These Kharmazero Space Rocks tank tops are easy to use. Just put them on and enjoy their comfort all day. When it comes to washing, remember to use cold water 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, it's best to hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. Keep in mind that fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these tank tops, as it may damage the fabric.
