To use these women's running shirts, simply put them on for your runs or workouts. When it's time to clean them, throw them in the washing machine on a cold cycle, and make sure to turn them inside out and wash with similar colors. Only use non - chlorine bleach if there are stubborn stains. After washing, you can either hang them to dry for the best look or use the cool or low - heat setting on your dryer. Remember, fabric softener can make the colors fade, so skip it. Also, don't try to iron or dry clean these shirts, as it can damage the fabric.
