Common Sources of Urine Smell Out of Carpet


Yes, accidents happen—toddlers are prime suspects. And while we love our little ones, their accidents can make your living room smell less like home and more like a highway rest stop.


Man’s best friend has its moments. Even the most well-trained pooch can slip up, especially when young, old, or under the weather.


Cats are often meticulous, but when they go outside the litter box, it’s usually a sign to pay attention. It could be a protest or a health issue, so keep an eye out!

Addressing New Urine Stains

Upon discovering a urine stain, start by taking a handful of tissues and placing them over the spot until you’ve formed a thick layer. You can further cover this with newspaper or an old cloth that you don’t mind using for this purpose. It’s essential to wear gloves throughout the cleaning process and thoroughly wash your hands afterward.

The goal is to allow the tissues to absorb the urine before it seeps into the carpet fibers. For better absorption, you can place a weight on top of the tissues to increase their effectiveness in soaking up the urine. If the stain is significant, consider replacing the used tissues with a fresh layer to continue absorbing the urine.

Once the urine has been absorbed, remove the tissues and rinse the affected area with water. Using a wet vacuum can significantly expedite and simplify this process, ensuring thorough cleaning and removal of any remaining residue.

Getting Rid of New Pee or Urine Odour

Baking Soda

This pantry staple is like the Swiss Army knife of home care. For fresh pee spots, sprinkle a generous amount of baking soda directly on the wet area. Let it sit overnight, then vacuum it up. Baking soda absorbs both moisture and odours, giving you a double bang for your buck.

White Vinegar and Water

Mix equal parts of white vinegar and water in a spray bottle. Spray liberally on the urine spot and let it sit for 10-15 minutes. Blot with a clean towel. Vinegar’s acidity breaks down urine residue and neutralises the smell.

Addressing Old Urine Stains or Spots

Addressing old urine or pee stain requires a bit more detective work and elbow grease, but it’s not impossible to reclaim your carpet. Here’s a detailed guide on revamping your approach to tackle these stubborn invaders.

The Pre-Treatment

Before you even start with solutions and scrubbing, vacuum the affected area thoroughly. This removes any loose debris and prepares the carpet fibres to better absorb the cleaning solutions you’ll apply. A clean slate increases the efficacy of your treatments.

Custom Solution Mix

For old stains that have set, you might need a stronger concoction. Mix one part hydrogen peroxide with one part water and add a teaspoon of baking soda. This mixture adds a powerful punch but test it on an inconspicuous area of your carpet first to ensure it doesn’t bleach the fabric. Apply it to the stain and let it sit for an hour before blotting dry.

The Agitation Game

Old pee stain often require physical agitation. Use a soft-bristled brush to gently work your chosen cleaner into the fibers. This action helps the solution penetrate deeper and loosens the particles of dried urine. Be gentle to avoid damaging the carpet.

Rinse and Repeat

After treating the pee stain, rinse the area with cold water and blot it with a clean towel or paper towels to remove any residue of the cleaning solution. Sometimes, it might take a few cycles of treatment and rinsing to fully remove the stain and odour.

Sealing the Deal

Once the area is clean and odour-free, applying a carpet protector can help repel future stains. These products create a barrier on the fibers, making it harder for spills and accidents to penetrate and set.

Odour Neutralisers

Finally, consider using a commercial or homemade odour neutraliser. A simple yet effective solution can be made by mixing essential oils like lavender or eucalyptus with water. Spray this lightly over the cleaned area to leave your room smelling fresh.

By integrating these advanced steps into your cleaning routine, tackling old urine stains becomes less daunting. Patience and persistence are key—don’t rush the process. Allow each treatment to do its work, and you’ll see results that not only look good but smell fresh too.

Finding Dried Urine Stains

Sometimes the nose knows before the eyes do. If you can smell but can’t see it, turn off the lights and use a UV flashlight. Dried urine stains will glow, marking the spot for your cleaning crusade.

Cleaning the Carpet

Mix one part water with one part vinegar and add a squirt of dish soap. Apply this solution to the stain and let it work its magic for about 30 minutes. Blot the area dry with a clean cloth, rinse with cold water, and blot again.

