Tips Wash & Rinse in c old water. Pre-soak c lothes in

detergent instead to improve c leanliness

If buying new washing mac hine, buy front-loader

Wash in full load

Other benefits

Hot water shrinks your c lothes, and fades andwears your c lothes out faster.

Using warm water for the rinse c yc le doesn'tget your c lothes any c leaner.

water
