Are you tired of throwing away your favorite white shirts due to unsightly dark underarm stains? Do you struggle to get rid of these stubborn stains, no matter how hard you try? You’re not alone. Dark underarm stains on white shirts are a common problem that can be frustrating and embarrassing. But don’t worry, we’ve got you covered. In this article, we’ll explore the causes of dark underarm stains and provide you with a comprehensive guide on how to remove them from your white shirts.
What Causes Dark Underarm Stains on White Shirts?
Before we dive into the removal methods, it’s essential to understand what causes these stains in the first place. Dark underarm stains on white shirts are usually caused by a combination of factors, including:
Sweat and Bacteria
When you sweat, your body releases a protein called keratin, which can bind to the cotton fibers in your shirt. As the sweat evaporates, it leaves behind a residue that can attract bacteria. These bacteria thrive in warm, moist environments and feed on the keratin, breaking it down into compounds that can cause discoloration.
Antiperspirant and Deodorant
Antiperspirants and deodorants can also contribute to dark underarm stains. These products often contain aluminum-based compounds that can react with the sweat and bacteria on your skin, causing discoloration. Additionally, some antiperspirants and deodorants can leave behind a residue that can bind to the cotton fibers in your shirt.
Friction and Wear
Friction and wear can also cause dark underarm stains on white shirts. When you move your arms or wear tight clothing, it can cause the cotton fibers to rub against each other, leading to friction. This friction can cause the fibers to break down, leading to discoloration.

What causes dark underarm stains on white shirts?
Dark underarm stains on white shirts are usually caused by the combination of sweat and the chemicals found in antiperspirants or deodorants. When these chemicals mix with the proteins in sweat, they can cause discoloration on clothing. This discoloration can range in color from yellow to brown and can be difficult to remove.
The type of fabric the shirt is made of can also contribute to the formation of dark underarm stains. Natural fibers like cotton and linen are more prone to discoloration than synthetic fibers like polyester. Additionally, the acidity of a person’s sweat can also play a role in the formation of these stains.

To prevent dark underarm stains from forming on your white shirts, you can try using a natural antiperspirant or deodorant that doesn’t contain harsh chemicals. You can also wear a undershirt or a sweat-absorbing undershirt to absorb sweat before it reaches your outer shirt. Applying a stain-preventing spray or stick to the underarm area of your shirt can also help prevent stains from forming.
Another way to prevent dark underarm stains is to wash your shirts as soon as possible after wearing them. This can help prevent the stains from setting in and making them more difficult to remove.
