How to Remove Black Pet Urine Stains from Hardwood Floors: 8 Easy Ways

Multiple approaches can potentially remove black pet urine stains from hardwood floors. Which option is best can depend on the size and age of the stain. Fresher, smaller stains are generally easier to deal with than older, larger stains. As a result, they may require fewer harsh chemicals or less manual labor to handle.

However, even if the stain is older, starting with the gentlest option is typically best. Then, work your way up through more aggressive approaches.

If you need to figure out how to remove black pet urine stains from hardwood floors, here are eight easy ways that are worth trying.

Hydrogen PeroxideA convenient option to try for most people involves hydrogen peroxide. It’s a common household item, so there’s a decent chance you already have some available.

The typical household-strength hydrogen peroxide – 3 percent – is what you want to use. If you have a version that’s a higher percentage, you’ll want to dilute it with water before moving forward, bring the mixture down to the 3 percent concentration.

Take a clean, soft cloth and dampen it with hydrogen peroxide. Next, use the cloth to scrub at the black pet urine stain. If it begins to come up immediately, dampen the cloth as needed and continue rubbing until it’s completely removed.

If the stain is stubborn, you can soak the cloth in peroxide and set it on top of the stain. Check it once an hour for up to a few hours to see if there’s any progress. If the stain starts to come up, you can scrub it with the cloth or leave it to soak until the stain is gone. Just keep in mind that lengthy soaking can lead to light-colored stains, so some refinishing may be necessary.

Baking sodaBaking soda is highly absorbent, making it an excellent option for removing excess moisture from materials like wood. If you just discovered the stain and the area is still damp, apply baking soda directly onto the spot and let it sit for several hours, checking it hourly to gauge its progress.

After letting it sit, take a soft cloth and gently rub the baking soda over the area with the stain. Make sure to keep the pressure light. Baking soda is abrasive, so pressing too much can lead to scratches.

If the stain is gone, you can sweep or vacuum up the baking soda since it’s dry material. If the stain is stubborn, you may want to spray the baking soda with white vinegar to up the cleaning power. Then, let it sit for a few minutes before gently rubbing the stain to remove it.

VinegarWhite vinegar has excellent stain-fighting power, making it a solid choice for removing black pet urine stains. Take white vinegar and mix it with warm water, using about one cup of vinegar per gallon. If you’d like, you can add a couple of drops of grapefruit oil to create a fresher scent, but that isn’t required.

Once you have the mixture, dampen a soft cloth with it. Next, gently rub the spot. If it begins to come up, continue that process until it’s completely removed.

If the stain isn’t budging, you can dampen the cloth and let it sit on top of the stain. Check it every 15 minutes to see if there’s any progress. If so, move back to the scrubbing approach. Once you’re no longer making progress, dampen the cloth and let it sit again, going back and forth until the stain is gone.

If you’re dealing with minor, newer pet urine stains, you might be able to remove them with a hand scraper. This process is very manual and requires a delicate hand, ensuring you don’t gouge the floors by mistake.

You’ll apply steady, gentle pressure to the hand scraper. Move it with the grain across the stained area, working to only take up as little of the material as possible. It’s better to work using several shallow passes than one deep one, so keep that in mind.

Once the stained area is removed, you may need to lightly sand the spot. That will depend on whether there are noticeable edges denoting where you scraped material away.

Wood bleach – also called wood brightener – is essentially a lightening agent. Along with removing the wood stain, it can tackle stains caused by other fluids. However, it also can change the color of the wood itself. If you go this route, you’ll need to work carefully.

Since wood bleach can alter the color of wood, you should only try this option for smaller stains. That way, any shift in the hue of the wood may be unnoticeable.

Check the manufacturer’s directions regarding any mixing and application steps. Apply the wood bleach methodically and slowly, ensuring it doesn’t extend beyond the black pet urine stain area. If any wood bleach comes in contact with other areas of your floor, wipe it up immediately.

Sanding and refinishing your floors may be your best choice for larger or deeper stains. It allows you to remove all of the stained wood, giving you a fresh surface.

Whether you sand and refinish a single area or an entire room or flooring run may depend on how deep the stain is and whether you could apply a finish to one spot that matches the rest of your floor. If that’s the case, you can use fine-grit sandpaper – going with the grain – to carefully remove the stain. Then, refinish it to match the rest of the room.

If the area you’re working on would stand out from the rest of the room, you may need to sand and refinish the whole space. Using a floor sander – going with the grain – is usually the fastest option. After sanding, you’ll remove the debris, clean the surface, and then refinish.

However, if sanding and refinishing aren’t in your wheelhouse, you may need help from a professional. Additionally, if your wood flooring isn’t thick enough, this may not be an option. If that’s the case, you may have to replace the damaged boards or the entire floor to deal with the stain.

Remove Urine From Hardwood Floors With Baking Soda

Use a stronger mixture of 3% hydrogen peroxide with a squirt of dish soap and a sprinkle of baking soda. Then wipe the urine and dry it with a soft cloth.

White vinegar is an alternative solution for removing stains and odor caused by animal urine. Chemically, vinegar neutralizes ammonia from animal urine. It also natural and will never harm the environment.

Another layer of coat sealer can also be considered to prevent further damage. These are available in any department stores or hardware shops. Pet shops sells odor remover that also can remove bacteria from urine.
