How to use your DinoMike's Grim Times sweatshirt: Just put it on and enjoy the comfort! When it comes to cleaning, throw it in the washing machine on a cold cycle. Make sure to turn it inside out and wash it 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 look, or you can use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean the sweatshirt, as it may damage the fabric.
