According to the search results, the temperature at which you should wash colors depends on the type of fabric and the color of the clothes. Here are some general guidelines:
-
Cold Water (80°F): For dark or bright colors that bleed or delicate fabrics, use cold water. Cold water also saves energy, so it is a good choice if you want to be eco-friendly.
-
Warm Water (90°F): For man-made fibers, knits, and jeans, use warm water. Most of your clothes can be washed in warm water. It offers good cleaning without significant fading or shrinking.
-
Hot Water (130°F or above): For whites, typically dirty clothes, and diapers, use hot water. Hot water is best to remove germs and heavy soil. However, hot water can shrink, fade, and damage some fabrics, so be sure to read your clothing labels before selecting the hot option.
Its important to note that the lower the temperature of the water, the more detergent you need. If the temperature of the water is below 60°F, no soap or detergent performs well. But don’t make the water too hot. Washing heavily soiled articles with hot water can set stains. For heavily soiled clothes, prewash them in cool water, then wash them again in water that is 130°F or higher. The rinse water can always be cold without any harmful effects on the wash load.
In summary, for washing colors, it is generally recommended to use cold water, especially for dark or bright colors that bleed or delicate fabrics. However, warm water can also be used for most clothes, while hot water should be reserved for whites and heavily soiled clothes.
