Here's how to get the most out of your DAObiwan Stained Glass Vengeance crewneck sweatshirt. When it's time to clean it, just toss it in the washing machine on a cold cycle. Make sure to turn it inside out and wash it with similar colors. If it needs a bit of a boost, use non - chlorine bleach. After washing, hanging it to dry is the best way to keep its shape, but if you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean it, as this could damage the fabric. Enjoy wearing your unique sweatshirt!
