To use this sweatshirt, simply put it on and enjoy its comfort. When it's time to clean, machine wash it cold, turning it inside out and washing with similar colors. Only use non - chlorine bleach if necessary. After washing, you can hang it to dry for the best results, or tumble dry it on cool or low heat. Be careful not to use fabric softener as it can make the colors fade. Also, don't iron or dry clean the sweatshirt to keep it in good condition.
