How to Maintain your Coffee Grinder
Clean equipment is an essential part to making coffee drinking enjoyable. This means a clean coffee grinder. Thankfully cleaning the coffee grinder is simple and easy. First, I would like to mention some coffee lovers like to run throw away coffee beans through the grinder to get rid of old coffee left inside the grinder. To start maintenance you’ll need: 1 cup white rice, but if you have a grinder with any metal parts, you would not use rice or soap. Some cold water would be enough to wipe down a grinder with metal parts.
You’ll also need a stiff toothbrush, other stiff brush like a paint brush, for example, a clean damp cloth and the dirty grinder. For a Burr grinder, place ½ cup white rice in grinder and grind using the fine ground setting. If your grinder has a hopper, remove it and take brush to clean hard to reach places then wipe with damp cloth. Remove any loose parts inside the grinder and use respective brush to clean the parts thoroughly.
You can also hold the grinder over the trash can to dump the old coffee out, if you grinder is small enough. You can also use a can of compressed air. Wipe any exposed areas of the grinder with a damp cloth. Wipe them even if the appear clean. Put the grinder back together making sure any removed parts get wiped. Run the last of the ½ cup of white rice through the grinder. If the rice still looks dirty, run another cycle of rice. Try to do this until rice comes out clean. Grind approximately one cup of coffee beans you won’t mind throwing away. THIs helps rid the grinder of any residual rice.
Next are blade grinders. You want to fill the grinder with rice covering the blades. Pulse the blades for about one minute. Take rice out and wipe internal parts with a damp cloth. Use brushes to get the harder to clean spots inside grinder and blade. Replace grinder if any torn power cords are found to avoid any fires. For both types of grinders, it is recommended to have weekly maintenance. Also you can substitute paper towel and water instead of damp cloth. This is really all you need to maintain a great coffee grinder, whether you get the cheaper blade grinder or that fancy French press Burr grinder, grinder maintenance is simple!
