It's not uncommon for sweat to come in contact with a pillow while resting. When sweat or perspiration sits on the pillow fabric, it can leave an unsightly and smelly stain. Fortunately, use a few inexpensive and common household items to remove the sweat stain from the pillow. Before trying to remove the stain, read the washing instructions printed on the pillow tag. Washing machines can damage certain types of pillows such as foam and latex.
Lay the pillow on a flat surface with the sweat stains facing up.
Fill a small container with equal parts of 3 per cent hydrogen peroxide and water. Stir the contents together with a spoon.
Dip the corner of a clean sponge in the mixture and wring out excess liquid. Blot the sweat stain with the damp sponge until the stain is saturated.
Let the mixture sit on the pillow for 30 minutes. If the pillow is washable, launder it on the gentle cycle with 1/4 cup of washing powder. If the pillow is not washable, rinse the mixture off the pillow by blotting the surface with a damp cloth. Pat dry with a towel.
Cover the pillow with a pillowcase to help protect the pillow from sweat stains. If the pillow is machine washable, add 1 cup of white vinegar to the water to help remove sweat odours from the pillow.
