Tap out loose grounds, then use a small brush or vacuum to clear coffee dust from the burrs and chute. For a deeper clean, run grinder-cleaning pellets through per package directions, then purge with a small amount of beans. Wipe the hopper and exterior with a slightly damp cloth and mild soap, dry completely, and reassemble. Avoid water on metal burrs and never use oil-based cleaners.

For blade grinders, wipe out grounds with a dry paper towel, then use a damp cloth with a little baking soda to lift oils; dry thoroughly.
