Dark clothing can fade quickly, but you can keep it at bay by washing them on a short cycle, always washing them inside out and hanging them to dry — among some other tips in this video from Consumer Reports. When combined with other methods to preserve their colour, like washing your clothes in cold water or turning them inside out, a short wash cycle keeps your dark clothing from fading, and you may have never thought to do it. Don't worry — a short cycle won't mean your clothes leave the washer dirty either, especially if you're washing them after normal wear. Check the settings on your washing machine to see which cycle is the shortest. For more tips for preserving your dark clothes, check out the video above.
