This spray is nothing short of amazing!! My dog had quite a few "accidents" during my recovery from hip surgery. I could smell urine all the time. I bought this after watching the informative video and I must admit, I was skeptical. I used it as directed and not only did it get rid of the odor, the stains vanished!!! I even used it on a few stains from spills and it worked on those as well! Truly a miracle product and I highly recommend it!
