I am in awe! We have vertical blinds over a sliding glass door. We got a new puppy and after he learned to hike his leg to pee he started doing it on the blinds. He is not a small dog so the pee stains were about a foot off the floor and had run down. Sprayed the blinds today then opened them. Closed the blinds again a few minutes ago. The stains were completely gone! Still not believing what I am seeing!
