    iodine for sanitizing???

    I bought a bottle of providone-iodine 10% from Wal-Mart earlier. Is this the stuff I need to use for sanitizing. Also how much do I use?

    I know Iodine is the sanitizer in Iodophor, but I am very nervous about recommending dilution strengths. Iodine IS a poison in excess amounts. The problem is that I don't know what constitutes "excess".

    A far easier and safer way to go is to get a bottle of Star-San. It is food grade phosphoric acid and the easiest, most widely used sanitizer out there.
    (If you look at the ingredients on most soda pops, phosphoric acid is found there.)

    To add to what Brewdog said, a lot of people use Idophor which is a food grade sanitizer used in the dairy industry. It is a mixture of iodine and phosphoric acid. It works well.

    Save that iodine you bought from Walmart for boo-boos.

    You can get either star san or idophor at your lhbs. if you don't have one nearby, you can find idophor at any farm supply store that has dairy supplies.

    That's good to know about the dairy stores. Believe it or not this corner of New Mexico is bigtime dairy country. In fact I was thinking this morning about trying to get some used dairy equipment for fermenters.

    It only requires a 2 minute contact, no rinsing and I use 1 cap full for 5 gal of water.

    Don't fear the foam with StarSan. I know it's hard to see a huge wad of foam in the fermenter, bottle or keg but it doesn't affect the beer. Don't rinse it out, it will defeat the purpose of a no rinse sanitizer. And you don't have to fill the vessel completely, a gallon solution will sanitize a 6.5 gallon carboy by just shaking it so that the entire inside is coated. Turn it upside down so the liquid runs out and leave it alone. Same for bottles or kegs,

    Thanks bro. I appreciate the help. I have forgot so much about this hobby that I am ashamed to think about it. Is there such thing as a born again newbie?

    Can I change my screen name? I think "dontfearthefoam" would sum up my sanitary practices.
    Boostn--While brewing, I have a 5 gallon bucket with 2 gallons of water and a half ounce of star san standing by. I routinely put my hands in it (OCD) and soak and scrub my gear. I don't use the 2 minute submersion method always, especially with glass carboys, I just rinse them well. Some folks like John Palmer suggest 30 seconds contact time and others just say contact is good enough. Everything I use to brew, preboil and postboil gets a star san bath either before or after the brew ritual.
    I still haven't figured out anything clever to write down here.
