To use your Rustenico Busters sweatshirt, just put it on and enjoy its comfort. When it's time to clean, remember to machine wash it cold, turning it inside out and washing with similar colors. Only use non - chlorine bleach if needed. After washing, you can either hang it to dry for the best look or tumble dry on a cool or low - heat setting. Don't use fabric softener as it can make the colors fade. And don't iron or dry clean it to keep the sweatshirt in good condition.
