To use this awesome 'Trick or Christmas' sweatshirt, just put it on and enjoy the comfort. When it's time to clean it, remember to machine wash it cold, turning it inside out and washing with similar colors. Only use non - chlorine bleach if it gets really dirty. After washing, you can either hang it up to dry for the best look, or tumble dry on a cool or low heat setting. But don't use fabric softener because it might make the colors fade. Also, stay away from ironing and dry cleaning as they can damage the sweatshirt. This way, your sweatshirt will stay in great shape for a long time.
