How to Remove Odours from a Couch Permanently

Numerous factors could contribute to the couch having an unpleasant smell. This includes pets having an accident, spilled food, smoke, sweat, body oils, moisture, mould build-up, and regular wear and tear. Often, the odour will persist despite attempts to clean the surface by vacuuming or spraying fabric refresher, as the cause of the smell actually exists deep inside the furniture.



To permanently eliminate odours on a couch, you should not just mask the smell with another smell. The cause of the odour needs to be located, treated, and removed as thoroughly as possible. Minor odours might be treatable with home methods, while persistent odours related to pets, urine, smoke, or mustiness need a professional upholstery cleaner.


At Railway City Carpet Cleaning, we assist our customers from London, St. Thomas, and surrounding areas with cleaning their upholstered furniture.


Why Does a Couch Develop Unpleasant Odours?


It may be difficult for many homeowners to understand how much a sofa can absorb. It is a place where people, children, pets, and even visitors rest every day. As a result, the fabric accumulates all sorts of dead skin cells, sweat, crumbs, pet fur, hair, dust, oil, and even particles that float in the air. The material gets deeper into the sofa over time.

A smell starts to appear when organic material meets bacteria or moisture. For instance, even if a small amount of liquid falls on the sofa, it might be absorbed. Animal urine could go through the fabric and penetrate into the padding. Smoke particles could settle everywhere on the sofa. When the substance gets to the core of the sofa, it starts smelling under certain conditions of temperature and humidity.


Identify the Source Before Cleaning


First, find out where the smell comes from before removing it. Smell the seats, arms, back, stitching, and areas behind movable seats. See if the smell is localized to a certain part of the furniture or if it’s widespread.


The localized smell may be caused by some stain, spill, accident of the pet, or wetness. The overall stale smell may be the result of body oils, dust, cigarette smoke, or normal usage of the sofa.


It is important to identify the source because odors should be treated differently. The technique that works for removing food smells may not be efficient for pets, cigarettes, or moisture.


Check the Upholstery Cleaning Code

Prior to using water or any other cleaner, always look for the care tag attached to the upholstery. This may carry a cleaning code that will give you information on what cleaning procedure should be used.


Some common cleaning codes are:


  • W: It suggests the use of water-based cleaner.

  • S: Solvent-based cleaners can be used.

  • W/S: It suggests either solvent-based or water-based cleaner.

  • X: Cleaning by vacuuming or professional cleaning only.


If you ignore the cleaning code, there is a possibility of color fading, shrinkage, water stains, texture change or even damage to the material.


Vacuum the Couch Thoroughly


The most reliable initial step is vacuuming. You should take out the cushions and use a brush to clean all sides, including the arms, the seating area, the back, the seams and the corners.


It will help you get rid of pet hairs, crumbs, dust, dead skin cells and any other material that can cause foul smells. In addition, it will prevent the dry material from becoming mud in case you add moisture to the couch.


However, vacuuming is not enough for removing the smell since it does not penetrate inside the fabric and the padding.


Can Baking Soda Remove Couch Odours?


It is possible that baking soda might be able to help in absorbing certain light odours. Just spread an even thin coating of baking soda on the dry upholstery, let it sit for a few hours and vacuum it away properly. It might help to get rid of any odour that is created through general usage or from food or pet related problems.

But baking soda cannot extract the odorous materials like urine, oil, smoke particles or bacteria from within the furniture. Also, it may make your furniture smell better, without eliminating the problem. Baking soda can be difficult to remove from some thick materials.


Treat Fresh Spills and Pet Accidents Quickly


For fresh incidents, it is important to act quickly. Soak up the spill carefully using clean and absorbent towels. Do not rub or scrub the surface since this will cause the liquid to soak further into the upholstery fabric.

Keep soaking until almost no liquid soaks through to the cloth. In cases where water is allowed in the cleaning of the furniture according to its instructions, apply minimal amounts of upholstery cleaner. It is not good to allow excess amounts of moisture to soak into the upholstery since the liquid may penetrate the upholstery pad creating an odor problem that lasts.


Odor from pet urine has to be addressed especially since the urine contains organic substances that still produce odors even after cleaning. Enzyme cleaners may help remove such stains, although the right type of enzyme cleaner has to be used properly for the type of fabric used.


Why Fabric Sprays Usually Provide Temporary Results


It is possible to clean a couch temporarily by using fabric fresheners and fragrant sprays.

