Removing Old Dog Urine Stains out of Carpet

Some carpet stains can be easy to forget, but pet urine stains are hard to ignore. Whether they’re fresh or have been there for months, pet urine stains can be really tough to get rid of. They make your carpet look bad and your room smells unpleasant unless you deal with them. Until you do, it’s not a good idea to have guests over in that part of the house.

Cleaning up cat and dog pee urine stains is not easy, especially if you let them sit and dry. Using deodorizers might help a bit, but the urine smell will usually come back. In this guide, I’ll explain the best ways to permanently solve this problem and remove old urine stains from your carpet

How can you tell if a urine stain on your carpet is old or fresh?

When it’s fresh, it’s usually easy to see because it looks wet and dark. But when it dries up and blends in with the carpet, it’s harder to find. Even though you can smell it, finding the exact spot can be tricky without the right tools.

One good tool to use is a UV flashlight. Instead of sniffing around on your hands and knees, you can invest a little bit of money in a UV flashlight like the Escolie UV flashlight. It can help you find old urine stains because they contain phosphorus, which glows yellowish when you shine UV light on them.

Moisture Meters

Moisture meters are tools that can help you find urine stains accurately. These meters work well because uric acid crystals in the urine keep attracting moisture, and even if the stain has dried up, there’s still a bit of dampness that these meters can detect. This leftover dampness can cause a lingering dog or cat smell, even months after the accident happened.

Moisture meters are good at finding urine stains in places where blacklights might not work, and they won’t give you false results from other marks, like bodily fluids that might glow under UV light. The only problem with moisture meters is that they can be expensive. Professional ones can cost a few hundred dollars, which might not be practical for homeowners who only deal with occasional pet accidents. You could try using a standard wood moisture meter, but it might not be as reliable for finding old stains.

How to Get Rid of Urine Stains on Carpet Using Enzyme Cleaners

  1. Spray the enzyme cleaner generously over the urine stain. Make sure to cover not just the stain itself but also the area around it to ensure it reaches all the urine that might be underneath.
  2. Let the cleaner sit on the stain for a while. If the stain is really bad, you might need to leave it for up to 8 hours.
  3. Use clean towels or paper towels to soak up any liquid that’s left. Put something heavy on top of them to help absorb any moisture deep in the carpet.
  4. After you’ve soaked up all the liquid, rinse the area with plain tap water and a damp cloth to get rid of any leftover residue from the cleaner.
  5. Keep using towels or a wet/dry vacuum to get rid of any remaining water until the area is completely dry.

Note: Enzyme cleaners are great for getting rid of the smell of pet urine, but they might not completely remove the stain. To make the stain disappear, I suggest using a carpet spotter like the Bissell Little Green portable carpet cleaner with a good pet stain remover. Another option is a carpet cleaning spray like Resolve Carpet & Rug, which can help get rid of any remaining stain and make your carpet look new.

How to Get Rid of Old Pet Urine Stains

How to Remove Dog Pee and Other Stains from Carpet

I recommend using an enzyme cleaner for old pet urine stains that have dried into the carpet. These cleaners contain live bacteria and enzymes that help break down the smelly stuff in urine and turn it into water and CO2, which can evaporate harmlessly. Some popular products to try are:

Most of these products suggest leaving them on the stain for 5 to 60 minutes, but if the stain is really bad, you can leave them on for a few hours. If you don’t treat the stain, it can soak through the carpet and even into the padding and subfloor. Sometimes, the urine has spread wider under the carpet than you can see on the surface, so keep that in mind when you’re using the cleaner.

How to Use Hydrogen Peroxide to Clean Urine Stains on Carpet

Hydrogen peroxide is a great DIY solution for getting rid of tough stains like red wine spills or deep yellow urine stains. It’s often better than enzyme cleaners at making your carpet look good again. Hydrogen peroxide works by lightening the color of the stain as it reacts with the staining stuff. Adding baking soda and dish soap makes it even better at getting rid of dirt and odors. Here’s how to use it as a spray to remove urine stains:

  1. Put one cup of hydrogen peroxide into a spray bottle. Add a couple of drops of dish liquid and 2–3 tablespoons of baking soda.
  2. Mix it well until the baking soda disappears.
  3. Try a small test spot in a hidden area of the carpet and let it dry to make sure it doesn’t leave any marks.
  4. Shake the spray bottle and generously spray the stain, making sure to go a bit beyond the edges of the stain.
  5. Gently scrub the solution into the carpet and let it sit for 20–60 minutes.
  6. Use a damp cloth to rinse the area and get rid of any leftover cleaning stuff.
  7. Blot the area dry with paper towels or use a wet/dry vacuum to remove any extra moisture.

Note: If your regular 3% hydrogen peroxide isn’t doing the job, you can try a stronger 20-volume clear developer to speed up the pet odor stain-removal process. Be sure to test it in a hidden spot first to avoid damage and figure out the right timing and technique.

How to Clean Up a Fresh Urine Stain

If you catch the urine stain while it’s still wet, that’s good news. Your first step should be to gently blot the area with a clean cloth or paper towel to soak up as much urine as possible. If you have a wet/dry vacuum, that can be really helpful too.

Before you use a cleaning solution, you can flush the stain with cold water and use the vacuum to suck up the liquid, which helps remove even more urine from the carpet.

