How to Get Mildew Smell Out of Carpet

Mildew smells can be an eyesore and even lead to allergy or respiratory symptoms if left untreated; for this reason, it’s vital that action are taken swiftly to eliminate them as soon as possible.

Mildew is a type of fungus found in moist environments. Although less toxic than mold, mildew still poses health threats if left unchecked.


Vinegar is an effective, eco-friendly cleaning solution that is widely used and affordable. Not only is it cost effective and cheap to use, it also contains antibacterial and antifungal properties to remove stains, odors, and mildew build-up from surfaces in your kitchen and bathroom.

Locating and eliminating musty and mildew odors can be an uphill battle. You may need to employ multiple solutions in order to restore a fresh-smelling carpet surface.

An effective solution for eliminating mold and mildew from carpets is mixing vinegar with baking soda, as the latter will neutralize its odor while the former works to kill off the mold spores that are the source of your trouble.

Sprinkle the vinegar and baking soda mixture liberally over your carpet and allow it to sit for several hours or overnight, giving natural deodorizers time to do their work and eliminate musty smells from your rug.

An effective way of eliminating mildew odor is mixing one part hydrogen peroxide with five parts water in a spray bottle and applying. This solution will kill mold spores that contribute to its musty odor as well as help get rid of mildew smell.

Add dish soap to make the solution even more effective, as it will help break down spores further and increase its efficacy.

Dish soap will assist in dispersing the mixture of vinegar and baking soda to reach deeper into your carpet fibers, eventually eliminating its smell altogether. Repeating this step several times until all odor has dissipated completely.

Vinegar can be an effective, safe way to get your carpets clean, but before using this solution on an entire room or area it is wise to do a small test area to determine its impact on its color, texture, smell, or other factors that could alter its aesthetics or appearance.

Baking Soda

Baking soda is an affordable, all-natural solution to help eliminate mildew smell in carpeting. Not only is it nontoxic to humans and pets alike, it can even be beneficial in eliminating mildew smell altogether!

Step one is to use baking soda sparingly over any grease-based stains like pizza, oil or mayonnaise; however, this technique works equally well on non-greasy stains such as mud, wine or blood stains.

Once the baking soda has been applied to the stain, wet a paper towel or washcloth with hot water and press it into it until all traces of staining have been eliminated. Repeat if necessary until stain is gone completely.

Once the stain has been eliminated, vacuum it up. However, be aware that this process may leave some baking soda residue behind in your carpet which may be more difficult to remove; to allow this time for removal it’s recommended that at least 48 hours pass before vacuuming again.

Next, use a vinegar and water solution on the affected areas of your carpet to absorb any mildew odors that have permeated, as this will prevent further growth of mold or mildew. Be cautious not to overwet it as overdamping may cause mold or mildew growth in other parts of the carpet.

Hydrogen Peroxide

Hydrogen peroxide is one of the best ways to remove mildew smell from carpet, acting as a powerful cleaning agent and killing bacteria, viruses, and fungi – providing an effective disinfectant solution.

Hydrogen peroxide in its pure state is an innocuous-colored liquid with slightly greater viscosity than water and acts as a powerful oxidizer, often used as bleaching agent.

Natural and eco-friendly disinfecting agents such as vinegar are an ideal way to keep your home free of germs without harming the environment. Furthermore, vinegar has proven highly useful as an ingredient in cleaning products as it helps remove mold from carpeting.

Hydrogen peroxide can also be an excellent way to clean fruits and vegetables exposed to high moisture levels, helping eliminate any bacteria-causing odors and leave behind fresh and nutritious produce.

Not surprisingly, the concentration of hydrogen peroxide you choose to use is of vital importance; various strengths are available – with 3% being the most widely-used option.

High concentrations can be hazardous, so it is advisable that this mixture only be used in a well-ventilated area in order to avoid getting it in your eyes or mouth. This will also keep the product away from coming in contact with it and possibly contaminating it further.

If you have a mildew problem, it’s crucial to address it quickly and safely – particularly if children, pets, or those with respiratory conditions could be negatively impacted by prolonged exposure.

If you are experiencing severe mildew issues, professional assistance should be sought immediately. A qualified mold removal service provider can identify the type of mildew present and suggest ways to eliminate it effectively; they also offer tips on making cleanup as painless as possible.


Mildew is an irritating type of fungus that can quickly take over a home, damaging natural fibers while leaving behind stain marks and an unpleasant aroma.

Mildew can spread quickly throughout a home, settling on dark, damp surfaces before emitting gasses that worsen its odor and release toxic spores that pose health threats to human respiratory systems.

if your carpet has an unpleasant mildew smell, there are a few steps you can take to remedy the situation and rid yourself of its scent. First and foremost, find the source of this offensive aroma; for instance if it emanates from an issue within your home such as a leak in a pipe, fix that immediately to alleviate further problems with its source.

Use detergents that help eliminate mildew odor in carpets as another step towards eliminating mildew smell. Detergents are chemicals used as surfactants; this means they have surface-active properties capable of dislodging and suspending foreign materials on surfaces.

Many detergents feature hydrophobic and hydrophilic groups like fatty acids or C-C chains; others feature compounds with sulfo groups (such as sulfur-containing compounds) to make them water soluble; others rely on an organic acid or long ethylene oxide chain that acts nonionically to dissolve water-soluble compounds.

Many of these solutions are commercially available or can be obtained at drug stores. If you decide to use one of them, be sure to follow all directions carefully and rinse well afterward; repeated treatments may be necessary if your carpet is heavily trafficked.

Chlorine Dioxide

Chlorine dioxide is an extremely effective disinfectant that can eliminate mildew odor and kill bacteria and fungi safely and quickly, making it suitable for hospitals and water treatment plants. It’s often employed to ensure an environment-healthy atmosphere.

To effectively use chlorine dioxide, it’s essential to understand its properties. Most importantly, chlorine dioxide does not react with organic materials like chlorine does – meaning no trihalomethanes (THMs) or haloacetic acids that could potentially harm the environment are produced as a result. In addition, it does not stain or corrode surfaces like other disinfectants might do.

Second, this treatment is highly efficient in numerous applications, from cleaning sewage and industrial waste to eliminating unpleasant smells in animal byproduct rendering plants.

Finally, it is an environmentally-safe disinfectant suitable for use around children and animals, making it an excellent choice in hotels, hospitals, or any crowded environments.

Mildew smell can be eliminated on carpets, upholstery and fabric with this non-toxic EPA and FDA-approved gas that won’t stain or corrode surfaces.

However, chlorine dioxide is less stable than ozone and may decompose into chlorine and oxygen at partial pressures above 10kPa (1.5 psi), potentially creating dangerous concentrations of chlorine dioxide vapor that can result in fires or explosions if left in enclosed spaces. Therefore it is advised that users wear NIOSH-approved respirators when working with high concentrations of this product in enclosed spaces to protect them against fire or explosion hazards. Also follow manufacturer directions when diluting and applying in order to ensure safety of all involved ensuring all present are kept safe.
