These DeepFriedArt Science Book Club hoodies are super easy to use. Just put them on and enjoy the comfort and style. When it comes to washing, use cold water and turn them inside out. Wash them with similar colors to avoid color bleeding. Only use non - chlorine bleach if really necessary. After washing, hanging them to dry is the best way to keep their shape. If you're in a hurry, you can use the cool or low - heat setting on your dryer. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry - clean these hoodies to keep them in top condition.
