How to Clean Cat Pee from Carpet? - Carpet Cleaner Reviews

If you’re a cat owner, chances are you’ve faced the dreaded moment of discovering a urine stain on your carpet. Whether it’s from a stressed pet, a litter box mishap, or an unexpected health issue, cat pee isn’t just unpleasant—it’s notoriously difficult to remove. The odor can linger, and if not cleaned properly, it may even encourage repeat accidents in the same spot. In this guide, we’ll walk you through exactly how to clean cat urine from carpet, step by step.

What You’ll Need

Before you begin cleaning, it’s important to gather the right tools and supplies. Cat urine is potent and can seep deep into carpet fibers, so using the proper products makes a big difference in removing both the stain and the odor.

Paper Towels or Clean Cloths

You’ll need something absorbent to blot the urine. Paper towels are convenient and disposable, but a clean cloth or microfiber towel also works well. Avoid anything too abrasive—you don’t want to rub the urine in or damage your carpet.

White Vinegar

White vinegar is a natural deodorizer and helps neutralize the ammonia in cat urine. It’s also safe for most carpets. You’ll mix it with water to create a solution that helps lift the stain and reduce the smell. Just be sure to do a spot test first in an inconspicuous area to make sure your carpet’s dye doesn’t react.

Baking Soda

Baking soda is another powerful natural odor remover. After applying the vinegar solution, sprinkling baking soda over the area helps absorb lingering moisture and smells. It also breaks down urine acids during the drying process, making it easier to vacuum up later.

Enzyme-Based Cleaner (Pet-Specific)

This is one of the most important items on the list. Enzyme cleaners are specifically designed to break down the uric acid and bacteria in pet urine. Unlike regular household cleaners, enzyme-based solutions actually digest the source of the odor, preventing your cat from returning to the same spot. Look for a product labeled for pet urine, and follow the instructions carefully.

Spray Bottle

If you’re mixing your own cleaning solution (like vinegar and water), a spray bottle is the easiest way to apply it evenly to the carpet. It gives you control over how much solution you use and helps prevent oversaturation.

Vacuum Cleaner

Once everything has dried, a vacuum cleaner will help you remove the dried baking soda and any loosened debris. A regular vacuum works fine, but if you have a carpet shampooer or wet vac, those can be especially helpful for deeper cleaning.

Optional: Blacklight

If you’re dealing with a mysterious lingering smell but can’t find the source, a blacklight can reveal old or hidden urine stains. Just turn off the lights and scan the area—urine will glow under UV light, making it easier to target problem spots.

Step-by-Step: Fresh Cat Urine on Carpet

Dealing with a fresh cat urine accident can feel stressful, but acting quickly makes all the difference. The faster you respond, the better your chances of removing the stain and odor completely.

Step 1: Blot Immediately—Don’t Rub

As soon as you notice the spot, grab paper towels or a clean cloth and gently blot the area. Press firmly to absorb as much urine as possible. If the urine has soaked through, you may need to layer towels and step on them lightly to pull up more liquid. The key here is blotting—rubbing can push the urine deeper into the carpet fibers and padding, making the smell harder to remove.

Step 2: Apply a Vinegar and Water Solution

Once you’ve absorbed most of the urine, mix a solution of equal parts white vinegar and water (1:1 ratio) and pour or spray it directly onto the affected area. This helps neutralize the ammonia in cat urine and also starts to lift any potential staining.

Let the solution soak into the carpet for a few minutes. This allows it to reach the same depth the urine did, so you’re treating not just the surface but also the underlying fibers.

Step 3: Blot Again to Remove Excess Moisture

After allowing the vinegar solution to sit, use fresh paper towels or cloths to blot up as much liquid as possible. Just like in step one, press down firmly rather than rubbing. You want to extract all the moisture you can before moving on to the next step.

Step 4: Sprinkle Baking Soda Over the Area

While the carpet is still damp from the vinegar solution, sprinkle a generous amount of baking soda directly over the affected area. The baking soda will help absorb remaining moisture and neutralize any lingering odor. You may hear some fizzing or bubbling as it reacts with the vinegar—this is completely normal and part of the deodorizing process.

Let the baking soda sit for several hours, or ideally overnight, so it has time to do its job. Make sure the area stays undisturbed during this time.

