To use these t-shirts, simply put them on and enjoy their comfort. When it's time to wash, remember to turn them inside out and use cold water. Wash them with similar colors to prevent any color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, you can either hang them to dry for the best results or tumble dry on a cool or low - heat setting. Just keep in mind that fabric softener can make the colors fade, so it's best to avoid it. And don't try to iron or dry clean these shirts, as it might damage the fabric. That way, your t - shirts will stay in great condition for a long time.
