To use these Holiday Guardians tank tops, simply put them on and enjoy their comfort all day. When it's time to clean, machine wash them cold and turn them inside out. Wash them with similar colors to avoid color bleeding. Only use non - chlorine bleach if needed. After washing, you can either hang them to dry for the best results or tumble dry on a cool or low - heat setting. Remember, using fabric softener can make the colors fade. And don't try to iron or dry clean these tank tops, as it might damage the fabric.
