Are you starting to notice allergy-like symptoms? Or perhaps you’re experiencing more asthma episodes than normal. Mold in your carpet might be the cause.

Mould in a carpet isn’t always apparent; it might grow inside the pad, which can be difficult to identify. It can even grow in the fibres at times. In any case, it is critical to destroy and eliminate mould. You might be feeling a little bewildered right now, but we’re here to assist with our comprehensive guide to cleaning mould from carpet.

Is Carpet Mold Harmful?

Mould is a naturally occurring fungus that may grow both inside and outdoors. When you’re inside, though, it might be hazardous to your health.

Mould exposure can have a range of health impacts – or none at all. Some individuals will be unaffected, while others may have severe responses. People who are allergic to mould or have weakened immune systems may get interior illnesses.

The Institute of Medicine found adequate evidence tying mould to respiratory tract problems in a 2004 research. Coughing and wheeze were reported in apparently healthy persons. It also revealed an increase in asthma episodes in people who previously had asthma.

Carpet mould is extremely hazardous since we are constantly exposed to it. If the afflicted carpet is in the living room or bedroom, our health is jeopardized even more — particularly due to chemical interactions in mould cells.

How to Spot Carpet Mold

Mould is not always apparent on the surface of carpets, therefore you must rely on other indicators as well. These are some examples:

  • Visible mould growth: Mold favours a dark environment, although it can grow on the fibres in extreme situations. So, while examining for mould, go beneath the carpet – and don’t forget to check the cushioning.
  • Mildew in carpet: Mildew is frequently the beginning of a mould problem. The colour is the easiest method to distinguish the two differently. Mildew is white, whereas mould is black, blue, red, or green.
  • Mould will begin to develop within 24 to 48 hours after being exposed to water, so you must act quickly.
  • Stains and scents: Musty, nasty, and sour aromas are common indicators of mold. Mold can be identified by stains or discolorations. However, if you want to be certain, you may get a sample test performed by specialists.

Don’t give up! Fortunately, there are methods for bringing your carpet back to life. In this guide, we’ll show you a few examples.

How to Get Mold Out of Carpet Naturally

That’s correct, eradicating mould from your carpet doesn’t always necessitate the use of harsh chemicals. If you have children or pets, this may be the best option. All you need is baking soda, vinegar, and some fresh air:

Inspect Carpet

Use the above technique to assess whether you have mould. Then, check further to determine the location of the mould. Is it in the threads? Is it in the padding? Examine the whole carpet to ensure that you have found every possible source of mould.


Mould needs darkness, moisture, and warmth to thrive. Opening a window or putting on a fan might help to minimize humidity in the space. This will help lessen the negative effects, such as the foul odour.

Baking Soda

Moisture is one of the most important elements mould requires to flourish. As a result, it is critical to eliminate this component.

Baking soda is quite good for absorbing moisture and eliminating smells. Apply generously to the afflicted region and keep it on overnight. Use a vacuum to remove the baking soda the next morning.

You may also use cat litter as a replacement because it is extremely efficient at absorbing liquids.


Vinegar is a versatile substance that may be used for a variety of purposes, including eliminating mould spots. It won’t destroy every type of mould, but it will get rid of it. Vinegar is also an inexpensive and healthful alternative to chemicals.

Take extra caution when using vinegar near hardwood flooring. While vinegar has many advantages, if not used properly, it can damage hardwood.

Fill a spray bottle halfway with pure vinegar and prepare a stiff brush. Scrub with a thin layer of vinegar. Finish with a blow dryer or fan to remove any remaining moisture.

How to Clean Mold from Carpet Using Chemicals

If you want to permanently eliminate mould, you must employ chemicals. You may even seek expert assistance if you believe it is necessary.

Begin by treating your carpet using the above-mentioned processes one, two, and three. Then try one of the following approaches:

Anti-Mould Treatment

Anti-mould cleansers are available at most supply and hardware stores. There are also several options accessible on websites such as Amazon and Home Depot.

When selecting a product, look for one that is carpet-safe. Carpet may be damaged or discoloured if a product intended for kitchens or bathrooms is used.

Concrobium’s Duo Blast is one of our favourite products. It is made up of two formulations that efficiently remove mould, mildew, and the stains that they leave behind.

