How To Remove Body Odors From Clothes (7 Methods)

You washed it. You dried it. You folded it. Yet, when you pull that shirt on, it still smells like a locker room. We have all been there.

Body odor lingering in laundry is a common frustration, but regular detergent often isn’t enough to break down the oily bacteria that causes the stink. After years of testing laundry hacks, we have mastered seven methods on how to remove body odors from clothes effectively.

Key Takeaways

• Vinegar soak: Pre-soak clothes in a 1:4 solution of distilled white vinegar and water for 30 minutes to break down bacteria.
• Baking soda boost: Add a cup of baking soda to your wash cycle or create a paste for targeted odor removal.
• Enzymes are key: Use enzyme-based detergents for biological fluids like sweat, urine, and vomit.
• Sunlight helps: UV rays are a natural disinfectant, so line dry your clothes whenever possible.

How to Remove Body Odors from Clothes

Standard detergent lifts dirt, but it sometimes traps odors. We will share seven methods to strip the buildup and bring your clothes back to ultimate freshness.

Distilled White Vinegar

Vinegar is the holy grail of odor removal. The acid cuts through the mineral and bacteria buildup that detergent leaves behind. We use this with almost every load of laundry to keep things crisp.

1. Air it out: Never throw damp, sweaty clothes directly into the hamper. Let them dry completely first to prevent mold and bacteria growth.
2. Soak it: Mix one part distilled white vinegar with four parts cold water. Submerge the clothes for 30 minutes.
3. Wash: Run the cycle as normal.
4. Check the smell: Do not dry the item until the smell is gone. Heat will lock the odor in permanently.
5. Repeat: If it still stinks, soak it again.

Top Tip

For gym socks, pre-soak them in this vinegar solution every time. Even if you didn’t do a heavy workout, socks trap a high volume of bacteria.

Baking Soda

Baking soda works differently than vinegar. While vinegar is acidic, baking soda is alkaline. This makes it excellent for neutralizing acidic odors like sweat and urine.

1. Prepare the soak: Fill a sink or bucket with warm water.
2. Dissolve: Add one cup of baking soda and stir until dissolved.
3. Soak: Submerge the garments and let them sit overnight. This dwell time is crucial for deep odors.
4. Wash: In the morning, wash with a heavy-duty, unscented laundry detergent. Avoid heavy fragrances that just mask the problem.
5. Dry: Once the odor is gone, dry according to the care label.

Bonus Tip

For localized smells (like armpits), mix baking soda and a little water to make a thick paste. Rub it into the fabric, let it sit overnight, and wash as normal.

Enzyme Detergents (For Organic Stains)

Sometimes home remedies aren’t enough. If you are dealing with vomit, poop, or severe sweat, you need enzymes. Protease enzymes specifically break down protein-based stains that cause smells.

1. Remove residue: Scrape off any solids first. Wear gloves to protect your hands and hygiene.
2. Cold rinse: Rinse the spot with cold water. Hot water can “cook” proteins into the fibers, setting the stain forever.
3. Pre-treat: Apply an enzyme-based stain remover or heavy-duty detergent directly to the spot. Let it sit for 15 minutes.
4. Wash hot: Once the stain is treated, wash on the hottest setting the fabric care label allows to kill the bacteria.

Try This

Look for detergents labeled “Sports” or “Active Wear.” These are formulated specifically to pull oils out of synthetic fabrics like polyester.

Lemon Juice

If you prefer a fresh, natural scent, lemon juice is a solid eco-friendly option. The citric acid breaks down oils, and it smells much better than vinegar (1).

1. Squeeze: Juice several lemons.
2. Mix: Combine the juice with two liters of warm water.
3. Soak: Let the clothes sit in the solution for 30 to 60 minutes.
4. Wash: Rinse with cool water and run a normal wash cycle.
5. Sun dry: Hang outside. The combination of lemon residue and sunlight acts as a natural bleacher.

Keep In Mind

Lemon juice acts as a mild bleach. Do not use this method on dark colors or black clothing, or you might end up with tie-dye accidents (2).

Washing Soda

Washing soda (sodium carbonate) is baking soda’s stronger, grittier cousin. It is highly alkaline and acts as a solvent to remove a wide range of stains. It is perfect for gym clothes that have that stubborn, “perma-stink.”

Safety Note: Washing soda is a skin irritant. Always wear rubber gloves when handling it (3).

1. Sprinkle: Cover the smelly areas with washing soda. You might use up to 1/4 cup for large areas.
2. Scrub: Spray lightly with water to form a paste and scrub it into the fibers using your gloved hands.
3. Wait: Let it sit for 30 minutes.
4. Launder: Wash the garment as normal to rinse away the soda and the smell.

Aspirin and Cream of Tartar

This sounds like a science fair project, but the chemistry checks out. Cream of tartar creates an acidic environment (4), and aspirin contains salicylic acid, which attacks sweat stains (5).

1. Crush: Crush three non-coated aspirin pills into a cup of warm water.
2. Mix: Add one tablespoon of cream of tartar.
3. Scrub: Use an old toothbrush to work the paste into the armpits or collar.
4. Rest: Leave it for 20 minutes.
5. Wash: Launder as usual.

Salt

If you are out of everything else, check the pantry for table salt. Salt dehydrates bacteria and can help pull moisture out of the fabric (6).

