To use these men's t-shirts, simply put them on and enjoy the comfort. When it's time to wash, remember to turn them inside out and wash in cold water with similar colors. Only use non - chlorine bleach if there are stains. After washing, you can either hang them to dry for the best look or tumble dry on a cool or low - heat setting. But be careful, fabric softener can make the colors fade. Also, don't iron or dry clean these shirts to keep them in good condition.
