I sprayed this on a spot on our new carpet...I had tried everything--Folex, my Little Green Machine, and NOTHING worked. I saw an ad for My Pet Peed and thought to try it since my stain couldn't get any worse. I sprayed it on heavily, like the bottle said, and just let it sit. As it sat, I could see the stain start to fade and within 24 hours the stain was gone and the carpet was dry. I was very skeptical! I am not a paid spokesperson. I just want to help anyone out there who has tried it all and had no luck. It's well worth a shot because it works!
