Keeping Your Coffee Grinder Clean
Clean your grinder by running dry, uncooked rice through the burrs to dislodge old oils and grounds, followed by a thorough wipe-down of the hopper and chute with a dry cloth. Regular maintenance prevents stale, rancid oils from tainting your daily cup and keeps the burrs moving freely.
Consistency starts with a clean burr set
Old grounds turn bitter and stick to the burrs, creating friction that ruins the grind size. Never use water on the internal mechanism unless the manufacturer explicitly states the parts are dishwasher safe.
- small, stiff-bristled brush
- dry uncooked white rice
- clean microfiber cloth
- vacuum with a hose attachment
Dry cleaning with starch
Running a handful of raw white rice through the grinder acts as an abrasive that pulls old coffee oils and fine dust off the burr edges without introducing moisture.
The method.
Unplug the unit
Always disconnect power before reaching into the burr chamber to prevent accidental engagement.
Clear the hopper
Remove the bean hopper and wipe it with a dry cloth. Use the vacuum hose to pull loose dust out of the chute.
Brush the burrs
Use a stiff brush to clear grounds from the teeth of the burrs. Spin the burrs manually if possible to reach every crevice.
Run the rice
Pour a small handful of dry rice into the hopper and run the grinder until it is all processed. Discard the resulting white powder.
Final vacuum
Perform one last pass with the vacuum hose to ensure no rice starch remains inside the chute.
When it doesn't go to plan.
Wipe the bean hopper with a slightly damp cloth only if it is removable, then dry it completely before reattaching.
Avoid oily dark roasts if you want to keep the machine clean longer; they coat the burrs much faster than light roasts.
Store the grinder in a cool, dry place to prevent moisture from causing grounds to cake inside the chute.
The ones that keep coming up.
Can I use soap and water?
No. Water causes rust on metal burrs and can damage the electrical motor. Stick to dry cleaning methods.
How often should I clean it?
If you brew every day, a thorough cleaning once a month is sufficient. If you switch between different coffee beans, brush out the chute between uses.
