Keeping Your Coffee Gear Clean
Coffee oils turn rancid quickly, leaving a bitter, stale film on your equipment that no amount of expensive beans can mask. Regular maintenance requires only hot water and a mild detergent for daily parts, plus a targeted descaling process every few months to dissolve the mineral deposits that choke your machine’s flow.
Don't use the dishwasher.
The high heat and harsh chemicals of dishwasher tablets warp plastic seals and strip the protective finish from metal components. Stick to hand washing in the sink.

Clearing the Acid
After descaling, you must run at least two full reservoirs of clean water through the system. If you smell or taste vinegar at the end, run one more cycle before brewing coffee.
The method.
Daily Rinse
Disassemble the portafilter, basket, or carafe immediately after brewing. Rinse with warm water and wipe down the group head or shower screen with a damp cloth to remove loose grounds.
Soak the Parts
Once a week, soak removable plastic and metal parts in warm, soapy water. Use a soft brush to scrub the underside of the filter basket where coffee oils congregate.
The Descaling Mix
Combine equal parts vinegar and water in your machine's reservoir. Run half the solution through the brew cycle, then turn the machine off and let it sit for 30 minutes to break down interior scale.
Final Purge
Finish the brewing cycle with the remaining solution. Empty the carafe and run two full reservoirs of plain water through the system until the vinegar scent dissipates entirely.
When it doesn't go to plan.
Wipe the steam wand immediately after each use; milk proteins harden into a stubborn crust if left to sit.
If your machine has a permanent mesh filter, boil it in water for 5 minutes once a month to loosen trapped oils.
Always leave the bean hopper lid and water reservoir cover slightly ajar when the machine is not in use to prevent mold growth.
The ones that keep coming up.
How do I know if my machine needs descaling?
The water flow will slow down significantly, or the machine will make a louder, strained pumping noise compared to its usual sound.
Can I use lemon juice instead of vinegar?
Avoid citrus juices; the pulp and sugars can clog internal sensors and valves, creating more trouble than they solve.
