How does a washing machine clean clothes?
Quick Answer
A washing machine combines water, detergent, heat and mechanical movement of a rotating drum to loosen dirt, then spins at high speed to remove water.
The Full Story
The machine fills the drum with water and mixes in detergent, whose molecules attach to oil and dirt and help lift them off fabric. In a front-loader, the drum rotates and lifts clothes before dropping them, so they tumble through the soapy water; top-loaders may use an agitator or impeller. Heating elements can warm the water, which helps dissolve grease. After rinsing, the drum spins at up to around 1,000 to 1,600 revolutions per minute, flinging water outward through small holes by centrifugal effect. Sensors and a control board manage water levels, temperature and timing for each programme.
