This is a seriously so easy, but all you are going to need is some rice. Got it? place a few spoonfuls of rice in your coffee grinder, enough to just cover the blades, and then grind it well on the espresso setting, which should be the finest setting. Continue to do this and dump out the rice when it is ground. The ground rice should be full of black debris, which is the coffee grounds. Once you go through several cycles, your ground rice should start coming out clean, which means that your grinder is in much better condition.
Oftentimes, this is necessary because the essential oils of the coffee beans will mix with the old grounds in your grinder, causing them to stick to the blades and the inner components. If you want to really get your grinder clean so that you do not have stale coffee grounds sitting in there over and over again, then this is the way to do it. You will immediately notice the difference when you go to brew your next cup of Joe, especially because your grinder is now so fresh and so clean!
