A clean washing machine soap dispenser contributes considerably to hygienic washing. You should therefore clean the draw approximately every two months and remove any washing powder and conditioner residues. This avoids unpleasant odours and bacteria from forming.
With stubborn dirt, clean the draw in the following order: completely remove the draw from the machine by operating the lock in the middle. Allow it to soak in a wash basin and remove the residues with a cleaning cloth or small brush, for example an old toothbrush. For stubborn deposits such as limescale, please use the appropriate cleaner such as the washing machine cleaner recommended by Bosch.
