Never used it! It was so expensive- my mother bought one bottle and after that it was right back to the cheap stuff. I am constantly reading articles in scientific journals that say we are herding our kids towards overly sterile environments that will eventually lead to a dangerous inability for their bodies to handle germs. IMO, bring on the pets, normal detergent and dirt!! (Unless of course your child is specifically allergic to something) OR maybe I should just wash the dogs and dust the house!!!
