To use this sweatshirt, simply put it on and enjoy its comfort. When it's time to clean, machine wash it cold and turn it inside out. Wash it with similar colors to avoid color bleeding. Only use non - chlorine bleach if necessary. After washing, it's best to hang it dry. But if you're in a hurry, you can tumble dry it on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron the sweatshirt and never take it to the dry cleaner.
