What is the correct program for towels?

To wash your towels at the right temperature, first look at their fibre composition. If they are made of cotton, simply choose your washing machine’s "cotton" programme, then set the temperature to 40°C. For white cotton towels, you can go up to 60°C. Linen or synthetic fibre towels and bathrobes should not be washed at temperatures that exceed 30°C, as they may be damaged during the wash.
