I use Starsan as my preferred sanitizer, and have had great success with it, not losing one batch to infection since I switched to it. For Christmas, I received a nice growler with a flip top and red rubber gasket. I thoroughly cleaned it, and thought that storing starsan solution in it would mean that when I was ready to fill it, all I would need to do is give it a good shake, and it would be clean and sanitized, ready to accept beer. A couple of months had passed since filling it with starsan solution, and to my surprise, the rubber gasket and flip top was covered in what looked like mold. Was I naive to think that a clean growler filled with a sanitizer would mean that nothing would be growing in it?!?!

Starsan goes inert after a time. If there was crud that the starsan couldn't sanitize before becoming useless then it actually becomes nutrients for nasty, or happy things to grow in.

Best practice would be to first use a cleaner, like oxyclean, then use starsan to sanitize.

Strange...but honestly, starsan is cheap enough where I don't "store" it ever. 1/2 oz for racking/brew days and that it. I know some people store it and it works out fine, but whatever you feel comfortable with is fine. When your ready to fill your growler, just rinse it out to get the dust out, swirl a little SS in it and you're good to go. Plus, its like 1/10th of an oz to thoroughly "swish" out a growler...so that's like what, .25 cents in SS.

starsan is a wet contact sanitizer. Once the area is dry, it's prone to infection again.

yep.. store nothing wet for a long time... leave it open so it dries.. then sanitize right before filling.

Rinse the growler and put it away.

When it's time to fill it, THEN you give it a sanitizing swish.

Starsan is degraded by UV light...at least the commerical stuff we use (Starzene) does rather quickly.

Star-Xene is chlorine dioxide which will degrade when exposed to light.

StarSan is an acid anionic which doesn't care at all if light hits it.

Two completely different products and chemicals.
