No-Go – Wow!!!!! I mean wow. We have tried EVERYTHING to get get the urine smell out of our carpet and couch. Our 2 male dogs would literally have peeing contests when we go to bed at night. We have tried every expensive carpet treatment out there to no avail. But this stuff actually worked. We can’t believe it. They still pee from time to time not but we can’t believe that we even get nights off. Amazing.
