HE laundry detergents and HE washing machines were developed and engineered to work together. How come you can only use HE detergent with an HE washer? HE washing machines operate very differently than standard washers, so they require a special kind of soap in order to wash clothes effectively.
HE laundry detergent is a unique kind of detergent designed and produced specifically for HE washing machines. “HE” stands for high efficiency and it designates a washing machine that is made to reduce the amount of water and energy used in each load of laundry.
