Cat urine odor can be stubborn and unpleasant, especially in the basement, where it can linger indefinitely due to the damp, stagnant air. While getting your basement to smell fresh can be challenging, it’s not impossible. Keep reading for an easy-to-follow guide filled with tips and tricks that will help eliminate bad urine smells once and for all.

Before You Begin

It’s important to gather your supplies so you won’t need to stop once you get started. You might already have most of the items that you need, but they’re all relatively easy to find and inexpensive.

How to Get Rid of Cat Urine Smells in a Basement

1. Identify the Source

The first step in eliminating cat urine smells in your basement is to locate the source of the odor. Cats may urinate in various areas, including corners, behind furniture, or on carpets. Inspect your basement thoroughly, using your nose to pinpoint the strongest odor. To detect hidden urine stains, consider using a black light. Cat urine will fluoresce under ultraviolet light, making it easier to identify affected areas. It will also help ensure that you get the area completely clean.

2. Blot and Remove Excess Urine

Once you have identified the urine stains using your nose and a black light, wear protective gloves, and use paper towels to blot up as much urine as possible if you find any puddles on hard surfaces.

3. Mix the Cleaning Solution

If the urine is on a hard surface, you can use a cleaning agent to remove it. Many different brands are available, but we recommend an enzyme-based cleaner because it works by destroying the organic material that is creating the odor, so it’s gone forever. Mix the cleaner that you choose with warm water according to the directions on the package.

If you're trying to find an enzyme cleaner that does it all, we highly recommend our favorite cleaner, the Hepper Advanced Bio-Enzyme Pet Stain & Odor Eliminator Spray.

4. Scrub the Area

Scrub the affected area thoroughly using a scrub brush or a durable sponge. You typically let the solution set for a short time so the enzymes can do their work.

5. Rinse the Area

Rinse the area with clean water, and dry it with a towel or paper towel.

6. Blot and Absorb Excess Urine

If the urine is on a porous surface, like a carpet, you may be able to blot the area with a paper towel to soak up the urine.

7. Apply Cleaning Solution

Apply your enzyme cleaner, following the instructions for porous surfaces on the container. Allow it to soak for the recommended time to destroy the organic material creating the bad odor.

8. Rinse and Extract

After soaking, rinse the area with clean water, and use a wet vacuum or extractor to remove excess moisture and cleaning solution to get it as dry as possible.

9. Dry and Deodorize

Allow plenty of time for the area to dry completely, whether you are working on a hard or porous surface. Then, apply a pet-safe odor neutralizer to help freshen up the area. Many brands are available, so take time to find something that you like.

10. Repeat If Necessary

Stubborn odors may require multiple cleaning sessions. Be patient and persistent and repeat the previous steps until you have successfully eliminated the urine smell.
