Cleaning coffee equipment: oils and scale require different attention

Coffee residues can remain in a carafe, basket and other parts of a brewing system. Mineral scale from water is another kind of buildup. The source discusses both, but they should not be treated as though one cleaning action necessarily removes every deposit from every machine.

Follow the equipment maker's instructions for routine washing and for any separate descaling process. Check which parts are removable, which can be washed with detergent and which require a particular product or procedure. A vinegar mixture described for one situation should not be assumed compatible with every coffee maker, gasket, coating or metal.

Allow parts to be rinsed and dried as directed before the next preparation. Keep track of the maintenance tasks rather than waiting for a clearly unpleasant cup. If a machine has a cleaning indicator, read what it actually requests; washing a carafe is not necessarily the same as completing the indicated cycle. Good maintenance is a repeatable routine matched to the equipment, not a competition to use the strongest solution.
