It seems intuitive to do wash your clothes in hot water when doing your laundry. It just seems like hot water should clean dirty clothes better than warm or cold water ever could, right? Wrong! You need to switch to washing in warm or cold water. Here’s why. First, hot water does not clean clothes better. Hot water is also tougher on clothes, helping to wear and tear them faster, as well as fade colors quicker.
More importantly, using hot water to do your laundry is an energy drainer. When washing, 85 to 90 percent of the energy used is for heating the water. Using warm water instead of hot water for two loads of laundry a week will save 500 pounds of carbon dioxide pollution, if you use an electric water heater, or 150 pounds of carbon dioxide, if you use a gas heater. Always use cold water when rinsing!
