These t-shirts are super easy to use. Just put them on and enjoy your day. When it's time to clean them, machine wash them cold inside out with clothes of similar colors. If they get dirty and need bleaching, use non - chlorine bleach. After washing, hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Remember, using fabric softener might make the colors fade. And don't iron or dry clean these shirts to keep them in good shape.
