I am into my second batch, and I have been using bleach and also a powdered sanitizer (not sure the name, came with kit, but positively states it is a sanitizer). Everything gets soaked in a warm bleach solution to kill anything off, then things like airlocks, stoppers, spoons, thermometers, etc get rinsed with, and then stored in warm boiled water w/ a sealed top. When I bottle, I wash, soak everything in a mild bleach solution, dunk in warm boiled water, and then quickly in a mild no rinse sanitizer made with boiled water- no real chemical to speak of, and my first batch tasted great. Sounds like a lot, but actually, I do a lot of the bottle prework prior to bottling night, and when brewing, I just put a couple pots of water on to boil 1-2 hours before I start, and leave them capped. It really doesn't slow me down at all, and I know that everything that was bleached was then hit again.
