To wash dark clothes, it is recommended to use cold water, around 60-80°F, to preserve the original colors of the clothes. Cold water helps prevent dark clothing from fading, and it is better for the clothes as hot water can cause clothes to fade in color. It is also important to select the appropriate setting depending on how soiled the clothes are and what fabric theyre made of, and to use a liquid detergent tailored to dark clothing (or one without a bleach component) to prevent fading. It is best to check the care tag on the clothing for proper washing and care instructions. Although cold water helps prevent dark clothing from fading, frigid outdoor temperatures may cause the washers water temperature to fall below 40°F, rendering even detergents designed to work in cold water ineffective. If you live in an area with particularly chilly winters, dont use the cold-water wash setting during that time of year. Instead, select a warm-water wash and a cold rinse.