Removing Urine Smell Out of the Carpet

For stubborn odours, after the vinegar treatment, sprinkle more baking soda over the area and let it sit overnight again. Vacuum it up the next day. This one-two punch of vinegar and baking soda is a dynamic duo in odour elimination.

How to Get Rid of Tough Urine Stains and Smell

If the above methods feel like bringing a knife to a gunfight, consider renting a carpet cleaner or using a commercial enzymatic cleaner. These cleaners break down the proteins in urine, eliminating the smell at its source.

Enhancing Your Approach

Sometimes, urine stains might seep deeper than the surface, getting cosy with the carpet pad or even the subfloor. In such cases, surface cleaning isn’t enough. You need to go deeper. Here’s how you tackle those villains hiding beneath:

Deep Cleaning for Stubborn Stains

For urine that’s made its way into the carpet padding, a steam cleaner can be your best ally. Steam cleaners use hot water extraction to pull out deep-seated dirt and odours. Be careful, though; over-wetting can lead to mould. Always follow the manufacturer’s instructions and ensure adequate ventilation for drying.

Enzymatic Attack

When the usual cleaning suspects fail, it’s time to call in the special forces: enzymatic cleaners. These are specifically designed to tackle organic stains like urine by breaking down the odour-causing elements. Apply the enzymatic cleaner according to the product directions, usually letting it sit for a few hours to thoroughly munch away at the urine compounds.

Preventive Measures

Once your carpet is clean, focus on prevention. If pets are the culprits, reinforce training or introduce more frequent bathroom breaks. For little humans, encourage regular bathroom visits and keep a watchful eye during potty training.

The Science Behind the Smell

Urine not only smells bad but can also be a breeding ground for bacteria, which can contribute to a lingering odour. Understanding this can help tailor your cleaning process. Bacteria thrive in moist environments, so drying the area quickly after cleaning is crucial. Fans or open windows can accelerate the drying process.

Adjusting Your Home’s Environment

Maintaining low humidity in your home can prevent the recurrence of odours. Humidity can rehydrate dried urine, reactivating the smell. Use dehumidifiers in damp areas and consider air purifiers to keep the air fresh.

When to Call Professionals

If DIY methods are overwhelmed, it’s not a defeat to call in professional carpet cleaners. They have industrial-grade equipment and solutions that can eradicate odors that home methods cannot. This can be particularly crucial if you’re dealing with allergens or if the urine has contributed to mould growth.

DIY vs. Professional: Why Choose Professionals

Deciding whether to tackle urine stains yourself or call in the professionals can be a toss-up. Let’s weigh the pros and cons to see why sometimes, calling in the experts might be your best bet.

Expertise and Efficiency

Professional cleaners bring a level of expertise and efficiency that DIY methods can struggle to match. They have the training and equipment to diagnose and treat carpet issues quickly and effectively. This is especially crucial with older, set-in stains where the wrong approach can worsen the situation.

Advanced Equipment

Professionals use high-grade equipment that can extract dirt and liquids deep from within the carpet fibres—far beyond what most consumer-grade cleaners can achieve. This deep cleaning not only removes stains and odours more effectively but also extends the life of your carpet.


Let’s face it: your time is valuable. Carpet cleaning can be labour-intensive, especially with stubborn stains. Hiring professionals frees you up to focus on other tasks or simply relax, knowing the job will be done right.

Guaranteed Results

Many professional cleaning services offer guarantees. If the stain resurfaces, they’ll often come back to address it at no additional charge. This peace of mind is something DIY solutions rarely provide.

While DIY carpet cleaning can be effective for minor issues, when it comes to deep, stubborn stains and pervasive odours, professional services offer a level of thoroughness, expertise, and convenience that DIY methods can’t always match. Knowing when to call in the professionals can save you not only time but also ensure that your home remains a clean and pleasant environment.


With patience and the right tools, even the most stubborn urine smells can be defeated, leaving your carpet fresh and inviting. Remember, tackling the stain promptly will always give you a fighting chance against lingering odours.
