Amazing product! It actually works. My beautiful boy Labrador had an accident on my rug. I must have missed it as one day the smell was so bad we had to take the rug out of the house. I tried everything I could get my hands on and was recommended but the smell was still so bad. I was just about ready to throw the rug out until I seen and tried the PetLab carpet cleaner. Wow it worked! Not only did the acid smell go, but it left my rug smelling so beautiful and looked so clean. I have never seen it so clean! I use this product all the time now. I have recommended it to everyone I know.
