How to Make a Cat Pee Remover From Hydrogen Peroxide

"What do you mean the carpet smells?"

"What do you mean the carpet smells?"

You love your kitty with all your heart, but the odor from her urine is something that your nose just can’t get past. While many commercial urine stain and odor products are available, a homemade treatment solution using hydrogen peroxide helps clear the air and reduces repeat accidents.

Locate all the urine spots on your carpets. While your bare feet are sure to find the fresh, wet spots, finding older spots requires a different approach. You can choose to go the bloodhound route and get down on all fours and sniff out the offending areas, however, your nose may argue against this option. Your other choice allows you to channel your inner crime scene investigator. Turn all the lights out and turn on the black light. Those old urine spots will take on a glow and show you right where they are.

Blot up any fresh urine spots with a paper towel or old cloth. Do not rub the spot, as this will spread the urine and the smell. Continue blotting until a fresh piece of paper towel comes up dry.

Mix a solution of equal parts water and white vinegar in a mixing bowl. Pour this solution onto the urine spots and allow it to sit and penetrate the carpet fibers for at least 15 minutes. Make sure you pour enough liquid onto each spot so that the mixture penetrates down to the bottom fibers. Blot the liquid up with paper towels as you did with the wet urine spot. Continue until all liquid is absorbed.

Cover the spot with a layer of baking soda. In a small bowl, mix 3/4 cup hydrogen peroxide with 1 teaspoon of dishwashing detergent. Slowly pour the solution over the baking soda. When the two mix, bubbles will appear. Use the scrub brush to work the solution into the carpet fibers. Let the mixture dry overnight. In the morning, vacuum the remaining powder. Repeat the steps until the odor is gone.

Items you will need

  • Black light (optional)
  • Paper towel or old cloth
  • White vinegar
  • Mixing bowls
  • Baking soda
  • 3 percent hydrogen peroxide
  • Dishwashing detergent
  • Scrub brush or old toothbrush
  • Plastic spray bottle (optional)


  • To treat stains and odor on concrete or other hard floors, mix two drops of dishwashing detergent with 2 cups hydrogen peroxide and 2 teaspoons of baking soda. Place all ingredients into a spray bottle and gently mix until the baking soda dissolves. Spray the mixture directly on the urine spots and allow to dry overnight. The mixture is freshest and most effective when used within an hour of mixing.


  • Before using hydrogen peroxide to treat urine stains on carpet, test a hidden area to make sure it will not remove the color in your carpet. While the odor is offensive, a polka dot carpet may not be the look you are going for. You may need to try another odor elimination method.
