How to Deep Clean Your Grinder with Grindz Tablets

Quick answer

Use Urnex Grindz tablets to safely and easily remove coffee oils and stale grounds from your standalone grinder without disassembly.

How to clean your grinder with Grindz tablets

1. Step 1: Empty the bean hopper: Remove all coffee beans from the hopper. If possible, remove the hopper and brush out any loose grounds. Common mistake: leaving a few beans in the hopper, which can mix with the tablets and reduce cleaning effectiveness.
2. Step 2: Set your grinder to a coarse setting: Adjust the grind size to the coarsest setting. This prevents the tablets from being ground too finely, which could cause them to clump or pass through too quickly. Checkpoint: A coarse grind helps the tablets move through the burrs slowly, maximizing oil absorption.
3. Step 3: Add the recommended amount of Grindz tablets: Pour about 1–2 tablespoons of Grindz tablets into the empty hopper. Check your grinder's capacity — for larger grinders you may need more. Common mistake: using too many tablets at once, which can overload the motor. Start with the minimum recommended dose.
4. Step 4: Grind the tablets completely: Turn on the grinder and let it run until all tablets have passed through the burrs. You should see a fine powder coming out. Common mistake: stopping the grinder mid-cycle, which leaves partially ground tablets stuck in the burrs. Let it run fully.
5. Step 5: Discard the ground tablet powder: Remove the grounds bin and discard the powder. Do not use this powder for brewing — it is not coffee. Wipe the bin and the chute area with a dry cloth. Checkpoint: If you see dark streaks in the powder, the tablets are still absorbing oils. You may repeat steps 3–5 for a deeper clean.
6. Step 6: Wipe down the burrs and hopper: With the grinder unplugged, use a stiff brush or dry cloth to remove any remaining powder from the burrs and hopper. Do not use water. Common mistake: using compressed air, which can blow powder into the motor bearings. Stick to brushing. After cleaning, run a small amount of fresh coffee beans through the grinder to purge any residual tablet powder before brewing your next shot.
