Ive been using SO2 as a sanitizer ( Potassium Metabisulphite) for making wine for 12 years now. I clean with tons of hot water using special bottle washer then I rinse with SO2. I don't rinse after that, just put them in the drying tower. Whats a standard practice for beer. Would leaving the SO2 kill the priming action??

So for batches smaller than this Campden tablets are normally used.

But what that is talking about is adding the potassium metabisulphite in with the wine or beer as an additive. I'm sure rinsing with it would be fine since I doubt it would kill the yeast with such a small quantity of it.
