Did you know that over 65% of people struggle with armpit stains on their shirts? Don’t let those stubborn marks ruin your favorite tops. With a few simple cleaning tips, you can tackle armpit stains effectively and restore your clothing to its former glory.

From pre-treating with vinegar to soaking in lemon juice, there are various methods to try.

Stay tuned to discover the best ways to get rid of those pesky stains and keep your shirts looking fresh and clean.

Identifying the stain

To identify armpit stains on shirts, simply examine the underarm areas for discoloration or yellowing. These stains are often caused by a combination of sweat, body oils, and deodorant residue that build up over time. When inspecting the underarm area, look for any visible marks or patches that appear darker than the rest of the fabric. The stains may vary in intensity, ranging from faint discoloration to more pronounced yellow stains.

Additionally, you may notice a lingering odor in the armpit area of the shirt, even after washing. This can be another indicator of the presence of armpit stains. If you detect a musty or sour smell coming from the underarms, it’s likely that the stains have set into the fabric.

Addressing these stains promptly is key to preventing them from becoming more stubborn and difficult to remove. By identifying the armpit stains early on, you can take the necessary steps to effectively treat and remove them, restoring your shirt to its original condition.

Pre-Treating with vinegar

Consider using a mixture of vinegar and water to pre-treat armpit stains on your shirts before washing. Vinegar is a natural cleaning agent that can help break down the compounds in sweat that cause stains. To create the pre-treatment solution, mix equal parts of white vinegar and water in a spray bottle. Spray the solution directly onto the armpit stains and let it sit for about 10-15 minutes before laundering the shirt as usual.

Vinegar is effective in neutralizing odors and dissolving the proteins in sweat that lead to yellow discoloration on clothing. Its acidic properties work to loosen the stain, making it easier to remove during the washing process. Additionally, vinegar is a gentle and eco-friendly option compared to harsh chemicals found in commercial stain removers.

After pre-treating the armpit stains with vinegar, check the care label on your shirt to ensure it can withstand the washing machine. Then, wash the garment using your regular detergent and the appropriate water temperature. Repeat the pre-treatment if necessary before drying the shirt.

Scrubbing with baking soda

If vinegar alone doesn’t fully remove the armpit stains, try scrubbing the affected area with baking soda to further lift and eliminate the residue. Baking soda is a versatile cleaning agent known for its ability to absorb odors and lift stains. To use baking soda for armpit stains, mix it with a small amount of water to create a paste. Apply this paste directly to the stained areas on the shirt.

Gently scrub the baking soda paste into the fabric using a brush or your fingers. The mild abrasive nature of baking soda helps to break down the proteins and oils in the stains, making it easier to lift them from the fabric fibers. Allow the baking soda paste to sit on the shirt for about 30 minutes before rinsing it off with cold water.

After rinsing, check to see if the armpit stains have lightened or disappeared. If necessary, repeat the process or try combining baking soda with vinegar for a more potent cleaning solution.

Soaking in lemon juice

For a natural and effective way to tackle stubborn armpit stains, consider soaking your shirts in lemon juice. Lemon juice acts as a natural bleaching agent that can help break down the sweat and deodorant residues causing the stains.

To use this method, mix equal parts lemon juice and water in a bowl or container. Submerge the affected area of the shirt in the solution and let it soak for about 30 minutes to an hour. The acidity of the lemon juice helps to lift the stains while also leaving your shirts smelling fresh.

After soaking, rinse the shirt with cold water to remove the lemon juice mixture. It’s important to wash the garment immediately after soaking to prevent any potential damage to the fabric. Once washed, air dry the shirt to ensure that the stain has been fully removed before putting it in the dryer.

Washing with Oxygen-Based bleach

To effectively remove tough armpit stains from your shirts, try washing them with oxygen-based bleach. Oxygen-based bleach, like OxiClean or Clorox Oxi Magic, is a powerful stain remover that can break down and lift stubborn armpit stains effectively.

Start by filling a sink or bucket with water and adding the recommended amount of oxygen-based bleach according to the product instructions. Make sure the water is warm but not too hot, as high temperatures can set the stains rather than remove them.

Next, submerge the stained shirts in the oxygen bleach solution and let them soak for at least an hour, or overnight for tougher stains. The oxygen bleach will work to break apart the sweat and deodorant residue that causes the yellowing under your arms.

After soaking, rinse the shirts thoroughly with cold water and wash them as usual in the washing machine. Remember to check the care label on your shirts to ensure they’re safe for this type of treatment. With this method, your shirts should come out looking clean and fresh, free from those pesky armpit stains.


Say goodbye to those stubborn armpit stains with these effective cleaning tips! By pre-treating with vinegar, scrubbing with baking soda, soaking in lemon juice, and washing with oxygen-based bleach, you can easily remove those pesky stains from your shirts.
