I don't know how many on the forum are brew-masters, but I'm one of them. In addition to making IPAs, Porters, Stouts and other marvelous concoctions, I have to be scrupulous about cleaning and disinfecting brewing equipment and glassware. This is where Star-San comes in. Star-San
is an FDA approved disinfecting acid that leaves surfaces clean and free of bacteria and viruses. It is safe for use on glassware and bottles intended to hold drinks, and is often used in commercial food processing, dairies, kitchens, breweries, restaurants and bars to final rinse vessels, containers, plates, utensils, glasses etc.
Important to note, the dilution of Star-San to water is 1 oz per 5-gallons (1.56 cc/liter). Properly diluted it's safe, but the concentrate is corrosive.
I have been using this in a spray bottle for cleaning the humidifier container, and CPAP hose. It seems to fight mineral deposits, and the funk that can form on the nooks and crannies of the humidifier tray. I don't expect this to become the next sensational cleaner as it's not approved for medical use, but I thought I'd throw this out there for the critics to chew on. Or, if you prefer, I posted this in off-topic, so we can discuss beer.
