How to Clean a Coffee Grinder (Burr and Blade) Without Special Tools
Stale oils and trapped fines quietly ruin fresh beans. A five-minute monthly cleaning with a brush and a dry cloth keeps any grinder tasting new — here's the routine for burr and blade models alike.

Your grinder touches every bean you brew, and coffee leaves two things behind in it: fine dust that packs into corners, and oils that go rancid within weeks. Skip cleaning long enough and even a fresh, expensive bag starts tasting dull and ashy. The fix costs five minutes a month.
The monthly dry-clean routine
Clean a burr grinder in five minutes
Run it empty
Grind out the last stragglers, then unplug it (or for a hand grinder, empty the hopper and catch cup).
Remove the burrs
Most hoppers and outer burrs twist out without tools. Check the manual once — after that it's muscle memory.
Brush everything dry
Use a stiff brush or clean paintbrush on burrs, chute, and threads. A dry cloth wipes the bin. Never rinse the burrs — water invites rust and clumping.
Tap out the chute
The exit chute traps the most fines. Brush it through and tap the body over a bin until nothing falls.
Reassemble and season
Reassemble, then grind and discard a few grams of beans to sweep away loosened dust.
Blade grinders are simpler: unplug, wipe the bowl with a dry cloth, and dislodge packed dust around the blade base with a brush. If odors linger in either style, grinding a small handful of plain white rice absorbs oils — check your manual first, as a few makers advise against it.
