The reason for my previous post is there appears to be some
misconception about santizers in the home brewing scene.

They tend not to use SO2 because some feel it is ineffective due to
winemakers saying it will not sanitize a wine must, plus all of the bad
press sulfites get. This is true because of the limit on how much
sulfite we add to the must. In the concentration used in a sanitizing
solution, it is very effective.

Idophor is commonly used as a no rinse santizer in homebrewing at 12.5
ppm. To me this is just plain wrong. I'm much more comfortable using
sulfite solution as a no rinse sanitizer than Idophor because I know
the sulfite will not harm the beer/wine. It may even have some benefit
due to it's antioxidant properties and the way it can bind to other
chemicals (like chlorine) than can cause other problems.

Star San is an acid based sanitizer and I don't see any real problem
using it as no rinse, but I'm not sure exactly what else is in there
besides acid. It tends to foam up so I'm guessing that it's not just an
acid solution.
