67. Wash only full loads of clothes, and be sure to set the water level appropriately.

68. Use hot water only for very dirty loads, and always use cold water for the rinse cycle.

69. Clean the lint screen on the dryer every time you use the machine. A clogged lint screen can make your dryer use up to 30 percent more energy – and it can be a fire hazard.

70. Remove clothes from the dryer while they’re still damp and hang them up. This will save energy, prevent static and reduce wrinkles and shrinkage.

71. Dry one load of clothes immediately after another. This will minimize heat loss, reducing warm-up and drying times.
