To Keep Your Black Clothes Looking Like New, Wash Them Inside Out.
Black clothes blend in with everything and remove stains like a champion, but they still require extra care if you don’t want them to fade. By turning black clothes inside out, your deep blacks won’t turn dark gray.
Stirring during the wash process destroys the fibers and can fade even the darkest colors. That’s why Consumer Reports’ Kimberly Janeway suggests protecting black clothing on the outside by turning it inside out. This allows the inner invisible fibers of your black garment to protect the visible exterior. Janeway also recommends washing in cold water only and not using detergent as it can leave quite noticeable streaks on darker clothing.
