How to Remove Black Urine Stains from Hardwood Floors

What is the Reason Behind the Black Urine Stains on Wood Flooring?

Black Urine Stains in Hardwood Floors

First of all, it’s important to understand why hardwood floors get discolored. Urine is composed of water, urea, uric acid, salt, and other chemical compounds. Over time, this mixture evaporates, leaving behind a sticky residue on hardwood floors – resulting in those unsightly black stains.

What is the best way to remove black urine stains from hardwood floors?

There are a few different methods that you can try, but we recommend starting with the simplest one.

Method 1: Warm Water and White Vinegar

Mixed to form a paste, the vinegar will help lift the black stains without ruining the finish on your gorgeous hardwood floors. You’ll simply need two clean cloths to wipe and another for your cleaning solution.

Wet the cloth with the vinegar and wring out any excess liquid. Rub the paste onto the black urine stain and let it sit for a few minutes. Then use the other cloth to wipe the area dry.

Method 2: Hydrogen Peroxide

Hydrogen peroxide is a great way to flush out stains from your hardwood floors, but it can also lighten the wood’s finish if you’re not careful. So be sure to test it out in an inconspicuous spot before using it on the entire floor. If you’re worried about staining your skin, just wear rubber gloves while applying it to the stains.

First, pour a generous amount of hydrogen peroxide onto one of the clean cloths. Next, apply it to the black urine stains and let sit for a few minutes. Finally, use the other cloth to wipe the area dry.

Method 3: Baking Soda

This is a great method to use if the other two methods don’t work or if you’re trying to remove black urine stains from an extensive area.

Simply sprinkle some baking soda on a clean cloth and scrub the black stains with it. Then use a different cloth to wipe away any residue from the baking soda.

Method 4: Commercial Cleaners

If you’re trying to remove black urine stains from hardwood floors, you mustn’t use products with abrasives. For example, Comet or Ajax contain abrasives that can permanently damage the finish of your hardwood flooring. So it’s best to use a commercial cleaner specifically designed for hardwood floors.

Here are some products that you can use to clean the black urine stains on your hardwood flooring:

Just read the directions carefully and test it out in an inconspicuous spot before using it on the entire floor.

Method 5: Steam Cleaning

Steam cleaning is a great way to remove deep-set stains from your hardwood floors. Plus, it’s an effective way to kill any bacteria or germs that might be lingering on the surface of your floors.

In any case, it’s always a good idea to consult with a professional hardwood flooring installer before attempting to clean your floors yourself. They’ll be able to advise you on the best methods and products to use, and they may even be able to take care of the cleaning for you.


How do I prevent this from happening again?

To prevent re-soiling your hardwood flooring, it’s best to use a rug or mat in the area where your pet will urinate. This will help to absorb any moisture and keep it from seeping into the wood flooring below. If your pet urinates anywhere else in the house, be sure to clean it up immediately.

How do I get rid of the smell?

As you probably already know, pet urine has an extremely strong odor. So to get rid of it altogether, the area will need to be deodorized. There are a variety of commercial cleaners that can help to do this, but you can also use baking soda – just be sure to let it sit for a few days before vacuuming it up.

How long does it take for the black stains to fade?

Some of these urine stains can take a very long time to fade, especially deep-seated ones. So don’t be discouraged if the stains don’t disappear immediately. With time and patience, they will eventually fade away.

Does vacuuming help?

Yes. As mentioned above, you should be using a rug or mat in the area where your pet has urinated to help absorb any moisture. But this is also a good time to vacuum up any loose debris that might be stuck in the crevices of the floorboards.

Does steam cleaning help?

It depends. If dried remnants of urine cause the black urine stains, then steam cleaning can effectively remove them. But if new urine stains cause them, then the steam cleaning will probably have little effect. However, steam may discolor your hardwood floors if it’s too hot, so be sure to consult with a professional before attempting this method.

Final Thought

At the end of the day, black urine stains on hardwood floors can be a real pain to deal with, but with the right tips and tricks, it’s doable. So don’t hesitate to give one of these methods a shot, and hopefully, you’ll be able to restore your gorgeous hardwood floors back to their original luster.
