I'll stick with my i-o-dine, tenk you veddy much:) He does say something about "when other avenues are exhausted" or some such. I dunno, though. Chlorine? Isn't that bleach? Whatever. I distrust anything that has "miracle" in the name. And "mineral" when there ain't none(minerals). Double lie. Mah grandpappy taught me to read the signs, that's a baaaaad sign:)
