Most of the time, you should wash delicate things like lace, wool, or silk in cold water. Hot water can set stains and cause delicate materials to shrink, fade, and get permanent creases.
Should you clean stains with hot or cold water? Even though hot water kills more bacteria than cold water, cold water is better at getting rid of stains. Of course, the temperature of the water isn’t the only thing that affects how clean clothes get. In addition to knowing whether to use hot or cold water on a stain, you should also think about the color of the fabric and the kind of stain. The best results will come from pre-treating stains with safe, natural cleaners that you probably already have on hand.
People usually say that you should wash all white clothes in hot water, but this isn’t always the best thing to do. Some materials can shrink and get weaker in hot water (over 130 degrees Fahrenheit), but they won’t get clean in water that is too cold (between 60 to 80 degrees). What’s the trick? Nelson says that lukewarm water, which is usually between 90 and 110 degrees Fahrenheit, is the best way to wash white sheets. Lindsey Boyd, co-founder of The Laundress, agrees with this and says that warm water is usually best because it can get rid of body oils, stains, and built-up dirt while causing the least amount of shrinkage. She worries that using hot or warm water could cause some things to fade or get smaller. The manufacturer says, “Warm water will shrink them more gradually over several washes, while hot water will shrink them to their full shrinking potential after just one wash.”
