Sweating is perfectly normal and is the body's way of moderating temperature, but the smells associated with sweating can be unpleasant and embarrassing. If you've laundered your clothes and they look bright and clean but still harbor an underarm odor, it's time to try some new tactics to restore your clothing's fresh, clean smell. Launder bad-smelling garments separately so the smell won't be transferred to your other garments.

Aspirin and Cream of Tartar
A blend of aspirin and cream of tartar may be an effective treatment for stubborn underarm odor. Mix three white, noncoated aspirins in a bowl with a cup of warm water and a tbsp. of cream of tarter. Scrub the paste into the underarm area of the clothing with an old toothbrush, then allow the mixture to remain on the garment for at least 20 minutes. Launder as usual. Repeat up to three times, if necessary.
Baking soda can often neutralize odors caused by perspiration. Make a paste with baking soda and warm water, then rub the paste into the problem areas. Leave the paste on the garment for 15 minutes, or allow it to remain overnight. Launder the garment as usual.
Try a salt solution to remove unpleasant underarm odors from your clothing. Dissolve several spoonfuls of table salt in a bucket or bowl of warm water. Soak the affected garment, then launder.
Vinegar is a powerful odor neutralizer and may be just what you need get rid of stubborn smells. Fill the washing machine with water, then add 1/3 cup of vinegar. Soak the garment for at least 10 minutes, then launder as usual. If necessary, add another 1/3 cup of vinegar during the rinse cycle.
Hang just-laundered garments in fresh air and sunshine instead of placing them in the dryer. Odors can be difficult to remove after the heat of the dryer has set the odors into the garment. Don't allow colored garments to remain in bright sunshine too long, as the sun can fade clothing.
