The Easy Guide to Cleaning Your Manual Coffee Grinder ...
For cleaning manual coffee grinder burrs and other small parts, get a bowl of soapy water and dip a Q Tip in it. You can then use the Q Tip to lightly scrub the microgrounds and oils off the smaller parts. I don''t suggest using the dishwasher to clean any part of the grinder. Finding the smaller parts if they move around would be a nightmare.
