Using your Colinvania sweatshirt is easy. Just put it on and enjoy the comfort it offers. When it comes to cleaning, machine wash it in cold water, turning it inside out and washing with similar colors. Only use non - chlorine bleach if it's really dirty. After washing, you can hang it to dry for the best results, or you can tumble dry it on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so it's better not to use it. Also, don't iron or dry clean your sweatshirt to keep it in good condition.
