Remove cat urine on furniture!! 1 qt. 3% hydrogen peroxide 1/4 C. baking soda 1 tsp.liquid dish soap I mixed the ingredients together and covered the affected areas with the recipe. I took the covers off the cushions and douched the stain with this mix. I poured this mix over the stained area on the Styrofoam cushion under the seat covers too. I had leftovers so I saved it for future pet messes. Then, I let everything air dry over night. There was some baking soda residue on the area but I brushed it off with a paper towel. The cat urine smell was GONE though!
