Exterior: A non-abrasive damp cloth to wipe down the exterior and load bin of Opus to avoid scratches.
Exit Chute/Anti Static: The anti static technology will work best for about 60 cycles before it needs to be cleaned to operate at its peak performance. To clean it, remove the catch cup, and use the Fellow cleaning brush (or another cleaning brush such as a clean makeup brush or a clean paint brush) and “swipe” around the inside of the exit chute (where the coffee grounds come out). This will clean the chute and help the anti-static mechanisms work well.
Burrs: Take the load bin off, remove the outer burr, and brush the burrs with the Fellow cleaning brush (or another cleaning brush such as a clean makeup brush or a clean paint brush).
