This spray is really a silver bullet. Each patch of organic origin must surrender it. With my first hangover 35 years ago, it stopped me catchment, a friendly staff of the pet shop has recommended it to me then. The spit stains of my little son were just removed as animal blood, urine and feces and vomit. Simple to do, spray, soak and rub out. Voila, that's the whole trick. Gets 5 stars from me is an important household helpers. Does not smell, animals like it too.
