The stable disc grinder of the Eureka Mignon can be cleaned of grinding residues with a narrow vacuum cleaner or a brush. Thanks to the patented Eureka system, you don't lose your personal grind setting. It is best to use a wet cloth to clean the housing and the bean container. If there are particularly stubborn grease residues in the bean container, you can also use a little washing-up liquid to help. You should clean your Eureka Mignon regularly so that you can enjoy particularly aromatic coffee or espresso for a long time.
