A musty-smelling carpet is more than just an unpleasant nuisance—it can make your entire home feel uninvited and even signal a problem like mould or mildew. Whether the smell resulted from a spill, pet accident, or damp conditions, you don’t have to live with it forever. You can restore your carpet’s freshness and keep it smelling great with the right approach.
This blog post will walk you through actionable steps to eliminate musty carpet odours for good. From DIY solutions to when to call a pro, you’ll have the tools to reclaim your carpet and refresh your home.
Why Does My Carpet Smell Musty?
Before jumping into solutions, it’s essential to understand the source of the problem. A musty smell in your carpet is often caused by:
- Moisture: Spills, leaks, or high humidity can leave moisture trapped in your carpet fibres, padding, or floorboards underneath.
- Mould and Mildew: Trapped moisture can lead to mould or mildew growth, contributing to that damp, earthy smell.
- Pet Accidents: Even if cleaned, pet urine can leave behind lingering odours that develop a musty aroma.
- Poor Ventilation: Limited airflow can exacerbate smells by preventing moisture from evaporating.
- Extended Carpet Wear: Over time, carpets can trap dirt, oils, and other substances that build up unpleasant odours.
The good news? With the proper techniques, these issues are manageable.
Step-by-Step Guide to Remove Musty Carpet Odors
Step 1: Identify and Address Moisture Sources
Start by locating the source of the problem. Carefully inspect the room for:
- Leaks from nearby pipes or windows.
- High humidity levels (often noticeable in basements).
- Pet stains or spills soaking into the carpet.
If moisture is present, dry the area immediately using towels and a fan. For continued humidity problems, consider using a dehumidifier to regulate air moisture.
Step 2: Vacuum Thoroughly
Before trying any cleaning techniques, vacuum the carpet thoroughly to remove loose dirt, dust, and debris. Use a vacuum with a HEPA filter or a beater bar for best results. This step prevents grime from mixing with your cleaning solution and creating additional odours.
OptOpt for a deep-cleaning vacuum with a carpet set to lift dust from within the fibres if possible.
Step 3: Sprinkle Baking Soda on the Carpet
Baking soda is a natural odour neutralizer that can work wonders on musty smells. Here’s how to use it:
- Generously sprinkle baking soda across the entire carpet, focusing on smelly areas.
- Use a soft-bristled brush or broom to work the baking soda into the fibres.
- Leave it overnight (or at least 6 hours) to absorb the odours.
- Vacuum thoroughly to remove the baking soda.
Repeat this process if necessary for more pungent odours.
Step 4: Use a Vinegar Solution for Spot Cleaning
Vinegar is an excellent option for areas with stubborn smells, such as pet-stained spots or spills. Its acidic properties break down odor-causing particles.
What You’ll Need:
- White vinegar
- Water
- A spray bottle
- A clean cloth or sponge
Instructions:
- Mix equal parts white vinegar and water in a spray bottle.
- Spray the solution directly onto the smelly area.
- Blot (don’t rub!) the moisture using a cloth or sponge.
- Allow the area to air dry completely.
Follow up with baking soda for an added odour-fighting boost.
Step 5: Shampoo or Use Carpet Cleaners
Commercial carpet shampoos or rental carpet cleaners are effective for deeper cleaning. Here’s how to use these tools:
Shampooing by Hand:
- Purchase a carpet shampoo designed for the type of carpet you have.
- Scrub the shampoo into the carpet using a soft-bristled brush.
- Rinse with clean water and dry thoroughly.
Using a Carpet Cleaner:
- Rent or invest in a carpet cleaner. These machines apply cleaning solutions directly to the carpet and remove it with suction.
- Follow the manufacturer’s instructions and use cleaning solutions that are compatible with your machine.
- Allow the carpet to dry thoroughly after cleaning.
Tip: Open windows or use fans to speed up drying times.
Step 6: Deodorize with Essential Oils
Looking for a natural, pleasant way to refresh your carpet? Essential oils can help.
- Add a few drops of your favourite essential oil (like lavender, eucalyptus, or lemon) to a cup of baking soda.
- Sprinkle the mixture over your carpet.
- Please wait at least an hour, then vacuum it up.

Step 7: Hire a Professional Cleaner (If Needed)
Calling a professional cleaner can save the day from lingering smells that won’t budge or if mould is suspected. Professional-grade tools and expertise can eliminate deeper issues that DIY methods can’t fully address.
How to Prevent Musty Smells in Your Carpet
Once your carpet is fresh again, keep it that way! Here are some helpful tips for maintaining odor-free carpets:
- Invest in a Dehumidifier: High humidity can cause ongoing moisture problems, especially in basements.
- Use Rugs in High-Traffic Areas: Rugs are easier to clean and protect the carpet underneath.
- Clean Spills Immediately: Blot spills with a towel to remove moisture and prevent mold growth.
- Schedule Regular Deep Cleans: Steam clean or shampoo your carpets annually or every six months for high-traffic spaces.
- Air Out the Room: Open windows and use fans to improve ventilation and keep smells at bay.
The Importance of Addressing Musty Smells Quickly
A musty-smelling carpet isn’t just unpleasant—it can impact your health. Mold and mildew growth can release spores into the air, contributing to allergies, asthma, and respiratory problems. Addressing odours ensures the health of your home while increasing comfort and cleanliness.
Final Thoughts
Eliminating a musty smell from your carpet may seem challenging, but with the right tools and techniques, you can banish those odours for good. Start with basic steps like vacuuming and baking soda, and escalate to vinegar solutions, carpet shampoos, or professional cleaning as needed.
A carpet free of odours is a win for your home, health, and enjoyment. If you’ve tried everything and still need help, don’t hesitate to seek expert cleaning services.
