There’s a simple path to greener laundry: pick the cold water wash cycle! Around 90% of the energy used by washing machines goes to simply heating the water. Many people assume that they’re getting extra cleaning power by washing in hot water but, in most cases, washing clothes in cold water is just as effective as washing clothes in hot water. Hot water is sometimes beneficial when you’re trying to remove oily stains or sanitize heavily soiled items but, otherwise, wears out clothes quickly, causing them to fade, stretch and wrinkle. The hot cycles on most residential washing machines don’t even heat water to the temperatures required to destroy or remove a majority of allergens (55-60°C).
