I use starsan to sanitize jars before making yoghurt for swmbo...much easier than boiling mason jars and it works great.
Two weeks to ferment, two more in the kegs
but in just one night it was drained to the dregs
I use it for Yogurt too
wonder if anyone has used it for a quick shower? just saying, if i thought of it, someone out there (really...out there) has done it
