To use your Arinesart Vintage Dragon sweatshirt, simply put it on and enjoy its comfort and style. When it's time to clean, machine wash it cold and turn it inside out. Wash it with clothes of similar colors. Only use non - chlorine bleach if it's really needed. After washing, you can hang it up to dry for the best results, or you can tumble dry it on a cool or low - heat setting. Just remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean the sweatshirt to keep it in good condition.