However, it is necessary to understand that they do not get rid of the material that creates an unpleasant odor; rather, they add scent to the already contaminated fabric.

The moment the fragrance disappears, the initial odor appears again. Moreover, it is possible that the use of fragrances will result in a sticky residue being deposited in the material, which will gather more dirt and dust in the future.


It is only possible to achieve a long-lasting effect if the material is removed from the couch.


How to Remove Pet Urine Odours from a Couch


Pet urine smells are among the hardest sofa smells to eliminate because they permeate through the surface fabric and into the stuffing inside the cushion. At that point, it is out of reach of normal vacuuming and surface sprays.



Should the incident be recent, then soak up as much of the spill as you can without smearing it. Avoid the use of excess water, heat such as that generated by household appliances, or chemicals until you consult the care instructions of your furniture fabric.

A professional furniture cleaner will be able to analyze the extent of penetration of the urine and apply a suitable cleaning solution. In cases where the cushion stuffing is saturated, a lot of cleaning will help reduce the smell but the stuffing needs to be replaced for complete elimination.


How to Deal with Musty Couch Smells


A musty smell usually indicates moisture, limited airflow, or contamination within the fabric or cushioning. Move the couch away from damp walls, inspect for water exposure, and improve ventilation in the room.


Allow the furniture to dry fully before applying any treatment. Continuing to use or cover a damp couch may trap moisture and make the problem worse. If there are visible signs of mould, extensive water damage, or a strong odour that returns after drying, professional inspection is recommended.

Cleaning the surface without correcting the moisture source will not provide a lasting result.


Can Smoke Odours Be Removed from Upholstery?


The particles of smoke can be settled all over the sofa, on its material, cushioning, seams, and the framework inside the sofa. This means that smoke odor is harder to remove compared to a small spill on the sofa.


Cleaning and professional upholstery services can greatly help in getting rid of smoke odor by eliminating the particles of smoke. In some cases, when the sofa has been exposed to cigarette smoke for a long time, several attempts will be needed to clean it up and treat the other surfaces in the house.


How Professional Upholstery Cleaning Removes Deep Odours


Professional upholstery cleaning is better than the surface cleaning as it is intended to lift off and extract the contaminants trapped deep inside the upholstery. Based on the upholstery type, the technician may apply hot water extraction, controlled moisture cleaning, or any suitable fabric-safe method.


Professional upholstery cleaning can help in removing:


  • Body oil residues

  • Food and beverage stains

  • Pet dander and hair

  • Urine stains

  • Dust and soil deposits

  • Organic materials that provide a breeding ground for bacteria

  • Odor particles


The most important aspect of the cleaning process is the powerful extraction as it not only extracts the contaminants but also the moisture trapped deep inside the couch.


Why Choose Railway City Carpet Cleaning?


Railway City Carpet Cleaning begins the process by evaluating the fabric being cleaned and its state, as well as determining the source of any odours. That way, you will have an individual method for each piece of furniture rather than using one and the same method for each and every couch.


We offer professional cleaning services for your upholstery that will enable you to get rid of dirt, stains, body oils, contamination caused by your pets, as well as any odor-producing residues from your sofas, sectionals, loveseats, recliners, and upholstered chairs. We provide our services in London, St. Thomas, and nearby areas.

However, although no reasonable cleaner would be able to promise you complete elimination of all persistent odors, professional treatment always gives you a better chance.


How to Keep Your Couch Smelling Fresh After Cleaning


After cleaning the sofa, some maintenance practices will ensure that there are no bad smells on the sofa. Vacuum it at least once a week, handle stains immediately, and keep your pets and wet things away from the sofa. Remove the coverable part and wash it as per the manufacturer's directions, and use minimal fragranced products. Homes that have pets, children, people who smoke, or that use much furniture should clean the sofa after every 6 to 12 months. Other homes can do it after 12 to 18 months.


Final Thoughts


Odour removal from a couch entails more than masking it with an appealing scent. The actual culprit could range from pet urine to body oils, food debris, smoke, bacteria, or trapped moisture that lies under the material. Odours that exist on the surface can be removed through vacuuming and proper maintenance at home, but stubborn odours will need more attention.


Upholstery cleaning is a service that ensures the elimination of the substances causing these odours from your couch, giving you a clean and lasting solution. If you want dependable couch and upholstery cleaning services in London, St. Thomas, and surrounding areas, turn to Railway City Carpet Cleaning.
