I honestly wouldn’t brew without StarSan. I can’t imagine having to sanitize without it. I use a spray bottle and the stuff seems to go everywhere, so I am actually scared of the iodine based cleaners. I do tend to up the concentration on spray bottles. The thought being I am often spraying wet things which will dilute on surface. I had a bottle tip and leak a couple of months ago and at full concentration it etched the concrete in my garage. Otherwise love the stuff.
