PET ODORS DISAPPEAR 2T white vinegar 2T original Listerine 2T hydrogen peroxide 1 tsp dawn 2 cups water Just sprayed it on the area. Used a brush to scrub it in. Then took a damp cloth to wipe and it was totally gone with just a hint of listerine. Through the years have bought enzyme stuff by the gallons due to a male dog who marks. No comparison to expensive store bought product. This combo is it, hands down!
