How to use this sweatshirt is super easy - just put it on and enjoy the Halloween spirit! When it comes to care, make sure to machine wash it cold and turn it inside out. Wash it with similar colors to avoid color bleeding. Only use non - chlorine bleach if it gets really dirty. After washing, you can either hang it up to dry for the best results or tumble dry it on a cool or low - heat setting. Don't use fabric softener because it might make the colors fade. And remember, don't iron it or take it to the dry cleaner. This way, your sweatshirt will stay in great shape for a long time.
