How to Clean Cat Spray Off Furniture

If you live with a male cat, chances are that he's going to spray the furniture eventually, especially if he's not neutered.

Even if you live with a female cat, you may face the same situation, as females are known to spray when they're feeling particularly territorial. Though the smell of cat spray is pungent and difficult to remove, you can effectively remove cat spray from furniture with some persistence. Once you're done, no one will even be able to tell that your cat sprayed your furniture.

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
  • Bowl
  • Rags
  • 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.


  • If you only partially remove the scent of cat spray from your furniture, your cat is likely to spray there again. Remove the scent fully to ensure your cat doesn't see your furniture as a permanent spot to mark.
