Does Baking Soda on Carpet Really Remove Odor?

January 18, 2025

Does your carpet have a stubborn smell that just won’t go away? Whether it’s from pets, food spills, or everyday life, lingering odors can make your home feel less inviting. You’ve probably heard that using baking soda on carpet is a quick and easy way to tackle those smells — but does it actually work?

Let’s break down the science behind this popular DIY trick, how to use it effectively, and when it’s time to bring in the professionals. 

How Does Baking Soda on Carpet Fix Odor?

Baking soda, or sodium bicarbonate, is a natural compound renowned for its ability to neutralize odors. It works by absorbing both acidic and basic molecules, effectively trapping and neutralizing them at the source. This makes baking soda particularly effective for carpets, which can harbor odor-causing particles like dirt, moisture, and bacteria within their fibers. Unlike air fresheners that only mask smells, baking soda tackles the problem at its root.

How to Use Baking Soda on Carpet

Baking soda on carpet is a tried-and-true method for neutralizing odors, and it’s a favorite among DIYers for good reason. It’s affordable, eco-friendly, and safe for both pets and kids. Whether you’re dealing with pet smells, food spills, or just everyday odors, this simple household staple can make a big difference.

Before diving in, it’s important to use it correctly to ensure the best results and avoid any residue buildup. Here’s how to get your carpets smelling fresh again using baking soda:

Note: Baking soda may not be suitable for delicate carpets like wool or antique rugs. Always test in a small, hidden area first.

1. Test a Small Area First: Before jumping in, test baking soda on an inconspicuous spot of your carpet. This ensures it won’t cause discoloration or damage to the fibers, especially on delicate or antique carpets.
2. Prepare the Carpet: Start by vacuuming the entire carpet thoroughly to remove loose debris, pet hair, and dust. A clean surface helps baking soda work more effectively by allowing it to reach the source of the odor.
3. Apply Baking Soda Generously: Sprinkle a generous, even layer of baking soda over the smelly areas of the carpet. For larger spaces, work in sections to ensure good coverage. For an extra freshness boost, you can mix a few drops of your favorite essential oil into the baking soda before applying.
4. Let It Work Its Magic: Allow the baking soda to sit undisturbed for several hours — or better yet, overnight. This gives it enough time to absorb odors and neutralize any unpleasant smells trapped in the carpet fibers.
5. Vacuum Thoroughly: Once the baking soda has done its job, vacuum the carpet slowly and thoroughly. Go over the area a couple of times to ensure all the powder is removed. If the odor persists, repeat the process as needed.

When to Use Baking Soda on Carpet

Baking soda is an excellent go-to for tackling surface-level odors and keeping your carpets feeling fresh. It’s a simple, affordable option for minor issues, such as:

• Pet Smells: Light odors from fur, dander, or that unmistakable “wet dog” smell.
• Food Spills: Lingering smells from crumbs, coffee, or snack mishaps.
• Everyday Odors: Refreshing musty carpets in high-traffic areas like hallways and living rooms.

While baking soda is a great quick fix, it does have its limits. For deep-seated odors, such as:

• Mold or Mildew: Caused by excess moisture or water damage.
• Pet Accidents: Stains or smells that have soaked into the carpet padding.
• Old, Stubborn Stains: Lingering odors that have settled deep within the fibers over time.

In these cases, you’ll need a more powerful solution. Deep odors often indicate underlying issues like bacteria, moisture, or embedded debris that baking soda simply can’t reach. For long-lasting results and a truly fresh-smelling home, professional carpet cleaning is the best option.

When baking soda isn’t enough, let Floor Pro tackle those deep-seated odors with professional carpet cleaning services that leave your home smelling fresh and looking its best. Schedule your appointment today!

Pros and Cons of Using Baking Soda

Baking soda on carpet is a simple, DIY method for neutralizing light odors. However, like any solution, it has its strengths and limitations:

Pros:

• Affordable and accessible.
• Non-toxic and safe for families and pets.
• Easy to use for minor carpet odors.

Cons:

• Messy application that may require repeated vacuuming.
• Limited effectiveness for deep or persistent smells.
• Can leave behind a residue if not thoroughly removed.

While baking soda is a great tool for everyday maintenance, it’s not designed for serious carpet issues. Professional cleaning services, on the other hand, go beyond surface fixes to remove deep-seated dirt, odors, and bacteria, giving your carpets a fresh start.

Baking Soda vs. Professional Carpet Cleaning

While baking soda on carpet can be a helpful temporary fix for minor odors, it’s not a total solution. For smells that linger deep within carpet fibers or padding, professional carpet cleaning is the only way to achieve long-lasting freshness.

Here’s why:

1. Baking Soda as a Quick Fix: Baking soda works well on surface-level odors, such as light pet smells or everyday use. However, it doesn’t have the power to penetrate deep into carpet layers to tackle moisture-related smells, bacteria, or allergens.
2. Professional Cleaning for Long-Term Results: Expert cleaning services, like those offered by Floor Pro, use industrial-grade equipment to extract dirt, allergens, and odors that baking soda simply can’t reach. Professional techniques ensure your carpets are not just fresh but also hygienic and safe for your family.

While baking soda can neutralize light odors, professional carpet cleaning goes deeper. At Floor Pro, we use advanced techniques like hot water extraction to eliminate odors, bacteria, and allergens from even the thickest carpets.

Why settle for surface solutions? Contact Floor Pro today for a professional carpet deodorization service that eliminates even the most stubborn odors, leaving your home refreshed and inviting.

DIY methods like baking soda can be great for routine maintenance, but for deeply embedded odors, stubborn stains, or widespread damage, professional carpet cleaning is the best solution.
