How To Get Mildew And Its Smell Out Of A Rug?

2025-05-07
You might place your favorite traditional rug inside the home or outside. If the rug gets wet due to a spill or rainwater and is left unattended, there’s a chance it will develop mildew and smell bad. The good news is that you can remove the fungal spores from the rug. While it will take some time, you can do this with just a few ingredients at home.
What Is Mildew?
Mildew is a comprehensive term for mold or fungus. The growth of these spores can cause allergic reactions in sensitive people when inhaled. Unfortunately, mildew can thrive on most organic matter, including your favorite rug. If a surface is wet and dusty, the spores can feed on them. As a consequence, they grow and spread.
Identifying Mildew Growth On A Rug
Before learning about how to get mildew out of a rug, you should learn to identify its occurrence. The most common identifier for its growth is mildew visible atop the rug. But you could look for these other indicators.
Discoloration
Sometimes, a rug develops a dark or discolored section. This might be a chemical reaction to dampness. If there is no other reason for the discoloration, it might be a mildew problem.
Folding Or Curling
Press down on the rug. If it folds with the pressure, there might be spores of mildew present. Even if parts of the material look like they curl under, moisture might be crawling into it and causing mold growth.

Musty Odor
The odor of these fungal particles is distinct and off-putting. So a rug with an unprecedented odor might have mildew growth.
Unusual Allergies
Getting an allergy without an underlying condition is one sign of mildew growth. If you’re allergic to the spores, you might experience mild symptoms like coughing, sneezing, skin and eye irritation, and a sore throat. A more severe reaction might be trouble breathing.
A Burning Smell Or Appearance
Spores of mildew can burn under the light of the sun, leaving behind a burning smell. You may even notice the edges of the rug look burnt.
Home Ingredients To Remove Mildew From A Rug
If you see any of the above signs, you should learn how to get mildew and its smell out of the rug. First, you must gather some common home ingredients.
Baking Soda:
This natural deodorizer could get rid of the smell and freshen the rug.
Vinegar:
Vinegar focuses on mildew spores that may grow on the rug and eliminates them.
Rubbing Alcohol:
The solution is concentrated with isopropyl alcohol, water, and other chemicals. So, it is ideal for removing mildew from a rug that isn’t too damp in small to medium areas.
Hydrogen Peroxide:
You could use hydrogen peroxide for mildew stains that do not go away even after applying vinegar or baking soda. But do not use it in a concentrated form. Instead, add five parts of water with one part of hydrogen to a spray bottle.
Steps To Remove Mildew And Its Odor From The Rug
You now know how to identify mildew growth and the ingredients needed to remove it. Next, follow this step-by-step guide to remove the spore growth and its odor.
Dry The Area
After you have located the source of the odor, you must work toward drying the area.
Fix the leak or spill and dry the area.
You could also pull back the rug's edges or remove the baseboard to let air circulate.
A dehumidifier can get rid of moisture from the air and the rug.
Some rugs might have extra padding that goes damp with water. Replace it to prevent the smell from coming back.
Vacuum The Rug
After drying, you must:
Vacuum the entire rug in straight lines. Overlap each line by at least 50% when vacuuming a line parallel to it. The vacuum may have special tools, including a crevice attachment. Use it to access hard-to-reach regions.
Empty the vacuum and clean the filters after each use. It will prevent mildew spores from recurring in the rug.
You might have to vacuum the area a few times to get all the spores out.
Apply A Cleaning Solution
Vacuuming is great. But, it’ll only reduce the mildew in the rug for so long. To sanitize the rug, apply a cleaning solution from one of four home remedies from earlier. You could:
Sprinkle baking soda on the fibers.
Use rubbing alcohol to clean small to medium areas, only if the rug isn’t too damp.
Apply a hydrogen peroxide mixture on the rug to target spores.
Spray vinegar on the rug, but with personal protective gear.
These options should help tackle a specific stage of mildew spread and effectively clean the rug.
Scrub The Rug
Scrubbing the rug is another important aspect of getting mildew out. After applying the cleaning solution, you must:
Use an old scrubbing brush, toothbrush, or scrub pad to scrub the mildew-infested areas. For larger areas, borrow or rent an electric scrubber or steam cleaner.
Scrub it in small circles, work from the outside in, and let it sit for about 30 minutes.
Next, use a towel or a wet and dry vacuum to absorb most of the moisture from the rug.
Rinse the rug with water to remove residue. Repeat this a few times for tougher stains.
Cleaning solutions, even at-home solutions, release chemical fumes. Ventilate the room by opening the windows.
You can also use an air purifier to remove musty smells from the room.
Let It Dry
You can open the windows to help with the drying. But to expedite the drying process, our experts at Gooviedo recommend some additional measures:
Turn on nearby fans and keep them aimed at the rug to keep the air flowing. The fibers may take between 8 to 24 hours to dry based on its size.
Avoid walking on the rug while it dries. Stepping on it could push the mildew deeper into the fibers.
Sprinkle Baking Soda To Deodorize
You can sprinkle baking soda on the rug and let it sit overnight. The powder should absorb the mildew and musty smells. Next, vacuum the baking soda the following morning with the hose or brush attachment on the appliance.
If The Issue Persists, Hire An Expert
If you have tried everything and the stain or odor of mildew still does not go away, you ought to hire an expert. The expert may know other ways to clean the rug and remove odors. 
Tips To Prevent Mildew Growth And Smell On Rugs
Apart from the steps above, you can take measures to prevent mildew from growing in the first place.
Maintain Low Humidity Levels
Mildew growth is often the consequential result of moisture in the air. Use an air purifier with a HEPA filter to remove moisture from the home and improve ventilation.
Clean Spills Quickly
A spill is a focal point for mildew growth and musty odors. Blot the spill with an absorbent cloth and dry the region. A large spill might require additional ventilation, such as a fan, to dry the area quickly.
Vacuum Frequently
Mildew usually thrives in areas with dirt and debris. You should vacuum the rug at least once a month to get the particles out.
Get Antimicrobial Padding
Antimicrobial padding for rugs disperses silver ions, which can kill mildew spores. Check for padding with permanent antimicrobial agents. It will also keep the rug fresh.
Look For Rug Alternatives
Some homes may have too much moisture. The ideal solution is to switch to more viable alternatives, like nylon or polypropylene rugs. The synthetic nature is water-resistant. Moreover, Berber-style rugs are ideal for high-moisture areas, including basements, as they dry quickly.
