Why is using the dishwasher a better idea that Starsan? Seems much faster to just submerge in a bucket for a couple of minutes.
I've heard some horror stories from a local HBS about dishwasher sanitizing. In this case, a guy was having sanitation issues from an unknown source - until they did a culture on the insides of his dishwasher and got all sorts of scary stuff growing on the plate. I'm sure this depends a lot on the dishwasher - is it new, stainless, does it have a real sanitizing cycle?
I'm a bottle-only guy, and have probably capped at least 1200 in the past year. Personally, I soak re-used bottles in oxyclean or PBW for a couple of days, bottle brush as needed, rinse, dry, store, then soak again in a tub of starsan on bottling day. I'll sometimes use the dishwasher to rinse after a cleaning soak, but I always
go with the starsan soak before bottling. I have a classic (non-spraying) bottling tree, and can't imagine bottling without it. The caps are dumped in a bowlful of starsan beside me on the floor, then the fun begins.
