I have a 6 month old puppy and we now have drak spots all over the carpet in places that he has peed and we have "cleaned" up with 8in1 Pet Stain remover. It SUCKS! We need a steam cleaner and good pet stain/urine/odor remover that works. Arm& Hammer doesnt work. Resolve is a pain. I need something easy to use and very effective. If it really works I dont care how much money it is. I hate the way my carpets look.
