This stuff is amazing. I have white carpet in my bedroom and a few years ago my furry four legged child became ill, the medications she was required to take caused a few accidents. I have bought every pet stain remover out there . I also have a very expensive, top of the line steam carpet cleaner.Then befote I knew it, the stains aways returned. How could this keep happening , so I got one of those blacklights. To my surprise after treating the stain and finishing with a steam cleaning, the stain was still there under the blacklight. Glowed like a Christmas tree.Then I saw this Oreck dry carpet cleaning kit.I already own the orbiter , which I love so I desided to give it a try.WOW , STAINS ARE GONE !!!!! Its been over a month and carpet still look brand new. Not sure how it works but it does . Nothen glows under blacklight...Wish I had this years ago, easy to use and the only thing that permanently removes stains !!!!
