How To Clean Underarm Stains On Undershirts

If you tend to sweat a lot you may want to know how to clean underarm stains on undershirts. Even if you don't sweat a lot, aluminum from your antiperspirant will build up and cause these nasty yellow stains. Luckily, there are a few ways to clean these stains and prevent new ones from occurring.

You'll need:

• white vinegar
• water
• hydrogen peroxide
• baking soda
• oxygen cleaning powder (optional)
• laundry detergent
• toothbrush

1. To clean underarm stains on white undershirts, mix one part water, one part hydrogen peroxide, and one part baking soda. Apply the mixture to the stains and allow it to sit for 30 minutes. The longer it sits, the better it will work. If you don't have those ingredients, you can use oxygen cleaner mixed with water to form a thin paste. Use a toothbrush to gently work the mixture into the stains.
2. Wash the undershirt in cold water as usual, with detergent. Don't use the high heat setting, as it may cause the stains to set. Even better, you can air dry it or dry it in the sun.
3. If the undershirt is colored, you may want to try using vinegar. Wash the shirt as usual in the washing machine, but add one cup of white vinegar. You can try the above steps, but you may want to test the fabric in an inconspicuous spot for lightening. Dry on low heat or air dry the shirt.

To prevent underarm stains on undershirts from forming, choose an antiperspirant with low aluminum content. If you sweat a lot while wearing the garment, wash it soon after wearing to prevent the stains from setting in. Only apply a thin layer of deodorant or antiperspirant and allow it to dry before getting dressed.
