In my 10+ years of brewing I've only ever used Star San, the brown stuff, and it works very well. Accidentally, I bought some Saniclean, never used before, and today I sterilized my keg with it before dumping in my beer. It looks gnarly, thick like whale semen, overly foamy, and a faint odor like hand sanitizer. I'm sure it's fine to use, but the obsessive person that I am, I can't help but think that I just put some toxic avenger sludge into my beer. Anyone have a comment on this? Like, "don't worry bro, I drink that stuff with my Lucky Charms, it's fine."
