stainless steel model.
Remove the detachable accessories in the interior of the appliance and
clean it with water and liquid detergent. Plastic parts cannot be washed in

Wash the interior of the appliance with lukewarm water, in which you
add one or two spoonfuls of vinegar.
Switch Off the Appliance When Not in Use