Step 5: Vacuum Thoroughly

Once the baking soda has dried completely, vacuum the area thoroughly to remove all the powder. You may need to go over it a few times to get everything out, especially if your carpet has a deep pile.

After vacuuming, the area should smell fresh and clean. If there’s still a slight odor or discoloration, you can repeat the vinegar and baking soda process once more or move on to using an enzyme cleaner for added strength.

Deep Cleaning Old or Dried Stains

Old or dried cat urine stains are trickier to remove because the urine has had time to soak deep into the carpet fibers—and possibly into the padding or subfloor. These stains often leave behind a strong, persistent smell and may not be visible to the eye. But with the right approach, you can still eliminate them effectively.

Locate the Stain

If you’re unsure where the smell is coming from, use your nose or consider using a blacklight. Cat urine will glow under UV light, making it easier to pinpoint hidden or dried spots. Mark the affected areas with a piece of tape or chalk so you can treat them thoroughly.

Saturate with Enzyme Cleaner

Enzyme cleaners are your best tool for old stains. These cleaners contain live bacteria that break down the uric acid crystals in cat urine—something soap and vinegar can’t fully do. Generously apply the enzyme cleaner to the entire stained area, making sure to soak it deeply. If the stain has penetrated the padding, you may need to use enough product to reach those lower layers.

Read the product instructions carefully—most recommend letting the cleaner sit for at least 10 to 15 minutes, but deeper stains may benefit from a longer dwell time. Some products even suggest covering the area with a damp cloth to keep the enzymes active while they work.

Blot and Let Air Dry

After the cleaner has had time to soak, blot up any excess moisture using paper towels or a cloth. Avoid rinsing at this stage—the remaining enzymes will continue to work as the area dries. Let the spot air dry completely, which can take anywhere from a few hours to a full day, depending on how much solution was used.

It’s best to keep pets and foot traffic away during this drying phase to prevent re-soiling and interference with the cleaning process.

Repeat if Necessary

Stubborn or older stains may need more than one round of treatment. If you still detect an odor after the first application, repeat the process: reapply the enzyme cleaner, let it sit, blot, and allow to dry again. Patience is key—deep urine stains often require a few rounds to fully break down all odor-causing residues.

Optional: Rinse and Vacuum

Once the stain has fully dried and the smell is gone, you can do a final rinse with plain water and blot to remove any residue left by the enzyme cleaner. After it dries again, vacuum the area to fluff the carpet and restore its texture.

Avoiding Common Mistakes

Cleaning up cat urine can be frustrating, especially if you’re not getting the results you hoped for. Many people make common errors that actually make the problem worse. Knowing what to avoid can save you time, money, and additional stress.

Don’t Use a Steam Cleaner

It might seem like a good idea to use a steam cleaner on urine stains—after all, heat lifts dirt, right? Unfortunately, this method can actually lock in the odor. The heat from steam cleaners can bond the proteins in cat urine to the carpet fibers, making the smell even more difficult to remove. Avoid steam cleaning until the urine has been properly treated and neutralized with an enzyme cleaner.

Avoid Ammonia-Based Products

Ammonia smells very similar to cat urine. If you use an ammonia-based cleaner, your cat might interpret it as another animal’s urine and feel the need to mark the area again. Additionally, ammonia doesn’t break down uric acid, so it won’t be effective for deep odor removal. Always opt for enzymatic cleaners or vinegar-based solutions instead.

Don’t Scrub Aggressively

Vigorously scrubbing at a urine stain might feel satisfying, but it can actually damage your carpet. Scrubbing pushes the urine deeper into the carpet pad and spreads it out over a wider area. It can also fray carpet fibers and cause permanent wear. Instead, always use a blotting motion and work gently to lift moisture without spreading the stain.

Don’t Skip the Enzyme Cleaner

Vinegar and baking soda can help with light odors, but they don’t completely eliminate the uric acid crystals left behind by cat urine. These crystals are what cause the lingering odor and attract your cat back to the same spot. Skipping the enzyme cleaner often results in temporary relief followed by recurring smells. For long-term success, especially with older or deeper stains, enzyme treatment is essential.

Don’t Assume One Cleaning is Enough

It’s easy to get discouraged if the smell doesn’t go away after one cleaning, but that doesn’t necessarily mean you did it wrong. Sometimes, deep or old urine stains require repeated treatments. Be patient and persistent—urine can be stubborn, but with consistent care, you can completely eliminate the issue over time.
