Has your carpet started giving off a musty odor that just won’t go away? That unpleasant mildew smell can spread quickly and make your whole home feel damp and unclean. The good news?
You don’t need to panic. With the right techniques and a few household supplies, you can remove the mildew smell from your carpet and keep your home feeling fresh.
Whether the cause is past water damage, excess moisture, or hidden mold and mildew, this guide will walk you through practical, effective ways to get the mildew smell out of carpet, without costly mistakes. Let’s figure this out together.
Understanding the Musty Carpet Odor: What Causes It?
Before diving into solutions, it’s helpful to understand what causes that musty smell from your carpet in the first place.
- Excess moisture or humidity: A humid environment or poor ventilation can cause mildew growth.
- Water damage: Spills, leaks, or flooding can soak the carpet padding, leading to bacterial and mildew development.
- Poor drying after carpet cleaning: When you clean the carpet but don’t let it dry thoroughly, mildew and odors can follow.
- Dust and debris: Trapped dirt in carpet fibers can contribute to bacteria, mold spores, and that lingering musty odor.
In homes throughout Los Angeles, basements and bathrooms are common mildew hotspots due to higher humidity and poor airflow.
How to Get Mildew Smell Out of Carpet: Step-by-Step Cleaning Tips
Let’s walk through the best ways to remove mildew smell from your carpet and restore clean indoor air quality.
Step 1: Air and Carpet Ventilation
Ventilation is your first line of defense.
- Open windows to increase airflow and push contaminated indoor air out.
- Use fans or a dehumidifier to reduce humidity. Lower humidity helps prevent mildew and mold growth.
- If you have access underneath, lift the carpet to let air circulate and fully dry any trapped moisture.
Step 2: Vacuum the Carpet Thoroughly
Remove all dirt, dust, and debris trapped in the carpet fibers using a vacuum cleaner with a HEPA air filter.
- This prevents dirt buildup, which contributes to mildew odor over time.
- Pay extra attention to the affected area where the mildew smell is most concentrated.
Step 3: Treat with Vinegar and Water Cleaning Solution
White vinegar is a powerful and natural cleaner that can help eliminate mildew.
- Mix equal parts white vinegar and water in a spray bottle.
- Lightly spray the affected area without oversaturating the carpet.
- Allow the vinegar to sit for 10 to 15 minutes to break down mildew and neutralize odor.
- Blot the area with a towel or clean cloth to absorb excess moisture.
Step 4: Apply Baking Soda to Absorb Odors
Sodium bicarbonate (baking soda) is well-known for its odor-absorbing properties and is safe for most textiles.
- Sprinkle a generous amount of baking soda on the carpet, focusing on smelly spots.
- Gently work the baking soda into the carpet using a sponge or soft brush.
- Let the baking soda sit overnight (or at least 6 hours) to absorb mildew and musty smells.
- Vacuum the carpet once more to remove all residue.
This method helps freshen the carpet while absorbing deep-seated moldy odor caused by spores hiding in the fibers.
Step 5: Deep Clean with Carpet Shampoo or Steam Cleaner
For persistent smells, it may be time to clean the carpet using a steam cleaner or carpet shampoo.
- Use a cleaning solution that specifically targets mildew and mold.
- Make sure not to oversaturate the carpet; excess water can worsen the smell.
- Drying the carpet thoroughly after shampooing is crucial to prevent mildew growth and eliminate mildew odors.
You can rent carpet shampooers at most home improvement stores in Los Angeles or contact local professional carpet cleaning services if DIY isn’t delivering the results you need.
Advanced Tips to Eliminate Mildew and Prevent Future Smells
Once you’ve removed the smell, take extra steps to ensure it doesn’t come back.
Use Carpet Deodorizers and Air Purifiers
- Select carpet deodorizers safe for home carpet materials. These not only mask but help remove odors at the source.
- Install a HEPA air purifier to trap bacteria, mold spores, and air pollution that can lead to mildew odors.
Prevent Mildew Smells with Proper Maintenance
- Vacuum regularly to minimize dust, allergens, and moisture retention that can lead to mildew.
- Avoid leaving wet carpet untreated. After spills and stains, always blot and dry immediately.
- Keep indoor humidity under control using a dehumidifier, especially in high-risk areas like bathrooms and basements.
- Maintain good airflow with open windows and ceiling fans.
Proper humidity control and routine cleaning steps go a long way in keeping your carpets fresh and your home healthy.
Check Underneath the Carpet Padding
In many cases, mildew smell from your carpet means it has spread to the carpet padding. If that’s the case:
- Consider lifting the carpet to inspect the padding.
- If it’s fully soaked or smells moldy, it’s time to replace the padding.
- This will prevent the growth of mold and mildew from recurring and restore your indoor air quality.
When to Call in Professional Cleaning Services
Sometimes DIY carpet cleaning doesn’t go far enough. If the smell of mildew lingers even after trying the steps above, mold or mildew growth may have spread deep into your carpet fibers and padding.
In that case, reach out to professional cleaning services in Los Angeles. A professional carpet cleaning service uses steam extraction, high-powered dryers, and advanced cleaning products to remove mildew odor from carpet and prevent future growth.
Trained cleaners can also identify signs of deeper damage like indoor mold, flood issues, or water extraction needs before they lead to more serious health concerns.
Natural Alternatives and Home Remedies That Actually Work
You don’t have to use chemicals to get your home fresh and clean. Here are a couple of natural solutions worth trying:
- Hydrogen peroxide (3%): Can help remove stubborn stains and kill mildew. Use with caution, always patch test first.
- Vinegar and baking soda mixture: The bubbling reaction lifts odors and breaks down surface-level mildew. This combo remains one of the best ways to remove mildew smell out of carpet naturally.
- Essential oils: A few drops of tea tree or eucalyptus oil can help rid your carpet of musty grease and leave behind a clean scent. Just don’t rely on fragrance alone to solve the issue.
