Then, for heavenís sake, why switch?

Hehe, well Iím thinking Star-san might be a bit more efficient for 19 liter kegs but the foam may be a bit annoying. I only tend to jodophor bottles (and all other brewing gear of course) not kegs, the kegged beers Iíve brewed were at breweries and not at home.

What about the foaming of the Star-san, for instance?


Iíve heard that Star San can last longer, (particularly if made up with distilled/RO water) but the problem that I have with it is there is no way to know if itís still good other than testing the pH. With iodine solutions (we use Zep-I-Dine) you just have to look at the color to see if itís still good. Super easy. And like you said, itís foams less, though still some, which isnít necessarily a bad thing if you use i for scrubbing.

One downside of iodine is that it stains plastic. But regardless, we use it all the time in the brewery for various sanitation applications. I still have a bottle of starsan at home but I canít see buying more when it runs out. The foam can definitely be annoying in carboys at least.

Thanks for the info, yes Iíve got some discolored things laying around here but that doesnít bother me.

I think heís talking about immediate use - not allowing it to sit for long periods of time. So, if thatís the case, solution strength isnít an issue.

And foamís great - itís what makes the solution so useful. The point is to specifically have the foam cover all surfaces, even those that may have been otherwise missed. Since itís only a light acid and fairly accurately "no rinse," you can pour directly onto the foam and not affect the finished beer. Iodophor on the other hand, when left behind in too great a volume, can affect head retention in the finished beer.

Honestly, peracetic acid is the way to go for brewing sanitation. Nothing has higher kill rates, or a truer "no rinse" quality. But itís too caustic for the applications Iím describing in this thread - SS is gentle, by comparison.

That said, I love iodophor for soaking parts and even carboys (when I know I can really empty them well). But more importantly, Dankoís stressed that heís never had a problem - a sure sign for me that "it ainít broke." So why fix it?
