How to use your DAObiwan's Stained Glass Vengeance sweatshirt? Just put it on and show off your unique style! When it comes to cleaning, always machine wash it cold and turn it inside out. This helps keep the colors vibrant. Wash it with similar colors to prevent any color transfer. Only use non - chlorine bleach if there are stubborn stains. After washing, hanging it to dry is the best way to maintain its shape and fabric quality. But if you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can fade the colors, so skip it. Also, don't iron or dry clean this sweatshirt as it may damage the fabric and the design.
