To use these women's t-shirts, just put them on and enjoy the comfort. When it's time to clean them, machine wash them cold inside out with similar colors. Only use non - chlorine bleach if necessary. After washing, you can hang them to dry for the best look, or you can tumble dry on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean these shirts to keep them in good condition.
