How to Remove Smell of Cat Urine From Concrete

Cat urine can leave a strong and unpleasant odor on concrete surfaces. Whether it’s your garage, basement, or patio, getting rid of the smell can be quite a challenge. However, with the right approach and products, you can successfully eliminate the odor and restore freshness to your concrete surfaces. Here’s a step-by-step guide on how to remove the smell of cat urine from concrete.

1. Start by removing any excess urine on the surface with paper towels or a cloth. Dispose of it properly to prevent further odor.

2. Mix a solution of one part vinegar and two parts water. Vinegar is known for its strong odor-fighting properties and can neutralize the ammonia smell in cat urine.

3. Apply the vinegar solution to the affected area, ensuring full coverage. Let it sit for about 15-20 minutes to allow the vinegar to penetrate and break down the odor-causing compounds.

4. Scrub the area with a stiff-bristled brush to loosen any remaining urine residue. For stubborn stains or odors, consider using a pet-specific enzymatic cleaner. These cleaners contain enzymes that break down the urine at a molecular level, effectively eliminating the smell.

5. Rinse the area thoroughly with clean water to remove any traces of the vinegar or enzymatic cleaner. Use a wet vacuum or mop to remove the excess moisture.

6. If the odor persists, repeat the process or consider using a cat urine odor neutralizer. These products are specifically designed to eliminate the smell of cat urine and can be found at most pet stores.

7. Finally, ensure proper ventilation in the area to allow fresh air to circulate and aid in odor removal.


1. Can I use bleach to remove the smell of cat urine from concrete?
No, bleach can actually amplify the odor rather than eliminate it. It contains ammonia, which is also present in cat urine, and can create a more pungent smell.

2. Will steam cleaning remove the cat urine smell?
Steam cleaning can be effective in removing the smell of cat urine from concrete. However, it may not penetrate deep enough to completely eliminate the odor.

3. Is it necessary to use an enzymatic cleaner?
While vinegar can help neutralize the smell, an enzymatic cleaner is more effective in breaking down the compounds that cause the odor. It’s recommended for stubborn stains and strong smells.

4. How long does it take for the smell to disappear?
The time it takes for the smell to completely disappear depends on the severity of the odor and the effectiveness of the cleaning method. It may take a few days or even weeks for the smell to completely dissipate.

5. Can I use the same method for other concrete surfaces, like outdoor patios?
Yes, the same method can be applied to all concrete surfaces, including outdoor patios. However, it’s important to consider weather conditions and ensure proper ventilation during the cleaning process.

6. Are there any preventive measures to avoid cat urine odor on concrete?
Providing a clean litter box and regular cleaning can help prevent cats from urinating on concrete surfaces. Additionally, ensuring your cat is well-hydrated may reduce the concentration of urine, minimizing the odor.

By following these steps and taking the necessary precautions, you can successfully remove the smell of cat urine from concrete and restore freshness to your living space.
