How to Remove Sweat Stains and Yellow Armpit Stains from Clothes

Learning how to remove sweat stains from clothes can help keep your favorite shirts looking fresh and clean. Sweat, body oils, deodorant, and detergent residue can create stubborn yellow marks around the armpits, especially on white shirts.

In this guide, we’ll explain how to remove yellow armpit stains, treat old sweat stains, clean white and colored clothes, and prevent underarm stains from coming back.

In this guide, you’ll learn how to remove yellow armpit stains, how to treat white and colored clothes, and the best ways to deal with stubborn, dried, and deodorant-related stains.

What Causes Yellow Armpit Stains on Clothes?

Yellow armpit stains are usually caused by a combination of sweat, body oils, deodorant or antiperspirant ingredients, and residue that becomes trapped in the fabric.

Sweat itself is generally not bright yellow. The discoloration can develop when sweat and skin oils interact with products applied to the underarm area and remain in the fibers over time.

Repeated washing without proper pretreatment can also allow residue to build up. This is why simply putting a stained shirt into the washing machine may not always remove the mark completely.

How to Remove Sweat Stains from Clothes

The best way to remove sweat stains depends on how old the stain is and what type of fabric you’re treating.

Before using any cleaning method, check the garment’s care label and test your chosen solution on a small, hidden area if you’re unsure about colorfastness.

Here is a simple method you can try:

Step 1: Rinse the stained area

Start by rinsing the affected area with cool or lukewarm water. Avoid immediately using very hot water because heat can make some stains more difficult to remove.

Step 2: Apply a laundry pretreatment

Apply a small amount of liquid laundry detergent directly to the sweat stain. Gently work the detergent into the fabric using your fingers or a soft laundry brush.

Allow it to sit for around 10–15 minutes.

Step 3: Wash according to the care label

Place the garment in the washing machine and select the appropriate cycle and temperature for the fabric.

Using the correct amount of detergent is important. Too much detergent can leave residue, while too little may not provide enough cleaning power.

Step 4: Check before drying

After washing, inspect the stained area before putting the garment in the dryer.

If the stain is still visible, treat it again rather than immediately applying heat. Heat from a dryer can make some remaining stains harder to remove.