1. Dissolve: Pour 1/2 cup of salt into a bowl of warm water. Stir until clear.
2. Soak: Add the smelly clothes and let them soak for a few hours.
3. Wash: Rinse and wash normally.

How to Remove Body Odor from Clothes Without Washing

Sometimes you need to refresh a blazer or a pair of jeans without running a full load. Here is how to kill the bacteria without a washing machine.

The Vinegar Spray

This is great for neutralizing odors on the fly.

1. Mix: Combine equal parts distilled white vinegar and water in a spray bottle.
2. Scent (Optional): Add a few drops of essential oils. Thyme, oregano, and rosemary have antibacterial properties (7), but lemon or eucalyptus smell fresher.
3. Spray: Turn the garment inside out and spray the smelly areas liberally.
4. Dry: Hang it in a well-ventilated area. The vinegar smell will vanish as it dries.

The Vodka Trick

Theater costumers have used this trick for decades because you cannot wash delicate costumes daily.

1. Pour: Put cheap, high-proof vodka into a spray bottle. Do not dilute it.
2. Spray: Mist the clothes. The high alcohol content kills bacteria on contact.
3. Evaporate: As the alcohol evaporates, it takes the odor with it, leaving no scent behind.

What Causes Body Odors?

To fix the problem, you have to understand the source. Sweat itself is actually odorless. The smell comes from bacteria on your skin breaking down the sweat.

This process happens most near the apocrine glands (8). You will find these in high-friction areas like armpits and the groin. Unlike regular sweat glands that cool you down, these glands produce a milky fluid that bacteria love to eat.

Foot odor is similar but exacerbated by shoes. Socks trap moisture, creating a dark, damp incubator for bacteria and fungi.

Other culprits include residue from cooking, smoke, mildew from damp towels, and even gasoline.

Why Do My Clothes Smell of BO After Washing Them?

You open the washer expecting an ocean breeze scent, but you get hit with wet dog or locker room smell. Why?

Here are the three most common reasons:

• Sebum Buildup: Sebum is a sticky, waxy body oil. It embeds itself deep into synthetic fibers like polyester. If you wash in cold water with a weak detergent, the oil (and the smell) stays right where it is (9).
• Too Much Detergent: It sounds counterintuitive, but more soap is not better. Excess suds cushion the clothes so they don’t rub against each other to get clean. The extra soap also traps bacteria in the fabric.
• Dirty Machine: If your washer has mold in the gasket or residue in the drum, you are essentially washing your clothes in dirty water.

How to Prevent Body Odors

Stopping the smell before it starts is easier than scrubbing it out later.

• Wash Inside Out: The sweat and bacteria are on the inside of your clothes. Turning them inside out exposes the dirty surface to the water and detergent.
• Don’t Let it Sit: Bacteria multiply rapidly in damp environments. If you leave sweaty gym clothes in a hamper for three days, the smell will be much harder to remove.
• Wear Deodorant: Apply antiperspirant at night and in the morning. It blocks the sweat ducts, reducing the “food” available for bacteria.
• Shave High-Odor Areas: Hair provides more surface area for bacteria to cling to. Shaving armpits can significantly reduce odor retention (10).
• Diet Adjustments: Foods like garlic, onions, and heavy red meat consumption can alter your body chemistry and make your sweat smell stronger (11).

FAQs

How Does Baking Soda Get Rid of Body Odor In Clothes?

Baking soda (sodium bicarbonate) is alkaline. Most body odors, including sweat and urine, are acidic. The baking soda reacts with the acid to neutralize the pH, effectively canceling out the smell rather than just covering it up.

Can I Soak Clothes In Vinegar Overnight?

Yes, you can soak clothes in vinegar overnight safely. However, a 30-minute soak is usually sufficient for odors. If you soak for longer, ensure the vinegar is diluted with water to protect delicate fibers.

Will Vinegar Damage Clothes?

Vinegar is generally safe for fabrics, but it is acidic. Do not use it on natural stone (like in a bathroom while hand washing) and avoid mixing it with bleach, as this creates dangerous fumes. It can also degrade rubber seals in washing machines if used excessively.

Why Can’t You Smell Your Own Body Odor?

This is called olfactory adaptation or “nose blindness.” Your brain filters out constant background scents to focus on new changes in your environment. Unfortunately, this means you are often the last person to notice you smell.

What Foods Make Body Odor Worse?

Sulfur-rich foods like broccoli, cauliflower, and cabbage can alter body odor. Additionally, garlic, onions, spices like curry and cumin, and alcohol can seep out through your pores, making your sweat smell pungent.

Why Do My Gym Clothes Smell Worse Than My Regular Clothes?

Gym clothes are often made of synthetic fabrics like polyester and spandex. These are lipophilic, meaning they love oil. They soak up body oils and sebum, trapping them deep in the fibers where water and regular detergent struggle to reach.

Chase Freshness

We are all familiar with that stubborn funk clinging to our favorite shirts. While it is annoying, it isn’t permanent if you use the right chemistry.

Start with a simple vinegar soak or a baking soda wash. These pantry staples solve 90% of odor issues. For the really tough stuff, do not be afraid to reach for enzyme cleaners.

Stay on top of your hygiene, keep your machine clean, and stop letting those sweaty socks sit in the hamper for a week. Your nose (and your friends) will thank you.
