These 'Cosmic Wonderland' tank tops are super easy to use. Just put them on and enjoy the comfort! When it's time to clean them, remember to machine wash cold and turn them inside out. Wash them with similar colors to avoid color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, you can either hang them to dry for the best results or use the cool/low heat setting in the dryer. Don't use fabric softener because it can make the colors fade. And don't try to iron or dry clean these tank tops as it may damage the fabric. That way, your tank tops will stay in great shape for a long time.
