To use this sweatshirt, simply put it on and enjoy its comfort. When it gets dirty, machine wash it cold and turn it inside out. Wash it with similar colors to avoid color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, hanging it to dry is the best way. If you're in a hurry, you can tumble dry it on cool or low heat. Don't use fabric softener as it can make the colors fade. Also, avoid ironing and dry cleaning the sweatshirt to keep it in good condition.
