Brush out the burrs and hopper
Every 2 weeksA stepped conical grinder holds stale grounds in the chute more than in the burrs.
What you need
- Stiff dry brush. Dry cloth. Optionally grinder cleaning tablets every few months.
What goes wrong
- Washing burrs in water, which rusts them. Putting the hopper back without seating the burr ring, which throws the grind off completely. Using a damp cloth inside the burr chamber.
The procedure
- Empty the hopper and run the grinder briefly to clear whatever is left in the burr chamber.
