To use these women's t-shirts, just put them on and enjoy their comfort. When it's time to clean them, machine wash them cold inside out with clothes of similar colors. Only use non - chlorine bleach if necessary. After washing, it's best to hang them dry, but you can also tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, avoid ironing and dry cleaning these shirts to keep them in good condition.
