Never wash the section housing the motor -damp-wipe it only.
Safety is crucial with the attachments. Work out a safe drying place for processor blades before you start - don't just leave razor-sharp blades on the drainer.
Clean processor bowls and blender jugs where they live. Half fill the container with warm water, add a drop of washing-up liquid, then turn on the machine and let it clean itself! If the bowl is stained by foodstuffs, processing ice cubes should shift even carrot and beetroot residue. Usually, dried-on cake mix or orange-juice pulp is the most difficult to clean. To ensure that you always wash bowls out immediately, fill a sink with hot, soapy water before you begin.
