Cleaning the Gemini
Regular cleaning and preventive maintenance is essential in keeping your coffee brewer looking and working like new.
To clean the coffee brewer and components, prepare a mild solution of dish washing detergent and warm water.

products promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WAR-
