How to Clean a Coffee Grinder
Here's a quick way to clean your coffee grinder and eliminate odors, so you can use it for something else, like spices or nuts.
To clean an electric coffee grinder, just add a small amount of rice or a slice of stale bread and turn it on until the rice or bread is finely ground. Simply wipe out the rice or bread crumbs with a dry paper towel.
The dry, hard rice or bread cleans the coffee grounds from the sides and blades, and absorbs the sticky oils. This works great for removing both coffee odors and pungent smells from grinding spices, getting you ready for the next grind.
