Effective removal of stains no longer requires high temperature or additional treatment of clothing before the wash. The perfect combination of temperature, time, and water will automatically remove four types of stubborn stains: fruit (oranges, tomato sauce); organic stains (fat, butter, eggs, grass); wine (dark fruit juices, ink); and coffee (tea, yoghurt, pasta, make-up). The StainExpert function is available in the Superior washing machines.
