How to Get Rid of Sweat Stains

Sometimes your hard work (or previous day’s makeup) shows up on your shirt. To keep sweat stains from ruining your clothes, simply prepare a soaking solution and stain removal paste, then use a toothbrush to scrub the stain and machine wash. Act as soon as you notice sweat stains building up so they don’t spread or set in further, and always check your clothing’s care label for any specific requirements like dry cleaning before treating. See the five steps below to learn how to remove old sweat stains.

What Causes Sweat Stains?

The combination of water, fats, proteins and salt in your sweat—as well as the deodorant additives like aluminum and zirconium, and body oils—all contribute to sweat stains. These molecules build up over time to ultimately embed into the fabric of clothing fibers, and may even bind to the fabric and cause the yellow discoloration often found on sweat-stained clothing. 

Does Sweat Stain Clothes Permanently?

Sweat stains don't have to be permanent, but they can become more difficult to remove if you don’t treat them quickly or follow the right process. Stains that go unnoticed or untreated can set in further with a typical heated dry cycle, so it’s best to opt for air drying as you work on removing sweat stains from clothing. If your first attempt at removing stains isn’t effective, repeat the stain removal process until you’re satisfied before you return your garment to a heated dry cycle.

Just Say No to Chlorine Bleach

You may be tempted to bleach out sweat stains, but chlorine bleach can actually make sweat stains worse by making them appear darker. If you really want to use bleach, reach for oxygenated bleach instead, which has a different chemical structure that removes protein stains easily.

Step 4: Use a Toothbrush to Scrub the Stain

Step 5: Machine Wash with Hot Water

After 20 minutes, it’s time to wash your shirt in your washing machine on the hottest water setting recommended on the care tag. Line dry the item: heat from a dryer will set any stain left behind that you can't see while the fabric is wet. If the stain remains after it dries, repeat the steps as many times as necessary.


And that’s it! You just saved your shirt in 5 easy steps. No sweat.

Consider Switching to Aluminum-Free Deodorant

Those unsightly sweat stains that discolor your shirts aren’t caused by sweat alone. When you sweat, the triple threat of aluminum in your antiperspirant mixed with the sweat and proteins on your skin causes the stain. You may want to switch to an aluminum-free antiperspirant or deodorant instead. The easiest way to remove sweat stains is to prevent them from happening.
