My go-to. There's no store bought spray I've ever used that adds up to Remove Cat Urine and Dog Urine from carpet quite like this one. Mix 1 part water, and 3 parts vinegar. Spray. Let it soak for 30 minutes. Mix 1 cup of hydrogen peroxide, 2 teaspoons of baking soda, and a squirt of dish-washing liquid. Shake it well. Spray, and let it soak/dry. Adjustments can be made for the measurements, to your liking.
Eco Housekeeping Tip: Pet Odor Eliminator - 1. spray bottle, water, mouthwash, newspaper. 2. combine 2 parts water to 1 part mouthwash 3. spray mixture on soiled area, do not soak. Then place 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.
If traces of urine odor remain on your carpet from an unfortunate accident, that odor may signal to your pet that “This is where you go”. Since many pet urine stains are invisible to the naked eye, you can use a handheld blacklight to spot them. Just turn the lights out and move the blacklight around the room, a few inches above the carpet, until you spot the conspicuous glow of a urine stain. Then tackle the stain immediately.
