To use this Olipop 'Hit Me' sweatshirt, simply put it on and enjoy its comfort. When it's time to clean, make sure to machine wash it in cold water, turning it inside out and washing with similar colors. Only use non - chlorine bleach if it gets really dirty. After washing, you can hang it up to dry for the best results, but if you're in a hurry, you can tumble dry it on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so don't use it. Also, don't try to iron or dry clean the sweatshirt as it may damage the material.
