Unplug the grinder before cleaning. Wipe the inside surfaces of the bean hopper with a moist cloth at least once a week to avoid a build-up of coffee oils, which can cause discoloration. You may also clean the exterior surfaces with a moist cloth and wipe dry. Do not use any cleaning agents to clean the interior or exterior of the coffee grinder. Do not wash any grinder parts in the dishwasher. Do NOT use rice to clean your grinder.
We recommend cleaning the inside of your grinder every 3-6 months, depending on the type of coffee you’re using and how frequently you grind. Darker roasts are typically oilier and tend to stick to the inside of the grinder more easily. If you do not clean your grinder regularly, you may find that it negatively impacts the flavor of your ground coffee.
The inside of your grinder can either be cleaned manually or automatically by using a dedicated coffee grinder cleaning product.
For deep cleaning, you can remove the upper burr carrier, then use a soft brush and a vacuum cleaner to clean the grinding chamber. See our detailed steps below:
- Unplug the grinder.
- Empty the bean hopper.
- Remove the bean hopper using a Phillips #2 screwdriver.
- Remove the upper burr carrier using a Phillips #2 screwdriver.
- Use a soft brush and vacuum cleaner to remove leftover grounds from the grinding chamber.

A grinder cleaning product will remove coffee oils and particles stuck inside the grinder without disassembly. Be sure to choose one suitable for burr grinders, such as Urnex Grindz or Biocaf Coffee Grinder Cleaning Tablets, and follow the manufacturer’s directions on the packaging.
