To use this sweatshirt, simply put it on and enjoy the comfort. When it's time to clean, remember to machine wash it cold and turn it inside out. Wash it with similar colors to prevent color bleeding. Only use non - chlorine bleach if needed. After washing, you can hang it to dry for the best result, or you can use the tumble dry function on a cool or low - heat setting. Don't use fabric softener because it might make the colors fade. Also, avoid ironing or dry - cleaning the sweatshirt to keep it in good condition.
