To use your Alemaglia 'I Hate You 3000' sweatshirt, simply put it on and enjoy its comfort. When it comes to washing, turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if it's really dirty. After washing, you can hang it 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 skip it. Also, don't iron or dry clean the sweatshirt to keep it in good shape.
