Sorry for the newbie question. I'm just trying to figure out if there's some sort of catch here. I don't think the StellarSan stuff is diluted, so I've been trying to figure out how it's so much cheaper than starsan.

Understood. My first thought was actually to check whether the stellarsan stuff used some weird chemical, but the Amazon listing didn't specify what the starsan uses, so I'd assumed it was some secret recipe or something. Thanks

Look at the images online. The packages on both say that they're 50% phosphoric acid. The "Starsan" has another acid at 15%, but it's not likely a differentiator in their performance.

Another thing you can do if you want to know the chemical makeup of something - Ask the MFG for an "MSDS" (Material Safety Datasheet) - it'll generally tell you what it's made up of.

Oh right, thanks again!
