After seeing this on a Facebook ad, I bought this out of desperation. I didn’t expect it to really work. We had a cat who got a UTI during a move and in the new house peed on a fairly new couch…. Which then attracted the puppy… I tried every pet odor remover out there. Nothing eliminated it totally. 24 hours after spraying it down with this, there is no odor and no remnants of a stain. It seems to work exactly like they say. I recommend their black light because it really did help us identify every spot. For those wondering yes it works for any pet stain, puppies too. I don’t normally take time to review stuff like this but I was truly amazed. Worth every penny.
