Things To Prepare Before Removing Black Urine Stains From Hardwood Floors

When properly cared for, hardwood floors provide beauty, warmth, and value to a house. Although wooden floors are typically strong and lasting, they are sensitive to water, humidity, or harsh cleaning products such as dish soap.

Grime and filth, pet urine, or mold are common causes of black stains on hardwood floors. In the case of grime and filth, a lack of regular care can contribute to the severity of the stain by enabling dust and dirt to accumulate on your floor and allowing mold to develop unchecked. In most situations, the longer you leave the stain, the more difficult it is to remove.


To remove successfully black urine stains from hardwood floors, here’s what you need:

  • Hydrogen Peroxide
  • Water
  • A scrubber or a piece of cloth
  • Paper towel

3 Steps To Remove Black Urine Stains From Hardwood Floors

1. Use Hydrogen Peroxide to clean the stained areas of the floor

The first step is to identify the affected areas. Then, you will apply your hydrogen peroxide directly to these spots. 

This step requires considerable accuracy and attention to detail. You do not want to apply or spray the solution all over the floor. All you have to do is spray it directly on the stained spots.


If you made mistakes and sprayed on unstained areas, do well to wipe off the over-spills to prevent the floor from being bleached.

When you have confirmed that the hydrogen peroxide has been spread evenly, use a paper towel to cover the discolored areas that you have applied the hydrogen peroxide on.

Allow the solution to remain for a few minutes before removing it.

2. Examine the area

Don’t think that the stained spots have magically disappeared. While hydrogen peroxide is good at removing black stains from flooring, it does not do so automatically.

Therefore, you must constantly examine and survey the affected areas to track how the solution affects them.

Pick up the paper towel at regular intervals to observe if the original color of the floor returns.

One way to tell is to look at how dark the stains on the paper towel have grown. The general rule is that the darker the stains on the paper towel, the lighter the black spots on the floor.

It will just take a few hours for most of the stains to be erased from the hardwood floor.

3. Clean the area

Cleaning the affected areas with clean water is the final step in determining the degree of the black stain removal.

Take note of the water’s color. If it remains darker than expected, it indicates that the black spots are still visible on the surface. So it would help if you used more force to scrub them off.

Otherwise, simply clean the entire surface until it shines and your floor begins to regain its texture and rich appearance.


Other Methods (Apart From Hydrogen Peroxide) To Remove Black Stains From Hardwood Floors

Baking soda will function as a cleaning agent as well as a deodorizer in this approach. Baking soda usually works best when combined with vinegar. Consequently, you will want the assistance of white vinegar when carrying out this cleaning technique. These two stain removers, when used together, can remove heavy urine stains from your magnificent hardwood floors.


Here’s how you can do it:

  1. Combine the two ingredients to make a paste-like combination of baking soda and distilled white vinegar, 
  2. Coat the discolored area with the mixture. Allow it to sit for an hour.
  3. With a microfiber towel, remove the remaining baking soda and vinegar coating and discard it.
  4. Allow it to dry after wiping the area with a wet towel.

Enzymatic cleaner

Enzymatic cleaners are non-toxic commercial products that employ natural enzymes to neutralize urine, causing the stain to vanish. This approach accelerates the stain removal process, although it may need to be done several times if working on old, persistent, or dark urine stains.

When cleaning dark urine stains using commercial enzymatic cleaners, use these steps:

  1. Firstly, clean the stained area’s surface like any other method.
  2. Apply the enzymatic cleaner to the urine-stained areas.
  3. Following procedures may differ based on the manufacturer’s instructions. Therefore, when using the product, make sure to read the directions thoroughly.
  4. After the stains have faded, clean the area with water and allow it to dry.
