Cleaning removes coffee residue

Coffee oils and grounds accumulate in parts that contact coffee. The group, portafilter, basket and grinder have different care instructions. Use the exact cleaning method your manufacturer specifies for each part.

Descaling addresses mineral buildup

Descaling is a different procedure aimed at mineral deposits in the water path. A dirty basket does not establish that a machine needs descaling, and a descaling cycle does not replace routine coffee-residue cleaning.

Use model-specific instructions

Some machines require a particular product, dilution or service process. Do not assume vinegar or a third-party chemical is safe. Never mix cleaning products; follow the label and your machine manual.

Make a realistic routine

Keep a clean cloth accessible and allow parts to cool before handling. Record the date of maintenance and follow your model’s alerts or manual rather than a universal monthly schedule. Consult the maker or a technician if flow remains abnormal.
