I Tried Baking Soda and Vinegar on a Moldy Carpet—The Results Shocked Me!

April 21, 2025

A few weeks ago, I walked into my living room and caught a whiff of something musty. At first, I thought it might be the weather—it's been raining nonstop, and the humidity has been intense. But when I knelt down to check, I noticed small black spots spreading across the edge of the carpet.

That's when I knew I had a mold problem. And like many people, my first thought was to Google how to get mold out of carpet. What I found were dozens of expensive, chemical-laden cleaning solutions and professional services. But instead of spending hundreds of dollars or using harsh products, I decided to try something I already had in my kitchen: baking soda and vinegar.

The results? Honestly, I was stunned.

🦠 Why Carpet Mold Is a Serious Problem

Carpet mold isn't just an eyesore—it can be a health hazard. As someone who lives with young children and an elderly parent, I’m especially cautious about indoor air quality. Mold spores can trigger allergies, asthma, and even respiratory infections if left untreated. Unfortunately, carpets are a prime location for mold to grow, especially in damp or poorly ventilated areas.

If you're wondering how this happens: all it takes is a little moisture—maybe from a spill that wasn't dried properly, a pet accident, or even prolonged humidity. If the carpet backing remains damp, mold can start to grow within 24 to 48 hours. That’s why knowing how to get mold out of carpet quickly and safely is so important.

🧂 Why I Chose Baking Soda and Vinegar

I’m someone who avoids using harsh chemicals in my home whenever possible. I’m all about finding natural, eco-friendly solutions that are still effective—and this is where baking soda and vinegar come in. Together, they form a powerful duo:

  • Baking soda absorbs moisture and neutralizes odors.
  • White vinegar has antifungal and antibacterial properties that help break down mold at its source.

Best of all? They’re cheap, non-toxic, and already sitting in most kitchen cabinets.

🛠️ What You’ll Need

Before I started, I gathered the following materials:

  • 1 cup of baking soda
  • White vinegar (5% acidity)
  • A spray bottle
  • A soft-bristle brush or old toothbrush
  • Clean towels or microfiber cloths
  • A vacuum cleaner or wet/dry vacuum
  • Rubber gloves (optional)

I also made sure to open the windows and turn on a fan to help with ventilation and drying.

✅ Step-by-Step: How I Cleaned My Moldy Carpet

Step 1: Apply Baking Soda

I started by sprinkling a generous layer of baking soda over the affected areas. I used my fingers to gently pat it into the fibers. This step alone already helped neutralize some of the musty smell.

Step 2: Spray with Vinegar

Next, I filled a spray bottle with undiluted white vinegar and sprayed it evenly over the baking soda. The reaction created a fizzing sound and some bubbling—nothing dangerous, but it looked like the mixture was “eating” away at the mold.

Step 3: Gently Scrub the Area

After letting the mixture sit for about 10 minutes, I used a soft-bristle brush to gently scrub the area. I wasn’t too aggressive because I didn’t want to damage the carpet fibers.

Step 4: Let It Sit and Dry

I left the treated area alone for several hours, letting the baking soda and vinegar completely dry out. This part is key—the longer you let it sit, the better the results. If possible, I suggest doing this in the morning so you can let it dry all day.

Step 5: Vacuum Thoroughly

Once everything was dry, I used my vacuum cleaner to remove the residue. If you have a wet/dry vacuum, even better. When I checked the carpet afterward, the mold spots had vanished—and the smell? Completely gone.

🧠 What I Learned from the Experience

Honestly, I didn’t expect such powerful results from such a simple, all-natural remedy. I’ve spent years using store-bought cleaners that promise miracle results, but few of them worked as well as this DIY combo. And the best part? No harsh chemical smells, no concerns about my kids or pets being exposed to anything toxic.

When I first searched for how to get mold out of carpet, I saw dozens of methods, from using hydrogen peroxide to essential oils. Some might work, but I wanted something safe, accessible, and proven. After using this method, I can confidently say it’s worth trying before calling in professional cleaners.

💡 Bonus Tips from My Personal Experience

After doing this a few times, I’ve come up with some practical tips:

  • Don’t over-saturate the carpet with vinegar. A light spray is enough.
  • Always test on a small area first if your carpet is delicate or brightly colored.
  • Make sure the room is well-ventilated to speed up drying and prevent future mold growth.
  • Repeat the process weekly if the problem persists, or combine it with a dehumidifier for long-term control.

At this point, I can’t imagine using anything else. It’s cheap, safe, and incredibly effective. I’ve even used the same method on rugs, upholstery, and fabric cushions. There’s a certain peace of mind that comes from knowing exactly what you’re using on the surfaces your family touches every day.

While commercial products may still have their place in extreme cases, for the average mold problem on carpets, this DIY method is more than enough.
