How to Repair Hardwood Floors with Pet Stains

By Cezar

Pet stains on hardwood floors can pose a more significant problem than initially perceived. Over time, pet urine undergoes a transformation into ammonia, which gradually eats away at the hardwood. Although it may seem unbelievable, this unfortunate truth highlights the urgency of addressing the issue promptly.

The extent of the necessary measures depends on the duration the stains have been present. If the stains are relatively recent, the cleaning process can be relatively straightforward. However, if the stains have had time to seep into the wood, refinishing the hardwood might be required.

In this article, we provide comprehensive guidance on how to handle pet stains on hardwood floors.

Preventing Pet Stains and Wear on Wood Floors

  • Consistent Grooming

Regular grooming is essential for pets’ overall well-being and can help minimize the mess they create on wood floors. By keeping your pets clean and well-groomed, you reduce the chances of dirt, oils, and hair accumulating on the floors.

  • Nail Care

Trimming your pets’ nails is not only beneficial for their comfort but also prevents scratches on your wood floors. Long nails can leave unsightly marks and cause significant damage over time. Regular nail trimming or using protective nail caps can mitigate this risk.

  • Paw Wiping

Implementing a paw wiping routine is an excellent practice to prevent dirt and moisture from being tracked onto your wood floors. Place a doormat or use pet-friendly wipes near entryways to clean your pets’ paws before they enter the house.

  • Protective Floor Coverings

In high-traffic areas or during periods when your pets are more active indoors, consider using protective floor coverings such as area rugs or runners. These coverings provide an additional layer of defense against accidental spills and scratches.

  • Cleaning Spills Immediately

Accidents happen, and when they do, it’s essential to act quickly. If your pet spills water or any other liquid on the wood floors, promptly clean it up to prevent staining or warping. Use a soft cloth or paper towel to absorb the liquid and follow up with gentle cleaning to remove any residue.

  • Regular Cleaning and Maintenance

To keep your wood floors looking their best, establish a regular cleaning routine. Use a broom, vacuum, or dust mop to remove dirt, dust, and pet hair regularly. Additionally, consider using a wood-safe cleaner recommended by the flooring manufacturer to maintain the floors’ shine and integrity.

Refinishing Hardwood Floors with Pet Stains

If you catch pet stains quickly, there are a few methods you can try:

  • Enzymatic cleaner: Non-toxic enzyme cleaners are effective at removing pet odors from both hardwood and carpet. However, this method only works if the stains are caught early.
  • Hydrogen peroxide: Soaking pet stains with hydrogen peroxide and scrubbing the area with peroxide-soaked rags or cloths may prove successful. Afterward, cover the area with baking soda and vacuum it up after an hour. This process can also help bleach deeper stains, but the results may vary.
  • White vinegar and grapefruit oil: Mix one cup of vinegar with warm water and add a few drops of grapefruit oil to create a natural disinfectant. Apply this solution to lesser stains, then cover the area with baking soda and vacuum it up after an hour.

If none of these measures work, it indicates that the urine has likely permeated the hardwood for an extended period. In such cases, more extensive measures are required.

Eliminating Pet Stains Soaked Through Hardwood Floors

While it is possible to eliminate pet stains from hardwood floors that have penetrated deeply, be prepared for an intensive and extensive process. In all likelihood, refinishing the entire hardwood floor will be necessary.

Contrary to a popular myth, sanding alone cannot remove pet stains. Once the urine has transformed into ammonia, it penetrates the wood extensively, causing the hardwood to darken. Additionally, staining the affected area poses challenges, as some wood species do not take stain well or at all. Even if the wood can be stained, the color difference between the patched area and the rest of the floor will be noticeable.

Regrettably, hardwood floors with pet stains that have deeply penetrated the material must be removed, and the floor must undergo a complete refinishing.

Procedure for Removing Stained Hardwood Pieces and Refinishing the Floor

To effectively address pet stains that have deeply soaked into hardwood floors, follow these steps:

  • Remove the affected boards: Pull up the stained boards and replace them.
  • Refinish the floor: Clean the floor, sand it, apply stain, finish the surface, and clean it once again. This process is meticulous and challenging.

Fortunately, professional floor refinishing may not be as costly as anticipated. Flooring professionals have honed their skills and techniques, allowing them to complete the work faster and more effectively than if you were to attempt it yourself.

Opting for a dark stain to cover up pet stains is a tempting solution for some homeowners. While it may be feasible for certain hardwood floors with pet stains, there are potential drawbacks to consider. First, not all wood species respond well to staining, limiting the effectiveness of this approach. Additionally, a dark-stained floor may not complement the overall design of the room. It’s important to note that staining still requires sanding, and the level of labor involved is often so close to full refinishing that it makes more sense to proceed with the comprehensive refinishing process.


Dealing with pet stains on hardwood floors can prove to be a challenging endeavor. Once pet stains have permeated the wood and turned into ammonia, it becomes nearly impossible to remove them without replacing the affected boards and refinishing the entire floor. Seeking the expertise of professional flooring services can simplify the process and ensure a satisfactory outcome.

Remember, it’s essential to act swiftly when addressing pet stains to minimize the extent of the damage and increase the chances of successful restoration. Regular maintenance, such as cleaning the floors, trimming your pet’s nails, and promptly attending to urine accidents, can help prevent or minimize the occurrence of pet stains. By taking proactive measures and seeking professional assistance when needed, you can maintain the beauty and longevity of your hardwood floors.
