The Natures Miracle Urine Destroyer Dog is an enzymatic formula that begins to break down and remove stains immediately on contact. This powerful formula is just soaked into the affected area, allowed to work for 15 minutes, and then blotted up with a clean cloth. The Natures Miracle Urine Destroyer Dog continues working as long as any bio-based mess is still present. It is also safe for use around your pets and in your home.
