How to Get Mold Out of Carpet: A Step By Step Guide

If you discover mold in your home, it’s crucial to remove it promptly due to the potential health hazards it poses. While cleaning hard surfaces like metal or concrete is relatively straightforward, dealing with mold on soft surfaces like carpets requires specialized techniques. This article explores why mold grows on carpets, the risks it poses, and effective methods to eliminate it.

Understanding Carpet Mold Growth

Mold, a fungus spreading through airborne spores, thrives in moist environments. Carpets, with their ability to trap moisture, provide an ideal breeding ground for mold. When a carpet gets wet, whether due to leaks, floods, or high humidity, moisture becomes trapped within its fibers and underlying structure.

If left unaddressed, mold can quickly develop and spread, especially in hidden areas like closets or beneath furniture where moisture might go unnoticed.

The Serious Consequences of Carpet Mold

Carpet mold isn’t just unsightly; it significantly impacts indoor air quality. Inhaling mold spores can lead to various health issues, particularly in individuals sensitive to mold. The Centers for Disease Control (CDC) link mold exposure to upper respiratory symptoms, worsened asthma, and eye irritation.

Additionally, mold can trigger allergic reactions, making it especially concerning for children who often play on the floor. Beyond health concerns, mold also produces a musty odor and can damage the surfaces it grows on, potentially harming your floors and baseboards.

How to Get Mold Out of Carpet: A Step By Step Guide

Step 1: Ventilate the Room

Start by opening windows and doors to let fresh air in and allow moisture and odor to escape. Protect yourself by wearing a facemask, rubber gloves, and eye protection.

If possible, take the affected rug outside for about 48 hours to air it out.

Step 2: Address the Moldy Area

If the mold is confined to a small spot, you can clean it. If it’s on the carpet backing or widespread, replacing the carpet might be necessary.

For smaller areas, carefully cut out the moldy section, leaving a 12-inch border. Replace the removed piece with a new one. If this doesn’t work, consider replacing the entire carpet.

Step 3: Use Baking Soda and Vinegar

Sprinkle baking soda over the moldy area and let it sit overnight. Baking soda helps absorb moisture and odors.

The next day, apply vinegar to the mold spots and scrub the surface using a scrub brush. Don’t forget to clean the back of the rug or carpet.

Step 4: Vacuum with HEPA Filter or Use a Broom

If your vacuum has a HEPA filter, vacuum the area thoroughly. Ensure you change the filter afterward to prevent spreading mold spores.

If your vacuum lacks a HEPA filter, use a broom and dustpan instead. Dispose of the remnants directly into a trash bag to prevent spores from getting into the air.

Step 5: Drying the Area

After cleaning, the carpet will be damp from the vinegar. Use natural methods to dry the area, such as opening windows or using a fan or dehumidifier.

White distilled vinegar is an excellent cleaning agent that’s safe for your health and the environment, making it a preferable choice over harsh chemicals like bleach.

Step 6: Try an Anti-Fungal Spray

If baking soda and vinegar don’t work, opt for an anti-fungal spray specifically designed for carpets. Avoid using bleach to protect your respiratory health and the environment.

You can find suitable anti-fungal sprays online or at local hardware stores. Ensure the product is safe for use on carpets before applying it to the affected area.

How to Use Anti-Fungal Spray to Remove Mold

  1. Spray and Wait: Apply the anti-fungal spray directly onto the mold and extend about 6 inches beyond the affected area. Let it sit for an hour.
  2. Blot and Wait: After an hour, blot the area with a disposable rag to soak up excess spray. Allow it to sit for 24 hours. Avoid trying to dry it manually; instead, use a dehumidifier or increase room heat to allow natural drying. Keep the room closed and avoid letting pets or children near the treated area.
  3. Clean Tools: Wash the scrub brush with warm soapy water to remove any mold residue, ensuring mold spores don’t spread.
  4. Repeat Treatment: Once the carpet is dry, repeat the spraying process. Use a clean rag to blot and continue running the dehumidifier or heat for a few more days to confirm the mold is entirely eradicated.
  5. Regular Checks: Monitor the carpet periodically, especially in the first few weeks and again after one month, to ensure the mold doesn’t reappear.

Additional Tips for Mold Prevention

  1. Use Mats: Place mats under potted plants to prevent moisture buildup and mold growth under them.
  2. Firewood Barrier: Create a moisture barrier between firewood and the carpet to avoid mold formation.
  3. Dehumidifiers: Maintain humidity levels below 60% with dehumidifiers, saving your floors and artwork from moisture damage.
  4. Air Purifiers: Use air purifiers to remove spores from the air, particularly beneficial for those sensitive to mold.
  5. AC Settings: Run the air conditioner on the “auto” setting to maintain lower indoor humidity levels.

Home Maintenance Tips to Prevent Mold

  1. Regular Air Filter Replacement: Change air filters every three months, ensuring they filter out allergens like mold and dust.
  2. Frequent Vacuuming: Regularly vacuum your home to remove mold spores that may be brought inside.
  3. Exterior Painting: Stay proactive with exterior home painting to prevent water infiltration. Low-quality paints used by builders can lead to water damage.
  4. Roof Maintenance: After storms, inspect the roof for leaks or damage. Ensure shingles are intact, and gutters are clear to prevent water from seeping into your home.
