Ok, for the stoners out there (no, I mean users of aeration stones with O2), how do you clean and sanitize it? Soak in PBW and then Star San or bake it or what? I had an infected batch that I attributed to the stainless aeration stone I used on successive batches on a single brew day - soaking it in iodophor wasn't enough, evidently that one time (read the last time I used the stone). Just too many bacteria caves in the little bugger for my preferences.
