Understanding Underarm Stains

Underarm stains on shirts are a common issue that many individuals face. These stains are caused by sweat and can be persistent and difficult to remove. Understanding the source and nature of underarm stains is crucial in effectively removing and preventing them. In this article, we will explore various methods and techniques to remove underarm stains from shirts, allowing you to maintain the quality and appearance of your clothing.

Causes of Underarm Stains

Underarm stains are primarily caused by a combination of sweat and antiperspirant or deodorant usage. When sweat mixes with these products, it creates a chemical reaction that leads to the yellow or brown stains commonly found on shirts. Other factors that contribute to underarm stains include:

  • Body chemistry
  • Fabric type and color
  • Environmental factors such as humidity

Body Chemistry

Each individual has a unique body chemistry that can influence the severity and persistence of underarm stains. Factors such as the pH level of sweat and the presence of certain bacteria contribute to the discoloration of shirts. Some individuals may naturally produce more sweat or have higher levels of bacteria, making them more prone to underarm stains.

To minimize the impact of body chemistry on underarm stains, it is essential to maintain proper hygiene by showering regularly and using antiperspirants or deodorants that suit your body chemistry. Additionally, adopting strategies to control sweating, such as wearing breathable clothing and using talcum powder, can help reduce the occurrence of underarm stains.

Fabric Type and Color

The type of fabric used in shirts can affect the appearance of underarm stains. Synthetic fabrics, such as polyester or rayon, are more prone to retaining sweat and developing stains compared to natural fibers, such as cotton or linen. Similarly, lighter-colored shirts tend to show underarm stains more prominently than darker-colored ones.

To minimize underarm stains caused by fabric type and color, opt for shirts made of natural fibers such as cotton, which are more breathable and absorbent. Additionally, choosing darker-colored shirts can help conceal underarm stains.

Environmental Factors

The environment in which you wear your shirts can also contribute to the occurrence of underarm stains. High humidity levels can increase sweat production and make it more challenging for sweat to evaporate, leading to underarm stains. Additionally, wearing tight or ill-fitting shirts can restrict airflow, exacerbating sweating and staining.

To mitigate the impact of environmental factors on underarm stains, choose clothing made of breathable materials that allow air circulation. Avoid wearing tight shirts that can trap sweat and opt for looser, more comfortable fits.

Methods to Remove Underarm Stains

Now that we understand the causes of underarm stains, let's explore some effective methods to remove them from shirts. It's important to note that the success of these methods may vary depending on the fabric type, age of the stain, and other factors. Here are some proven techniques:

  • Lemon Juice and Baking Soda
  • Hydrogen Peroxide
  • Vinegar
  • Commercial Stain Removers

Lemon Juice and Baking Soda

Lemon juice and baking soda are effective natural cleaners that can help remove underarm stains. Create a paste by mixing equal parts lemon juice and baking soda. Apply the paste to the stained area and let it sit for 30 minutes to an hour. Then, gently scrub the stained area with a soft brush or toothbrush before rinsing the shirt thoroughly. Repeat the process if necessary.

Note that lemon juice may have bleaching properties, so it's important to test the mixture on an inconspicuous area of the shirt before applying it to the stain. Avoid using this method on delicate fabrics or colored shirts, as it may cause discoloration.

If the underarm stain persists, you can try using hydrogen peroxide as an alternative method.

Hydrogen Peroxide

Hydrogen peroxide is a powerful stain remover that can effectively tackle underarm stains. Apply hydrogen peroxide directly to the stained area of the shirt and let it sit for 10-15 minutes. Then, rinse the shirt with cold water and wash it as usual. Check the fabric care label to ensure compatibility with hydrogen peroxide.

Important: Hydrogen peroxide may cause discoloration on certain fabrics, so perform a patch test on an inconspicuous area of the shirt before using it on the stain. Avoid using hydrogen peroxide on delicate fabrics or colored shirts that may be sensitive to bleaching agents.

If the stain is stubborn or you prefer an alternative method, consider using vinegar.


Vinegar is an effective natural cleaner that can remove underarm stains and neutralize odor. Mix equal parts vinegar and water and apply the solution to the stained area. Allow it to sit for approximately 30 minutes before rinsing the shirt thoroughly. Finally, wash the shirt as you normally would, ensuring the stain is completely gone before drying.

Like other methods, it's advisable to test the vinegar solution on a small, inconspicuous area of the shirt first to ensure compatibility with the fabric. Vinegar may cause discoloration on certain materials.

Commercial Stain Removers

If natural remedies do not yield satisfactory results, consider using commercial stain removers. There are numerous stain remover products available in the market, designed specifically for the removal of various types of stains, including underarm stains. Follow the instructions on the product's packaging for best results.

When using commercial stain removers, it's crucial to spot test the product on an inconspicuous area of the shirt to avoid potential damage. Refer to the fabric care label for any specific instructions or warnings.

Preventing Underarm Stains

While removing underarm stains is important, prevention is key to maintaining the quality and appearance of your shirts. Here are some tips to help prevent underarm stains:

  • Choose antiperspirants or deodorants with aluminum chloride, which can minimize sweat production.
  • Allow antiperspirants or deodorants to dry completely before dressing to prevent staining.
  • Apply antiperspirants or deodorants at least 15 minutes before putting on your shirt.
  • Wear undershirts or garment shields to absorb sweat and protect your shirts.
  • Regularly clean your shirts to remove sweat and oil buildup that can lead to stains.


Underarm stains on shirts can be a persistent nuisance, but with the right techniques and preventive measures, you can keep your shirts looking clean and fresh. By understanding the causes of underarm stains and choosing appropriate stain removal methods, you can effectively remove underarm stains and maintain the longevity of your shirts. Remember to always test any cleaning or stain removal method on a small, inconspicuous area of the shirt before applying it to the stain. With these tips, you can confidently tackle underarm stains and enjoy stain-free shirts.
