 If you can, consider a cold wash a few times a week and work to reduce your reliance on hot and warm washes for your clothing. In doing this, you work to cut back on your use of warm and hot water, but also give your clothes the chance to last a little longer too. All using less of dirty power plants. Keep in mind that in-store you will find cold wash specific laundry detergents that work excellent in cold wash loads, and so stains and other impurities will still be removed from your garments.
