Jeans Care - White Streaks on Jeans
Q. What are the white streaks I sometimes see on blue jeans?
A. Blue jeans are often dyed with indigo dye, which is a fugitive dye that bleeds in a water solution. As the washer spins, the edges where the fabric is folded get more abrasion and rougher treatment, causing the color to escape. Turning jeans wrong side out before laundering will reduce these white streaks and give more even fading. To avoid the natural fading that accompanies use of indigo, look for polyester/cotton jeans that are labeled colorfast. They will retain their dark blue better.
