The most common cause of a bad smell after carpet cleaning is excess moisture that has not been properly extracted, leading to the growth of mildew or mold in the carpet fibers or underlying padding.
If your carpet smells bad after cleaning, there are a few effective steps you can take to address the issue and restore freshness to your home.
In addition to extracting the water during a carpet cleaning, you also want to get some air moving. Drying carpet after carpet cleaning should always be a focal point to keep things from smelling musty. How long it takes for carpet to dry can vary but usually it shouldn't take more than half a day.
For the general population, the amounts of VOCs from carpet and adhesives do not appear to affect health. However, for the young, older adults, and people with lung conditions, allergies and allergic-type sensitivities, fairly low amounts of VOCs may have health effects.
If your room smells musty, it could be caused by something called microbial volatile organic compounds (mVOCs). The Environmental Protection Agency says, "Because mVOCs often have strong or unpleasant odors, they can be the source of the "moldy odor" or musty smell frequently associated with mold growth.
One of the easiest ways to detect it is by smell—black mold emits a strong, musty odor often compared to rotting plants, damp paper, or cedar wood. If you're unsure whether you're detecting mold, ask someone with a “fresh nose” to confirm, as you may have become desensitized to the smell in your home.
How to Deodorize a Room (Step-by-Step)
Carpet cleaning chemicals have been known to contain surfactants which is known for causing skin problems among workers, fragrances and disinfectants may cause chronic respiratory problems. Asthma, or allergic reactions have been affiliated with dried detergent residues from carpet cleaning chemicals.
A Musty Odor
Common types of mold release microbial volatile organic compounds (mVOCs) that produce an earthy, musty smell. If you notice this odor persisting or worsening around your carpets, it could be a sign of mold or mildew and should be investigated.
Nonenal odor, also known as “old person smell” or “old people smell”, is a harmless scent that is associated with the elderly. It is often described as having a greasy, pungent, and musty odor.
The new carpet smell is unlikely to be harmful long term, though it can cause some short-term symptoms in the form of headaches, dizziness, and mild nose and throat irritation. Sensitive groups, like newborns and those with a history of respiratory issues, may react more strongly.
Have you noticed that after a traditional carpet cleaning it takes a day or more for your carpet to fully dry? That is happy hour for mold! Mold spores use that as their time to shine- if your carpet is soaked for more than 24 hours, you may have a problem.
Fresh air circulation is essential in helping VOCs escape from the room rather than being trapped indoors. To improve ventilation, open windows and doors, and consider using fans to increase airflow. If the weather allows, leave windows open for the first few days after installation to let VOCs disperse more quickly.
A thorough vacuum after drying helps lift the carpet pile and remove any loosened soil left behind during cleaning. This is especially important if the method used was hot water extraction, which can bring deeply embedded dirt to the surface as it dries.
Put warm water and a few drops of Dawn in a spray bottle or garden pressure sprayer and spray your upholstery or carpet. Then use only clean water in the Bissell to clean. Don't put Dawn in the machine.
Typically, a light, clean scent might linger for 12 to 24 hours. If proper drying methods are used, any noticeable smell should fade within 1 to 2 days.
Recognizing the warning signs of mold toxicity is crucial for early intervention and prevention of potential long-term health problems.
Identifying mold in your carpet involves looking for several telltale signs of a moldy carpet:
Food and drinks account for most spills. As an organic material, just like pet messes, the bacteria associated with food and drink release unpleasant smells over time. Food and drink can also create some of the hardest smells to get out of your carpet.
Do you often sneeze, itch, or feel stuffy after spending time on your carpet? You might be dealing with a carpet allergy. Many people don't realize carpets can harbor allergens like dust mites, pet dander, and mold, which trigger uncomfortable symptoms in sensitive individuals.
Best practices for safety after carpet cleaning
First, allow sufficient drying time, ideally, wait at least 6 to 8 hours before re-entering the room, and aim for 24 hours for complete dryness.
Lungs are self-cleaning organs that will begin to heal themselves once they are no longer exposed to pollutants. The best way to ensure your lungs are healthy is by avoiding harmful toxins like cigarette smoke, vaping and air pollution, as well as getting regular exercise and eating well.
Sometimes, a deep cleaning isn't enough to completely eliminate mold and mildew smells. If foul odors persist, you may want to have a professional perform an indoor air quality test. A professional will also know what to look for and can identify signs of a more serious mold issue.
