These DinoMike women's shirts are super easy to use. Just put them on and enjoy the comfort. When it's time to clean them, machine wash in cold water, turning the shirts inside out and washing with similar colors. Only use non - chlorine bleach if necessary. After washing, you can either hang them to dry for the best results or tumble dry on cool/low heat. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry clean these shirts to keep them in good shape.
