Nothing ruins the feeling of opening a clean, organized closet quite like a wave of musty odor hitting your nose. You know the smell. It’s that stale, damp scent that makes your clothes feel less fresh, even after you just washed them.
I’ve dealt with this problem more than once, especially in older homes and closets that didn’t get much airflow. The good news? You don’t need harsh chemicals or expensive products to fix it. In fact, some of the most effective solutions come from simple household items you probably already have.
So, how do you get rid of musty smell in a closet naturally? Let’s break it down step by step.
Why Does a Closet Smell Musty?
Before you tackle the odor, you need to understand what causes it.
A musty smell usually appears when moisture, poor ventilation, and trapped air work together. Closets often stay closed for long periods, creating the perfect environment for odors to linger.
Common causes include:
Excess humidity
Damp clothing
Poor airflow
Mold or mildew growth
Storing shoes before they dry completely
Water leaks nearby
Ever notice how the smell gets stronger after rainy weather? That’s usually a humidity issue waving hello.
Empty the Closet First
I know this sounds obvious, but many people skip this step and wonder why the smell keeps coming back.
Remove everything from the closet, including:
Clothes
Shoes
Storage bins
Blankets
Accessories
Once the closet sits empty, you can inspect every corner properly.
Check for:
Damp spots
Water stains
Mold growth
Dust buildup
A quick inspection can save hours of frustration later.
Clean Every Surface Thoroughly
Musty odors often cling to shelves, walls, and floors.
Grab a bucket of warm water and add natural cleaning ingredients such as:
White vinegar
Lemon juice
Mild dish soap
I usually prefer vinegar because it neutralizes odors incredibly well. Sure, vinegar smells strong at first, but that scent disappears quickly.
Wipe down:
Shelves
Baseboards
Closet rods
Doors
Corners
Pay special attention to hidden areas where dust likes to throw secret parties.
Use Vinegar for Odor Removal
White vinegar works as a natural deodorizer.
Mix:
1 cup white vinegar
1 cup warm water
Spray the solution lightly onto hard surfaces and wipe clean.
Vinegar helps eliminate odor-causing bacteria and mildew naturally.
Let Fresh Air Do the Heavy Lifting
Fresh air works wonders.
After cleaning, leave the closet doors open for several hours. If possible, open nearby windows as well.
Air circulation helps:
Remove trapped odors
Reduce moisture
Speed up drying
Sometimes I place a fan near the closet entrance. It’s a simple trick, but it makes a noticeable difference.
Why spend money on fancy odor removers when moving air can solve half the problem?
Absorb Moisture with Natural Remedies
Moisture often causes the musty smell in the first place. Remove the moisture, and you remove the odor source.
Baking Soda
Baking soda remains one of the best natural odor absorbers available.
Place an open container of baking soda inside the closet.
You can also sprinkle baking soda on carpeted closet floors before vacuuming.
Benefits include:
Absorbs odors
Reduces moisture
Inexpensive
Safe around clothing
FYI, I keep a small bowl of baking soda in several storage areas year-round.
Activated Charcoal
Activated charcoal acts like a magnet for odors and moisture.
Place charcoal bags on shelves or hang them inside the closet.
Benefits:
Long-lasting
Chemical-free
Excellent odor absorption
Helps control humidity
Many people overlook charcoal because it isn’t flashy. Meanwhile, it quietly does an amazing job.
Rock Salt
Rock salt naturally attracts moisture from the air.
Place a bowl of rock salt in the closet and replace it when it becomes damp.
This old-school method still works surprisingly well.
Use Natural Deodorizers
Once you've eliminated the source of the smell, add a fresh scent naturally.
Dried Lavender
Lavender smells fantastic and helps freshen enclosed spaces.
Place dried lavender in:
Small fabric bags
Sachets
Decorative bowls
Your clothes may even pick up a subtle, pleasant fragrance.
Cedar Blocks
Cedar naturally combats odors and absorbs excess moisture.
Many homeowners use cedar because it:
Smells fresh
Repels certain insects
Lasts for years
Requires minimal maintenance
I’ve used cedar blocks in closets for years, and they consistently outperform many store-bought fresheners.
Lemon Peels
Fresh lemon peels can provide a temporary burst of freshness.
Simply place dried peels in a small dish.
Just remember to replace them regularly.
Otherwise, the solution becomes the problem. Nature has a funny sense of humor sometimes :)
Wash Musty Clothes Before Returning Them
Here’s a mistake many people make.
They clean the closet but put musty clothes right back inside.
Guess what happens next?
The odor returns almost immediately.
Wash affected clothing with:
Regular detergent
White vinegar added during the rinse cycle
Baking soda added to the wash
For stubborn odors, hang clothes outdoors to dry in fresh air.
Sunlight and airflow can work miracles.
Prevent Future Musty Smells
Getting rid of the smell matters. Preventing it from returning matters even more.
Keep Clothes Completely Dry
Never store damp clothing.
Even slightly damp fabric can create enough moisture for odors to develop.
This includes:
Jackets
Towels
Gym clothes
Shoes
Patience saves headaches here.
Avoid Overcrowding
Closets need breathing room.
When you pack clothing too tightly, air can’t circulate properly.
Try to leave small gaps between hanging garments.
Your clothes—and your nose—will thank you.
Open the Closet Occasionally
Closets aren't vaults.
Open the doors periodically and let fresh air circulate.
Even ten minutes a few times each week can help.
Use a Dehumidifier
If humidity remains high throughout your home, consider using a dehumidifier nearby.
Signs you may need one include:
Condensation on windows
Persistent damp smells
Frequent mildew issues
Controlling humidity addresses the root cause of many closet odors.
Natural Odor-Fighting Combinations That Work
Want maximum odor-fighting power?
Combine several natural methods.
A highly effective setup includes:
Clean surfaces with vinegar.
Air out the closet thoroughly.
Add baking soda.
Place cedar blocks on shelves.
Use lavender sachets for fragrance.
This combination tackles:
Moisture
Odors
Air quality
Long-term prevention
IMO, this approach works better than most heavily scented sprays because it solves the problem instead of masking it.
Signs You Might Have a Bigger Problem
Sometimes a musty smell signals something more serious.
Watch for:
Visible mold growth
Soft drywall
Water stains
Persistent dampness
Peeling paint
If these signs appear, inspect for plumbing leaks or structural moisture issues.
Natural remedies help with odors, but they can’t fix hidden water damage.
Common Mistakes to Avoid
Many people accidentally make closet odors worse.
Avoid these mistakes:
Using strong perfumes to mask smells
Ignoring moisture sources
Storing damp shoes
Overcrowding shelves
Forgetting to clean closet surfaces
Returning musty clothes too soon
Masking odors rarely works long term.
Think of it like spraying air freshener on a dirty gym bag. The result isn’t exactly magical.
Final Thoughts
Getting rid of a musty smell in a closet naturally doesn’t require expensive products or complicated solutions. In most cases, cleaning thoroughly, improving airflow, reducing moisture, and using natural odor absorbers will solve the problem.
Start by emptying the closet, cleaning surfaces with vinegar, and letting fresh air circulate. Then add moisture-fighting helpers like baking soda, activated charcoal, or cedar blocks. Don’t forget to wash any musty clothing before putting it back.
A fresh-smelling closet feels surprisingly satisfying. Open the door, take a deep breath, and enjoy the fact that your clothes smell clean instead of like they’ve been hiding in a damp cave for six months. That’s a win in my book.
