Pet Odor Eliminator 1. Supplies: Empty spray bottle, water, mouthwash, newspaper. 2. In an empty spray bottle combine 2 parts water to 1 part mouthwash. 3. Spray mixture on whatever upholstery is soiled (It does not need to be soaked. A little goes a long way). Lay newspaper over the sprayed area & let dry. The newspaper will absorb the smell. Repeat if necessary. Your cushions or carpet may smell minty fresh, but once it wears off the urine smell will be gone. (source was broken)
