To clean a coffee maker, start by wiping down the exterior and removable parts like the carafe, lid, and filter basket with warm soapy water. For a deeper clean, especially to remove mineral buildup (descaling), run a brewing cycle with a solution of half white vinegar and half water. After the descaling cycle, run two cycles with fresh water to rinse out any vinegar residue. Also, hand-wash or dishwasher-clean parts that are removable, and leave compartments like the water reservoir open to dry. For daily maintenance, a quick rinse and wipe is enough, while a monthly deep cleaning with vinegar or commercial descaling tablets is recommended to keep the machine in good shape and ensure great tasting coffee.
