How to Use Peroxide for Old Urine Stains

Hydrogen peroxide is a powerful and versatile chemical that is commonly used as a cleaning agent. Peroxide can be used either diluted or full strength, and features natural anti-bacterial, anti-mold and anti-mildew properties. This homemade cleaning alternative is optimal for removing stains and odors, and is especially effective for old urine stains on carpet, hard floors, mattresses and upholstery. Whether you are cleaning up after a pet, a young child or an incontinent adult, you will benefit from the cleaning potential of peroxide.

Pets are a major cause of urine stains on furniture and carpets.

Removing Urine Stains From Wood Floors

Step 1

Pour full-strength hydrogen peroxide directly onto the stained area of the wood floor. Use an adequate amount to cover the entire stain and wet the floor without causing a puddle.

Step 2

Soak a clean washcloth with full-strength peroxide. Using a white washcloth is recommended since peroxide may bleach the material. Place the cloth directly on top of the saturated stain.

Step 3

Tear off a large piece of plastic wrap. Place the plastic wrap over the cloth to create a moist, stain-lifting compress. Allow the compress to sit on the old urine stain overnight. This treatment will remove the urine stain, and kill any mold, mildew, bacteria and odors.

Step 4

Remove the compress from the stain. Dampen a clean washcloth with a solution of one part water and one part white vinegar. Thoroughly wipe the floor with the vinegar solution, then dry with a clean cloth.

Removing Urine Stains From Carpet and Upholstery

Step 1

Combine 15 ounces of hydrogen peroxide, 2 tablespoons of baking soda, and two squirts of liquid hand soap. Mix the ingredients together in a large bowl.

Step 2

Test the peroxide solution on an inconspicuous area of the carpet or upholstery before applying, since this process may cause discoloration.

Step 3

Apply the solution to the urine stain using a clean cloth. Thoroughly saturate the area and allow the peroxide to set for approximately 15 minutes. You will notice some fizzing, which is a normal chemical reaction between the bacteria in the urine and the hydrogen peroxide.

Step 4

Blot the wet stain with a white washcloth. Apply pressure while blotting to pull out as much of the urine as possible. Do not scrub the area, since this will only push the stain deeper into the fibers.

Removing Urine Stains From Mattresses

Step 1

Combine 15 ounces of hydrogen peroxide, 2 tablespoons of baking soda, and two squirts of liquid hand soap. Mix the ingredients together in a large bowl.

Step 2

Use a white washcloth to apply the solution to the urine stain. The spot will begin to bubble, indicating the peroxide is working on the stain.

Step 3

Starting from the outer edges, firmly blot the stain and work your way to the center. Apply extra peroxide and continue blotting until the stain is completely gone.

Step 4

Let the mattress to air dry before replacing your bedding.
