There’s nothing worse than walking into your home and being hit by a musty smell from carpet. It makes your entire space feel damp, dirty, and unhealthy. Even after vacuuming or using air fresheners, the odor may still linger — and that’s usually a sign of something deeper.
Whether it’s due to water damage, pet accidents, or high humidity in Santa Maria, CA, this blog will guide you through 7 proven ways to eliminate musty carpet smells, plus when to call in the pros.
What Causes a Musty Smell from Carpet?
The musty smell from carpet often stems from one root cause: moisture.
Some common triggers include:
- Water damage from leaks or floods
- Pet urine that’s soaked deep into the fibers
- Spills that weren’t dried thoroughly
- High indoor humidity causing mold or mildew
- Old carpet padding holding on to moisture
When moisture gets trapped, it becomes a breeding ground for mold, bacteria, and mildew—resulting in that telltale musty scent.
1. Identify the Source of Moisture
Before you treat the smell, figure out what’s causing it. Is there a leak under the floor? Is your HVAC system failing to dehumidify? Solving the root of the issue is the first step.
If you live in coastal areas like Santa Maria, the marine climate can contribute to higher humidity levels indoors, making it easier for your carpet to trap moisture.
2. Deep Vacuuming
Start with a strong vacuum session — ideally using a HEPA vacuum. This helps:
- Remove mold spores
- Lift trapped dirt
- Improve air circulation through the fibers
Vacuuming alone won’t eliminate the musty smell from carpet, but it lays the groundwork for deeper treatments.
3. Use Baking Soda for Absorption
Sprinkle baking soda generously over the affected area and let it sit overnight. Baking soda is a natural deodorizer and moisture absorber.
Instructions:
- Vacuum the carpet first
- Sprinkle a thick layer of baking soda
- Leave it for 12-24 hours
- Vacuum thoroughly again
This is one of the most affordable DIY remedies that works in mild cases.
4. Vinegar + Water Spray Solution
Mix equal parts white vinegar and water in a spray bottle and lightly mist the carpet.
Vinegar:
- Neutralizes odors
- Has antibacterial properties
- Helps kill mildew spores
Warning: Do a spot test first to ensure it won’t discolor your carpet. Avoid soaking the carpet — moisture control is key.
5. Steam Cleaning
A steam cleaner penetrates deep into the fibers, loosening dirt and killing bacteria or mold that may cause the musty smell from carpet.
If you don’t own a steam cleaner, they are available for rent at many home improvement stores in Santa Maria. Make sure to dry the carpet thoroughly after steaming.
6. Use a Carpet Shampooer with Enzymatic Cleaner
Enzyme-based carpet cleaners break down organic material like pet urine or food spills, which are common causes of lingering odors.
Look for enzyme formulas that specifically target musty or mildew smells.

The Danger of Ignoring a Musty Smell from Carpet
A persistent musty smell from carpet could mean there’s hidden mold or mildew growth under the surface. This can affect:
- Indoor air quality
- Health (respiratory issues, allergies)
- Property value
- Structural damage to subflooring
Don’t wait until it turns into a bigger issue. Odor is often the first warning sign of a larger moisture or contamination problem.
FAQs About Musty Smell from Carpet
Q1: How long does it take to remove the musty smell from carpet?
Depending on the severity, it can take anywhere from a few hours (with baking soda) to a few days with professional treatment.
Q2: Can a dehumidifier help eliminate carpet odors?
Yes! A dehumidifier reduces the moisture in the air, helping prevent the musty smell from carpet from returning.
Q3: Should I replace the carpet if the smell persists?
If odors return after cleaning, the padding or subfloor might be damaged. A professional can inspect whether replacement is necessary.
Q4: Are musty carpet smells dangerous?
Prolonged exposure can lead to mold-related health issues. It’s not just an odor—it’s often a sign of indoor contamination.
Q5: Can I use essential oils to mask the smell?
You can, but it’s a temporary fix. Odor masking doesn’t solve the root cause like moisture or bacteria.
