If you’ve ever walked into a room and been hit with a musty, unpleasant smell, chances are you may have a mildew problem lurking in your carpet. Mildew not only smells bad, but it can also cause allergies and damage the fibers in your carpet if left untreated. Luckily, with a few simple steps, you can eliminate that mildew odor for good. In this guide, we’ll break down the causes of mildew, how to treat it, and how to prevent it from coming back. 


What Causes Mildew Smell in Carpets? 

Mildew is a type of fungus that thrives in moist, poorly ventilated areas. It’s not uncommon for carpets to trap moisture from spills, high humidity, or improper cleaning methods. If moisture remains in the carpet fibers, mildew can form, leading to that familiar musty smell. 

Common Causes of Mildew in Carpets: 

  • Spills or Leaks: Carpets that have absorbed moisture from spills or leaks are prime candidates for mildew growth. 
  • High Humidity: In rooms with high humidity, carpets can retain moisture, leading to mildew. 
  • Poor Ventilation: Rooms with little to no ventilation make it hard for carpets to dry properly after cleaning or exposure to water. 

Identifying the root cause of the mildew is essential for successful treatment. If you leave the source untreated, mildew is likely to return. 


Step 1: Identify the Source of the Mildew Odor 

Before you begin cleaning, it’s important to pinpoint exactly where the mildew odor is coming from. If the smell permeates an entire room, the source could be a widespread moisture issue, such as a leak under the floor. If the smell is localized, it may be the result of a spill or damp spot that wasn’t dried thoroughly. 

  • Tip: Walk over the carpet and check for any wet or damp areas. The area that smells the strongest is likely where the mildew is concentrated. 
  • Check for Hidden Moisture: Use a moisture meter or inspect the carpet padding underneath if the source isn’t immediately obvious. 

Step 2: Dry the Affected Area Thoroughly 

Mildew thrives in moist environments, so the next critical step is to dry the affected area thoroughly. 

Drying Methods: 

  • Use Fans: Place fans near the affected area to increase air circulation. This helps to dry the carpet faster and reduce humidity levels. 
  • Dehumidifier: For rooms with high humidity, a dehumidifier can help remove moisture from the air and dry your carpet faster. 
  • Sunlight: If possible, open windows and allow natural sunlight to reach the carpet. Sunlight has natural antibacterial properties that can help kill mold and mildew spores. 
  • Absorb Excess Moisture: Use towels or microfiber cloths to soak up as much moisture as possible from the carpet. 

By drying the carpet thoroughly, you prevent any further growth of mildew and make it easier to clean. 


Step 3: Sprinkle Baking Soda Over the Carpet 

Baking soda is an effective natural odor absorber and works wonders for mildew smell in carpets. It’s easy to use and helps to draw out both moisture and odor. 

How to Use Baking Soda on Carpet: 

  1. Sprinkle Baking Soda: Generously sprinkle baking soda over the area that smells of mildew. 
  1. Let It Sit: Allow the baking soda to sit on the carpet for several hours, or even overnight for more effective odor removal. 
  1. Vacuum It Up: Once the baking soda has had time to absorb the smell, vacuum the area thoroughly. 

The baking soda will help neutralize the mildew odor, leaving your carpet fresher. 


Step 4: Use Vinegar or a Mildew-Specific Carpet Cleaner 

Vinegar is another powerful and natural remedy for removing mildew odors. If you prefer a commercial product, look for a mildew-specific carpet cleaner that targets mold and mildew stains. 

How to Clean Carpet with Vinegar: 

  1. Mix Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. 
  1. Spray the Affected Area: Spray the solution onto the affected part of the carpet. 
  1. Let It Sit: Allow the vinegar to sit for 15-20 minutes to break down the mildew. 
  1. Blot the Area: Use a clean cloth or sponge to blot and absorb the solution from the carpet. 
  1. Rinse: Rinse the area with clean water and dry it thoroughly with fans or a dehumidifier. 

Vinegar is a natural disinfectant and can kill the mildew spores, effectively eliminating the smell. 


Step 5: Vacuum the Carpet to Remove Odor-Absorbing Agents 

Once you’ve applied your cleaning solution and allowed it to sit, it’s time to vacuum the carpet to remove any remaining baking soda, dirt, and mildew particles. 

How to Vacuum the Carpet: 

  1. Use a HEPA Vacuum: A vacuum with a HEPA filter is the most effective at trapping fine mildew particles. 
  1. Vacuum Slowly: Move the vacuum slowly over the affected area to ensure thorough cleaning. 
  1. Dispose of Vacuum Bag/Filter: If your vacuum uses a bag or filter, make sure to dispose of it afterward to prevent spreading mildew spores. 

Vacuuming helps remove any remaining residue from your carpet, leaving it clean and fresh. 


Step 6: Use a Carpet Deodorizer for Long-Lasting Freshness 

To ensure long-lasting freshness, consider applying a commercial carpet deodorizer or a DIY spray using essential oils. 

Deodorizing Options: 

  • Commercial Carpet Deodorizer: Follow the instructions on the product label, and spray it evenly over the cleaned area. 
  • DIY Essential Oil Spray: Mix water with a few drops of essential oil (such as lavender or tea tree) and lightly spray the carpet. 

This final step helps to neutralize any lingering odors and keep your carpet smelling fresh for days. 


Step 7: Prevent Future Mildew Growth with Regular Maintenance 

After removing the mildew, it’s crucial to take preventive measures to stop it from returning. 

Prevention Tips: 

  • Dry Spills Immediately: Any time there’s a spill or leak, clean it up immediately and dry the area thoroughly. 
  • Improve Ventilation: Keep rooms well-ventilated by using fans or opening windows to prevent moisture buildup. 
  • Regular Carpet Cleaning: Clean your carpets regularly, especially in areas prone to spills or high humidity. 
  • Use Dehumidifiers: Consider running a dehumidifier in rooms that have high humidity, such as basements or bathrooms, to reduce moisture levels. 

With regular maintenance and proper care, you can prevent mildew from reappearing in your carpet.
