    Laundry Tweaks Can Help Clothes Last Longer And Pollute Less

    Washing may be to blame. A new study has shown just how much the time and temperature of a wash cycle can affect clothing. It found that clothes lose less dye and fewer fibers when washed in shorter cycles and in cool water. That means they will fade and thin less. These wash settings are greener too — as in better for the environment.
