Daily: Toss the coffee grounds. Wash the carafe and other removable parts, such as the lid and filter basket, with a soft sponge in warm soapy water. Rinse and towel dry, or set aside to air dry. Wipe off coffee splatters on the machine with a damp paper towel.
Every 3 months (or more frequently, you've got hard water): Prep a store-bought descaling solution, or mix up your own using equal parts vinegar and water. Pour it in the water chamber and run the machine through one cycle to clean out any buildup. Follow with at least two cycles of plain water to flush out the solution. Unplug the machine and soak the removable parts in soapy water or a solution of one part baking soda to two parts hot water for 15 minutes. Scrub the parts with a soft sponge, rinse and dry as above. Wipe the surface of the machine, including the heating plate, with a damp paper towel.
