Blot up any urine with a paper towel if the furniture is still wet.
Combine 1 cup of hydrogen peroxide, a dash of liquid castile soap or dishwashing detergent, and 1 tsp. of baking soda in a bowl. Stir until the baking soda is entirely dissolved.
Apply the mixture liberally to your furniture, allowing it to soak into the upholstery. Because the scent from the spray may have penetrated the area around the visible urine, be sure to treat a wider area than the spray mark itself.
Allow the furniture to dry completely. It will probably take at least 24 hours for it to dry.
Smell the upholstery. If you still catch a whiff of cat spray, repeat Step 2 through 4.
Use white vinegar if you still smell urine after the second treatment. Dilute the vinegar with an equal amount of water and blot it onto your furniture with a rag. Allow it to sit overnight and smell your furniture again. Repeat the vinegar treatment if the smell still lingers.
Things You Will Need
- Paper towels
- Hydrogen peroxide
- Liquid castile soap or dishwashing detergent
- Baking soda
- Vinegar, optional
- Dreft, optional
- Commercial cat urine cleaner, optional
- The sooner you treat the area your cat sprayed, the more effective you'll be at removing the smell. Some people report having success at getting out cat spray with Dreft baby laundry detergent. Mix a cap with two cups of water and apply it to your furniture. Then follow Steps 3 through 5 above. You can purchase a commercial cat urine cleaner, such as Just for Cats by Nature's Miracle or Urine-Off. Homemade cleaners, though, can be just as effective and often more readily at hand. If your neutered male or your female cat continues to spray, discuss the problem with your vet. Persistent spraying can be a sign of a medical or psychological condition.
