To use this Pewter City Gym long - sleeve crewneck sweatshirt, just put it on and enjoy the comfort. When it comes to cleaning, machine wash it in cold water and turn it inside out. Wash it with similar colors to avoid color bleeding. Only use non - chlorine bleach if it really needs it. After washing, hanging it to dry is the best option. 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 skip it. Also, don't iron the sweatshirt and don't take it to the dry cleaner. This way, your sweatshirt will stay in great condition for a long time.