If your carpet is in a high-traffic area and you want to avoid future mould growth, you can use specific solutions. These are referred to as “encapsulates” or “mould-barriers.”

You may also mix bleach and water to make your own mould-blasting solution. In a gallon of water, combine half a cup of colour-safe bleach.

Because it is bleach, test it first in an inconspicuous location.

Follow the directions on the anti-mould treatment. Bleach should not be applied to the stain for more than a few minutes. Scrub and wipe it out with a firm brush, then repeat as needed.

Product for Carpet Cleaning

Carpet cleaners may be quite efficient in removing mould and mildew stains and odours. These may be purchased from any home improvement, hardware, or supply store. Amazon and Home Depot also have a large assortment.

However, before you choose a product, check sure it is safe for your carpet. Because no two carpets are similar, this should be examined. The information is clearly accessible in the product description or on the label.

The ZEP High-Traffic Carpet Cleaner is one of our favourites. Enzymes are used to break down stains and smells.

Follow the manufacturer’s directions while using the cleaner. Some products must be let to sit for a period of time, while others may require washing at the end.

Use Chlorine Dioxide.

Mould may be effectively removed with chlorine dioxide. It’s also a frequent ingredient in mould cleansers. However, use it with caution since the chemicals might cause carpet discoloration.

Chlorine dioxide can emit fumes that irritate the eyes and lungs. To be safe, do the therapy in a well-ventilated location and discontinue if you begin to cough or feel short of breath.

We strongly advise you to test it on a small area before using it. Follow the directions and wait for the area to completely dry before making a decision. At conclusion, some goods necessitate the use of a wet/dry vacuum.

Rent a Steam Cleaner

The high temperatures produced by a steam cleaner may efficiently destroy and eradicate mould. If you don’t already have a steam cleaner, you may rent one from a hardware shop.

After steaming the carpet, use a blow dryer or fan to dry it. Excess moisture might promote the growth of new mould.

Steam and hot water can easily cause damage or shrinkage to your carpet. To ensure that the task is done correctly, you should only utilize specialist equipment.

Leave It to the Professionals

If you’re feeling out of your depth, it might be advisable to seek expert assistance. Professional carpet cleaners will be able to diagnose and treat moulds in your carpet. They also have access to the necessary equipment and chemicals to eliminate the mould at its source.

Dry ice blasting is frequently used by professionals. This approach employs a pressured machine that sprays the region with the solid form of carbon dioxide known as dry ice.

If you’ve tried all of the aforementioned ways and still notice mould, there’s not much you can do. The mould has most likely contaminated the entire carpet, which must be discarded.

You can, however, choose to chop it off if it is only a tiny region, such as a corner. If you are hesitant, you may also leave this to the specialists. Measure out an additional 12 inches on all sides before you begin cutting the carpet. This will guarantee that all mould is removed.

How to Prevent Carpet Mold

The most effective approach to cure mould is to avoid it in the first place. To avoid future mould growth, follow these guidelines:


Increasing ventilation throughout your house can aid in the prevention of mould and mildew. Use a fan in a carpeted area or open the windows during the day to ventilate. We strongly advise you to practice this for at least two hours during the day.

It’s humid if it’s overcast and wet outdoors. Your windows should be closed during this weather. Otherwise, the damp atmosphere may find its way inside.

Use Dehumidifier

A dehumidifier is a great method to keep a humid atmosphere under control. To keep the gadget dry, position it so that it faces the carpet. It’s also a good idea to run it at night to get rid of any moisture in the air.

After washing the carpet, install a fan next to the dehumidifier to blow dry air over it.

Dry Carpets Well

Damp-prone areas should be addressed. Anti-moisture polyethylene sheeting might be useful in small areas between the carpet and the floor. The material will keep the space dry since it will keep water out.

Mould should also be checked in vents, upholstery, and closets. Spores are very contagious and may quickly spread throughout a house.

Vacuum Carpet

Although you may have removed the developing mould, spores may still be present inside the fibres. Mould may be kept at bay by vacuuming on a regular basis.

When eliminating a big colony of mould, a HEPA-filtered vacuum is quite successful. These employ a unique vent that collects and prevents small particles from entering the air. The Shark Navigator Upright Vacuum with HEPA filter is an excellent vacuum with a HEPA filter that captures 99.9% of allergens.
