Does anyone know anything about using hydrogen peroxide to sanitize the kegs and the lines. I believe it is used in commercial brewing, but don’t know if it is used on a small scale. Hydrogen peroxide is nice to work with and degrades to oxygen and water only which obviously are harmless (I wouldn’t want it to oxidise the beer though). At the biochem lab where my wife works they have moved over to hydrogen peroxide for sterilizing for the same reasons. I believe it would be diluted in water before use similar to Starsan.
So Starsan is great to use and degrades into phosphates which act as a yeast nutrient, so that might be good for the fermenter, but at kegging time, I'm not sure how much yeast activity is going in the keg and how much Left over phosphate I want to drink in my beer:

I've been rinsing the starsan out of my kegs with hot tap water. Haven't had any infection problems doing that. But I still wonder about H2O2.
My conclusion from this thread is that I will gontinue using Starsan with a light hot tap water rinse and watch out for problems. I may try “one step” as a one stage H2O2 no rince cleaner and sanitizer as a time saving measure. I have to look into Iodophor more. Thanks very much for the help.
