Using these Uncle Spengler hoodies is easy. Just put them on and enjoy the comfort. When it's time to clean them, machine wash them in cold water, turning them inside out and washing with clothes of similar colors. Only use non - chlorine bleach if there are stains. After washing, you can hang them to dry for the best results, or use the tumble dry function with cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, avoid ironing and dry cleaning these hoodies to keep them in good condition.
