Body odor in the armpit area of clothing can be unpleasant as well as embarrassing. It is not your perspiration itself that causes an unpleasant smell, but rather the bacteria that thrive on it and break down the sweat into fatty acids. A simple method to remove armpit odor combines bacteria elimination with traditional laundering.
Things You'll Need
2 cups distilled white vinegar
1 cup baking soda
Commercial liquid detergent
2 tsp. tea tree essential oil
Place your clothes in a basin or sink with the distilled white vinegar and enough water to cover them. Vinegar, with its low pH, effectively kills most bacteria that cause body odor. Alternatively, you can substitute the vinegar with 1 cup of baking soda. Baking soda has a very high pH, which, like vinegar, effectively kills bacteria.
Allow the clothes to soak overnight, then wash as normal. Air dry the clothes on a line outside.
Apply a commercial liquid detergent directly to the armpit area of your clothing. In addition, examine your clothing carefully for any other perspiration stains that may remain and be causing a foul odor. Apply the detergent to these areas as well.
Allow the detergent to remain on the clothing for 30 minutes, then launder as normal. Air dry on a line outside.
Mix together 2 tsp. of tea tree essential oil and 2 cups of water in a spray bottle should any odor remain. Spray the area that is emitting a smell with this mixture and allow to air dry on a line outside.
Change your clothing frequently. Wearing the same clothes for more than one day increases the likelihood of them emitting the smell of body odor.
