NEW YORK -- I purchased 8-1 complete pet stain remover, to of course remove a pet stain from my carpet. When I used it, it removed the stain, but left my living room carpet with three large white spots. I called the company, and they said "Sorry there is nothing we can do for you." This product stinks, and so the customer service dept. Don't buy this product, or you'll be stuck with a carpet like mine with large white stains.
