How to Remove Sweat and Armpit Stains [Complete Guide]

Sweat stains on clothing and household items can be annoying, unsightly, and a challenge to remove.

A complex combination made up of sweat (made up of mostly water and salt), sebum (an oil substance produced by the body), harsh ingredients found in aluminum-based deodorants (which we highly recommend avoiding), toxic conventional laundry detergents, dirt, and fabrics, sweat stains require proper attention and pre-treatment to prevent them from solidifying.

Fortunately, you don’t have to do any more online searches for “how to remove sweat stains” or “how to remove armpit stains”. In this article, you’ll learn about natural and effective stain removers such as mild dish detergent (like Branch Basics), baking soda, white vinegar, and even the sun!

Let’s dive in and explore how to use Branch Basics, and other natural DIY solutions, to break down, lift, and remove sweat stains.

How to Remove Sweat Stains From Clothes 

Sweat stains on clothing occur for a variety of reasons. Yellow stains, for example, may form when aluminum-based deodorants mix with sebum, sweat, and conventional laundry detergents. But even without the use of antiperspirants and toxic chemicals, yellow stains can still form when sebum mixes with dirt particles.

To further complicate things, trace metals found in tap water can dull clothing and enhance a sweat stain. Even more, some fabrics are not sweat-proof. As a result, fabric dyes may bleed due to sweat, discoloring the garment.

Although the origins of the stain may be a mystery, removing sweat stains from clothing doesn’t have to be.

Using a pre-made concentrate like Branch Basics, or a natural DIY solution, here’s how to remove sweat stains from clothes:

Branch Basics Method

For white clothing:

  1. Spritz the sweat stain with distilled water.
  2. Treat the stain with a few drops of Concentrate.
  3. Sprinkle Oxygen Boost on top and scrub the fabric together until it gets soapy.
  4. Let it sit overnight so Branch Basics can work its magic.
  5. Wash as normal. If the stain remains, repeat the above.
  6. When the stain is removed, dry in the sun for extra stain-removing power.

For colored clothing:

  1. In a bucket of warm water, add 1 teaspoon of Concentrate and ½ scoop of Oxygen Boost.
  2. Soak the garment overnight.
  3. Wash as normal. If the stain remains, repeat the above.
  4. When the stain has lifted, dry in the sun.

DIY Method

Distilled white vinegar is the go-to hero for tackling sweat stains on clothing. It’s so versatile, that it can be used on most fabric types. 

Note: Before treating an entire stain, we recommend testing it on a small, inconspicuous area of the clothing item to ensure it doesn’t cause any damage or discoloration.

  1. In a bowl, mix equal parts distilled water and white vinegar.
  2. Dip a microfiber cloth into the solution and lightly dab the sweat stain.
  3. Gently rub the stain in a circular motion working outwards.
  4. Let sit for at least 30 minutes.
  5. Rinse the area with water.
  6. Wash as normal. If the stain is still there, repeat the above steps.
  7. Dry the garment in the sun or by a window.

If the stains remain, give baking soda a try.

  1. Create a paste with equal parts baking soda and distilled water.
  2. Spoon the paste onto the sweat stain and gently press the paste into the stain.
  3. Let sit for at least 20 to 30 minutes.
  4. Rinse the area with water, ensuring the paste is completely removed.
  5. Wash as normal.
  6. Dry the garment in the sun or by a window.

Tip: If you haven’t already, consider switching to an aluminum-free, safe deodorant. Aluminum-based deodorants are toxic to your health and can leave behind yellow stains when they interact with your sweat.

How to Remove Sweat Stains From Hats 

Just like clothing, hats can become stained from sweat, too. But simply throwing your hat in the washer isn’t the route to take*. Instead, choose to pre-treat and handwash your baseball caps, straw and beach hats.

