The body sweats as a way to regulate the body's temperature. There are sweat glands founds all over the body, including the armpits, behind the knees and the palms of the hands. Perspiration itself is generally clear and composed of salt and water. When the sweat reaches the surface, it can take on an odour because of the breakdown of the sweat caused by bacteria on the skin. It is possible to remove the odour associated with perspiration from synthetic fibres, such as polyester and nylon at home.
Fill a bucket with one gallon of cool water and one cup white vinegar
Place the garment into the bucket and allow it to soak for 12 hours, or overnight.
Remove the polyester or nylon garment from the bucket and rinse the vinegar away with water.
Place the piece into the washing machine. Add one cup washing powder and two cups baking soda to the washing machine.
Set the machine to the permanent press cycle on a warm water setting and allow the full washing cycle to run.
Remove the garment and smell it. Repeat the washing cycle with one cup of washing powder and two cups of baking soda if there is still a perspiration odour.
Place the garment into the dryer on a warm setting, if desired.
Hang the garment out to dry in the sunlight. The rays and heat from the sun will help remove any lingering odours.
