Use Fine Sugar To Easily Clean Your Coffee Grinder
By Aimee Lamoureux
Not regularly cleaning your coffee grinder can cause leftover oils, grease, particles, and debris from your coffee beans to get lodged into it, which, in turn, can negatively impact the taste of your brew. The good news is that table sugar can easily clean that unpleasant residue clinging to your coffee grinder.
Since sugar is neutral and absorbent, it effectively soaks up leftover oils and odors from the blades of your coffee grinder, leaving them fresh and clean. All you need to do is run about 1/4 cup of sugar through the machine — the same way you grind coffee beans — until it becomes fine and powdery.
Finally, wipe off the grinder with a damp paper towel, and you'll have a clean coffee grinder ready to prepare your next perfect cup of brew. However, if you're out of sugar, other everyday ingredients, such as rice and kosher salt, can also be used to absorb old odors and oils and clear out trapped grounds.