Reach for Branch Basics Concentrate, or some baking soda, and let’s get to work. Here’s how to remove sweat stains from hats:

Branch Basics Method

  1. Spray the stained area with Branch Basics All-Purpose.
  2. Let sit for 5-10 minutes, then gently agitate with a toothbrush or microfiber cloth.
  3. For stubborn stains, sprinkle with some Oxygen Boost and wet it with All-Purpose.
  4. Agitate until soapy and let sit for a few more minutes.
  5. Rinse in warm water.
  6. If the stain has been removed, set the hat in the sun to dry.

If the stain is still there:

  1. Soak the hat in cold water and add 1 tsp. Concentrate, and a scoop of Oxygen Boost.
  2. Let sit for 15 minutes or overnight.
  3. Periodically, gently agitate the hat’s fabric to allow the solution to work through the material.
  4. Rinse in warm water and set the hat in the sun to dry.

DIY Method

  1. Mix 4 tablespoons of baking soda with ¼ cup of distilled water.
  2. Using a toothbrush, gently apply the baking soda mixture to the sweat stains.
  3. Let sit for at least 30 minutes.
  4. Rinse the hat with clean distilled water.
  5. Pat dry with a clean microfiber cloth and allow to air dry.

*Note: Before treating sweat stains, check the hat’s care tag for cleaning instructions. Do not wash a hat in the washer. The spin cycles of modern washing machines can cause irreparable damage to your hat. Keep hats in good shape and maintain their colors by hand washing.

How to Remove Sweat Stains From Sheets 

The average person sleeps at least seven hours each night[source], indicating that the average person spends quite a bit of time in bed. Because of this, sheets often fall victim to sweat stains.

The key to removing sweat stains from sheets is to tackle them sooner rather than later. Stains that have been dried, or have set for a long time are harder to remove.

To do so, use a human-safe, fragrance-free, pre-made concentrate like Branch Basics, or a safe and chemical-free DIY solution.

Here’s how to remove sweat stains from sheets:

Branch Basics Method

To treat and clean sweat-stained sheets depends on the type of material they are made from. For example:

Cotton Sheets

  2. Soak in water overnight. For extra stain-fighting power, add 1 teaspoon of Concentrate and ½ scoop of Oxygen Boost. 
  3. Wash and dry as usual.

Silk Sheets

As a rule of thumb, always pretest silk before treating stains.

  1. Wet the sweat stains with All-Purpose.
  2. Let it dwell, then gently agitate with a toothbrush until the stain lifts.
  3. Soak if needed, then wash according to the label.

Note: Do not use Oxygen Boost on Silk Sheets.

DIY Method

  1. Add ½ cup of white vinegar to a bucket of hot water and soak sweat-stained sheets for about 30 minutes to an hour.
  2. Wash and dry per the instruction label.


  1. Create a mixture of one part liquid dish soap, such as Branch Basics Concentrate, and two parts hydrogen peroxide.
  2. Rub the mixture into the stain with a microfiber cloth or a toothbrush.
  3. Let sit for 30 minutes or overnight, depending on how stubborn the stain is.
  4. Wash in a warm water wash cycle.

How to Remove Sweat Stains From a Mattress

Strip away the comforter, sheets, and mattress pad to find…sweat stains? Yes, mattresses can also fall victim to sweat while you sleep. 

In fact, the body has, on average, 2.6 million sweat glands found on almost every part of your body (excluding your lips). As you sleep, your body sweats to detox and adjust to the room’s temperature. And although sweating is natural, removing stains from a mattress can be challenging, but it isn’t impossible!

  6. Set the mattress outside in the sun, or in a well-ventilated room, to dry.
  7. Repeat as needed.

DIY Method

  1. Fill a clean spray bottle with distilled water. Spray to dampen the sweat stains. Do not saturate.

If the sweat stains are still visible, follow with some white vinegar:

  2. Use a damp microfiber cloth to dab the vinegar into the sweat stains. Let sit for 5 to 10 minutes.

How to Remove Sweat Stains Without Washing 

On the go or don’t have time to pre-treat and wash sweat stained clothes? No fear. We have a few tricks up our sleeve for how to remove sweat stains without washing.

  1. Treat the stain immediately: The key to removing any stain is to act quickly. Otherwise, the stain could set into the fabric.
