3 Easy Ways To Get The Sweat Smell Out Of Shirts And Gym Clothes

3 EASY ways to get the sweat smell out of shirts and gym clothes using 2 natural ingredients or 1 of my favorite clothes cleaning products!

How To Get The Sweat Smell Out Of Shirts And Gym Clothes

If you exercise a lot, work outside, or just live in a hot, humid area, you’ve probably noticed that some clothes smell like sweat, even after washing.

Ironically, your deodorant, detergent, and fabric softener can all trap bacteria and odors in clothes. That’s because they can each leave a little residue on the fibers. And, that residue builds up overtime.

You’ve probably noticed deodorant residue in the armpit area on shirts and gym clothes.

But, don’t worry, it’s pretty easy to get rid of that built-up residue that traps body odor and sweat smell in gym cloths, shirts, and other clothes.

Let’s get to the 3 ways to get the sweat smell out of gym clothes and shirts! Then I’ll follow that up with some answers to common questions and laundry tips.

Check the label on your clothes for washing instructions before following the directions in this post.

1. How To Use Vinegar To Get Smells Out Of Clothes

You can use distilled white vinegar to get the sweat smell out of shirts and gym clothes. Distilled white vinegar is the vinegar that you usually find in the baked goods section in every grocery store.

To remove odor from clothes with vinegar, add 2 cups of white vinegar to 1/2 a gallon of tap water in a large bowl, sink, or bucket.

Use normal white vinegar mixed with water as a pre-wash soak.

Then submerge your stinky clothes in the vinegar mixture. And, leave them to soak for 3 hours or longer. I recommend leaving your clothes in the pretreat overnight.

The longer it’s in the mix, the better it works. Then wash and dry your clothes as usual.

My Vinegar Pretreat Test Results

I tested 2 shirts with a body odor smell in a weaker vinegar mix. I used just 1 cup of vinegar with 1/2 a gallon on tap water. Then, I let 2 shirts with body odor soak in the vinegar mix overnight.

After washing and drying as usual, one shirt was completely odor free after washing and drying. But the other shirt still had a very faint body odor smell in the armpits.

Scrubbing pit stains in a shirt before washing.
When a shirt has a lot of residue, I scrub the armpit fabric together to remove most of it before soaking. You can also use a soft bristle toothbrush to gently scrub off the residue before soaking your armpit stains. This works with all 3 pretreats.

So, since there was a HUGE IMPROVEMENT with the vinegar, I decided that doubling the amount of vinegar used would have completely gotten rid of the sweat smell in shirts and other clothes.

Instead of just 1 cup of vinegar (like I used), I recommend using 2 cups of vinegar with water as a laundry pretreat for clothes that smell bad.

2. How To Use Baking Soda To Get The Smell Out Of Clothes

You can pretreat clothes with sweat smells in a mixture of 1 cup of baking soda and 1/2 a gallon of tap water. Be sure to stir the baking soda until it fully dissolves before adding the clothes.

1 cup of baking soda mixed into 1/2 a gallon of water is a great prewash treatment for body odors in clothes.

Then, let your smelly clothes soak for at least 3 hours. But, again, letting them soak overnight will give the best results.

After soaking the stinky clothes in baking soda and water, wash and dry them as you normally would.

I tested this baking soda laundry pretreat on 2 of my shirts with sweat smells. And, I was honestly surprised that it completely removed the body odors.

To make this pretreat for bad smelling clothes, add 1 full scoop of OxiClean Odor Blasters to 1/2 a gallon of tap water. Then stir the OxiClean into the water to dissolve it as much as possible.

Add your smelly clothes to the OxiClean mixture, then let them soak for 3 hours or longer. The longer they soak, the better it works. I soaked mine overnight.

After soaking, wash and dry your clothes as normal. As soon as my clothes came out of the dryer, I gave them the smell test.

The heat from the dryer would have brought out any bad body odors and sweat smells. BUT, the shirts that soaked in the OxiClean mix smelled fantastic straight from the dryer!!

And, I used this on the worst of my 6 stinky shirts. Then, I wore that shirt all day yesterday. I’m happy to say that I smelled ZERO body odor or sweat smell coming off the shirt. Even when I worked out.

Why Does My Shirt Still Smell Like Sweat After Washing It?

If your shirt still smells like sweat after washing it, you might have odor-trapping residue from deodorant, too much detergent, or fabric softener in your clothes.

You can use laundry pretreats like vinegar, baking soda, or OxiClean to breakdown that residue, remove deodorant stains, and destroy bacteria and odors in the fibers.

Check out the directions above to see how to make these body odor pretreats for laundry.

Make sure to get every bit of your clothing wet before leaving it in the bowl to soak. To soak a lot of clothes, you can use a sink, just double or triple your mix, as needed. See more of my cat in 6 Ways To Hide A Kitty Litter Box in a Cabinet.

Can You Skip Fabric Softener?

You do not need to use fabric softener in the washing machine. I never do. Fabric Softener leaves a residue on your clothes that can trap in body odors and sweat smells.

Use a wool dryer ball to prevent static cling and wrinkles instead.

And, even though liquid fabric softener might make your towels and clothes feel softer, it can also reduce the normal fluffiness and absorption in towels.

The best way to get soft feeling, fluffy, absorbent towels is by washing them in the recommended amount of laundry detergent (too much detergent can leave residue too).

Then, once every couple of months, soak your towels in a sink full of water and 2 cups of vinegar for 3 hours or longer.

That vinegar soak will strip the built-up detergent and fabric softener from the towels so that they can fluff up again.

What Happens If You Use Vinegar And Laundry Detergent Together?

Mixing vinegar with laundry detergent will change the pH of the laundry detergent. Which can reduce it’s ability to clean your clothes.

Tide detergent has detailed info about how using vinegar or baking soda in the washing machine can negatively effect your clothes.

So, I would rarely use vinegar in your washing machine. Instead, you can pretreat your laundry in a sink with a vinegar or baking soda and water mix to remove residues, smoke smells, and laundry odors.