Once the spot is dry you can try one of these methods to clean up the urine and stop it from leaving a stubborn stain.

How to Effectively Use Pet Stain and Odor Remover

My Suggestion: Vinegar and Baking Soda to Clean Fresh Urine Stains

Vinegar and baking soda can work well together to clean up fresh pet urine stains. Here’s what you can do:

  1. Mix equal parts of distilled white vinegar and warm water in a spray bottle.
  2. Shake the bottle to mix the solution and then spray it generously on the urine stain.
  3. Gently scrub the solution into the spot.
  4. Use a clean cloth to blot up as much moisture as you can.
  5. Sprinkle a good amount of baking soda over the stain to soak up any remaining urine or cleaning solution. Leave it for a few hours.
  6. Once it’s dry, vacuum up the baking soda.

Note: Vinegar is good for getting rid of odors and cleaning fresh urine stains, but it may not completely get rid of all the compounds in the urine that cause the smell. If you still notice an odor a few days after using vinegar, it’s a good idea to switch to an enzyme cleaner for better results.

Using Soap and Water to Clean Fresh Urine Stains

Soap and water are a great choice for getting rid of a fresh urine stain quickly. Here’s what you can do:

  1. Mix just a tiny bit of dishwashing liquid (like 1-2 drops) with warm water in a bowl.
  2. Take a clean cloth or sponge and dip it in the soapy water. Then, gently blot the stain.
  3. Use another cloth dipped in warm water to rinse away the soap from the spot.
  4. Get rid of any leftover dishwashing liquid by blotting it with a clean cloth.
  5. Keep blotting the area with dry towels until you’ve soaked up all the moisture.

Tip! Two important things to remember: Use only a small amount of soap, and if you can, use a wet/dry vacuum to dry the area. It’s really important to get rid of all the soap because if any is left, it can attract dirt and make the stain worse. Using too much soap means you’ll have to rinse a lot and risk making your carpet too wet. A wet/dry vacuum is great for removing moisture without spreading it around.

Why Urine Stains Are a Concern

It’s important to act fast when you have urine stains on your carpet. If you don’t, it can lead to tough stains and a lingering bad smell. As time goes on, the urine goes deeper into the carpet and even soaks into the padding underneath. It can even reach the subfloor, which is a big problem. The longer you wait, the harder it is to fix the damage and get rid of the urine.

Can Urine Stains on Carpets Be Permanent?

Sometimes, urine can permanently change the color of carpet fibers. How bad it gets depends on what’s in the urine and the type of carpet you have. Carpets made from synthetic materials and those with stain-resistant coatings are easier to clean.

But no matter the carpet, the smell of urine is always a problem. When urine breaks down, it releases smelly compounds that make pet urine stink. The urine crystals in the carpet keep drawing in moisture and stay active, causing the odor to come back even years later, especially when it’s humid.

The longer the urine stays in the carpet, the harder it is to completely remove it with stain and odor removers. And if you can’t get rid of the smell, your pet might keep having accidents in the same spot.

The Health Effects of Urine Stains

Getting rid of the smell from urine stains is really important, and not just for comfort. Even though it usually takes a lot of urine to be a health concern, the germs and the strong ammonia smell it creates can irritate your face and make it harder to breathe. Kids and people with weaker immune systems are more at risk of having problems. If the moisture from the urine in the carpet leads to mold, that’s another thing that can affect the air quality in your home and make it harder for everyone to breathe.

How to Stop Urine Stains Before They Happen

It’s much easier to prevent pet urine stains than to clean them up later. For most pet owners, the key is proper training. If your pet has always had accidents, you might need to start fresh with a litter box or crate training.

If your pet starts peeing inside suddenly, it’s a good idea to talk to your vet. Sometimes, health problems like urinary tract infections can make pets pee in the wrong places. Changes in their daily routine or environment can also stress them out and lead to accidents.

Age can be a factor too. Young cats might spray around the house, and older pets might have trouble getting to the right spot to pee. Your vet can help figure out what’s causing the issue and how to fix it.

While you’re working on the peeing problem, you can protect your carpet with a repellent spray. It won’t guarantee any accidents, but products like Soft Clad Extra Strength Fabric Protector can make it harder for moisture to soak into your rugs and furniture. Use it after cleaning, and if there are future stains, they’ll be on the surface and easier to clean up.


Stop Your Pet from Peeing in the Same Place

If your dog or cat keeps peeing in one spot, it’s probably because they can still smell their previous pee there. To solve this, you need to clean the area really well with an enzyme cleaner to get rid of all the odor. This can be tough, especially on old stains. Even if we can’t smell it anymore, pets can still detect the faintest trace of the smell.

While you’re working on cleaning, you might also need to block off the spot to keep your pet away. You can use things like a baby gate or put a mat or piece of furniture over the area. Another trick is to change the meaning of that spot for your pet. Instead of letting them pee there, use it for play or feeding. This can help them forget their old habit of peeing there.


Removing old dog urine stains from your carpet requires patience and the right approach. By following the steps outlined in this guide, you can effectively tackle even the most stubborn stains. Remember to act quickly, use the right cleaning solutions, and consider a professional Carpet cleaner henderson nv help if needed. With our expert advice, your carpet can be clean, fresh, and free of urine stains once again.
