How to Remove Black Urine Stains from Hardwood Floors

The best part is- most of the cleaning methods are DIY and they bring no damage to your hardwood surface.

So, let’s discover the DIY hardwood cleaning tricks.

8 Effective Ways to Remove Black Urine Stains from Hardwood Surface

From this chapter, we break down effective cleaning methods that help to eliminate animal urine and water stains too. Now, let’s go to the point directly.

1. Solution of Hydrogen Peroxide and Water

Applying the solution of hydrogen peroxide and water is the most efficient way to clean black stains on wood.

To make the formula, pour a gallon of water in a bucket and mix 3% of hydrogen peroxide.

Then, dip a soft microfiber cloth into the solution and apply it on the affected area. Leave it for a few hours to sit on the spot. It helps to dissolve the dirt formed by urine.

Next, use a soft cloth to wipe away the area to remove the dark spot and odor from your hardwood surface. And then, let the flooring dry.

2. Use Hand Scrapers

You can hand scrape the area if the urine stains are small and fresh. Make sure you scrape with the grain if you want to apply the hand scraper.

However, we recommend you not to scrape the area deeply. Otherwise, a nasty divot will form.

In any home improvement store, you can find the hand scrapers.

Trying out the hand scraper may mark the floor. So, remove the mark by hand sanding over the area using grit papers.

Lastly, clean the area with a shop vac and seal the area with a surface finish.

3. Try out baking soda

Baking soda is another home cleaning product you can use to remove the stains by pet urines. This ingredient can absorb the liquid from the wood surface evenly. Therefore, it can also remove the foul odor.

Wipe away the ingredients like baking soda once the dirt and the urine smell are removed out.

Then, make a solution of hydrogen peroxide, baking soda, and dish soap. Apply on the affected area and let it sit by leaving it for a few minutes.

Finally, brush away the pet urine and use a soft microfiber cloth to dry the area.

4. Apply vinegar

White vinegar is another effective cleaning ingredient to remove the animal urines and stains.

The acid contained in the vinegar helps to dissolve the dirt. It also removes the strong smells efficiently.

And the best part is- vinegar is friendly to the environment as it’s natural.

First off, make a solution with water and vinegar. Then, apply it to the stained area and let it sit. Secondly, use a soft cloth to wipe away the leftover.

5. Try wood bleach products

Using wood bleach is also effective to remove pet urine stains. But the fact is- you can suck away only lighter animal stains from the hardwood floor.

The wood bleach works the best if you sand the affected area first. It lets the bleach penetrate the wood and removes out the black urine spot.

Before using it, make sure you wear gloves and open the window to ventilate the room. Maintain the safety precautions written on its pack.

6. Sand and refinish the area

Sanding and refinishing is another way to get rid of the stains formed by pet urines.

You can remove every speck of dirt by sanding the wood a bit deep if the stain is not stubborn.

Make sure the area you sand to suck away the stains match with the surrounding area. Otherwise, anyone can notice the area which decreases the beauty of your wood floor.

But the downside of sanding is- it would not remove the foul odor. In this case, we suggest you apply odor cleaner ingredients to eliminate the smell.

7. Cleaning black urine stains using Dish Soap

The dish soap cleaning method is most effective for greasy hardwood floors. First, you’ve to prepare a mixture and start cleaning right after that.

Prepare mixture:

Get some warm water in a bowl and mix it with dish soap properly. For better cleansing, you can add about 3% hydrogen peroxide as well. Also, baking soda with dish soap and water works very well. 

Clean it out:

  • Get a cotton cloth or sponge to soak the mixture and clean the urine stains from the hardwood. Be aware while choosing the sponge/cloth as it should not hold excess water.
  • Wipe throughout all the stained areas.
  • Give the cleaning five minutes and it can certainly soak out the greasiness.
  • Now grab a dry cotton cloth and make sure there is no excess water over the flooring. 

8. Using commercial Cleaner(Enzyme Cleaner & Others)

Black urine stains are certainly stubborn and take a lot of time to clean out. You can get a lot of commercial cleaner options in different budget ranges in the market. Although such a cleanser might cost you some bucks, you can clean out using these very fast. Professionals usually suggest using an Enzyme cleaner. The enzyme has such substances to break down uric acid and turn it into carbon dioxide and ammonia. It will easily remove stains along with nasty smells. But make sure you’re getting a good quality enzyme commercial cleaner.

Apply the cleaner:

  • Pour enzyme cleaner over the stained areas.
  • Give the cleaner at least 15 minutes to sit and work effectively over the stained areas.
  • Now bolt up the Enzyme cleaner thoroughly.
  • Get the area’s air circulation as it should be air-dried.

Note: For an effective commercial cleanser, instructions are written over the packaging. It will be safer as well as more effective.

    1. Thanks Maureen McBride,
      If you have a black stain on oak wood, it is likely caused by a combination of water and soil. To remove the stain you should first mix a solution of one part bleach and two parts water. Soak a rag with the solution and apply it to the stained portion of the wood. Allow it to sit for ten minutes before wiping off with clean water.
