To use these men's T-shirts and premium T-shirts, simply put them on and enjoy their comfort. When it's time to clean them, machine wash cold inside out with clothes of similar colors. If there are stains, you can use non - chlorine bleach. After washing, it's best to hang them to dry. But if you're in a hurry, you can tumble dry on cool or low heat. Remember, don't use fabric softener as it might make the colors fade. Also, stay away from ironing and dry cleaning to keep the shirts in good condition.
