The 3 Homemade Solutions to Get Rid of Cat Urine Odor

1. Hydrogen Peroxide, Dish Soap, and Baking Soda

You probably already know that hydrogen peroxide is excellent for killing odors and fighting bacteria. If you combine it with dish soap, then it makes an excellent odor eliminator. However, it is important to note that hydrogen peroxide can discolor certain types of materials, so you’ll want to try it out on a small area that’s hidden from sight on what you’re cleaning first.

For this solution, you fill a spray bottle with hydrogen peroxide, then add a few drops of dish soap. Spray the solution directly on the old cat urine area. Blot the area gently with a cloth or paper towel to remove as much of the old urine as possible.

Sprinkle baking soda over the spot to dry the solution and pull out the odors, then let dry.

Once this is done, sprinkle some more baking soda on the spot, let it sit for a few minutes, then vacuum as you normally would. Between the hydrogen peroxide and the baking soda, the area should smell fresh and clean when you’re done.

  • Easy to use
  • Can be used with other DIY remedies
  • Takes 3–4 hours to dry
  • Can discolor certain materials

2. Club Soda

Believe it or not, club soda is the perfect tool for removing old cat urine odors from your home. Simply pour some club soda on the stain, then let it fizz. Once the fizzing stops, blot the remaining club soda up until it comes out of the carpet.

Once the area is completely dry, sprinkle baking soda across the area and let it dry for 30 minutes or longer to remove any lingering odors. Vacuum as usual at the end of that time.

As with any other DIY option out there, this isn’t guaranteed to work on all stains, but it is a natural remedy and pet-safe as well.

  • Easy to use
  • Pet-safe
  • May not work on all stains.

3. Vinegar and Water

Vinegar and water have long with a DIY solution for many cleaning and removal projects. In this case, the vinegar works to counteract and remove the odor from the old urine stains. It’s easy to use and can be used not only on most surfaces but in the laundry as well.

It’s best to mix 50% water and 50% vinegar. First, mix it all in a spray bottle, then spray it on the affected area. Finally, mop up the entire solution with a cloth, and let the area dry for the best results.

  • Easy to use
  • Can be used on most surfaces and in the laundry
  • Must be mixed
  • Must be left to dry
