Cleaning your grinder can seem like a chore but it’s actually pretty easy. Truth is, I actually found it to be a very soothing experience that has helped me appreciate my Comandante grinder even more! Here’s how you should go about it.
Step 1: Collect your tools. I recommend the following.
- Toothbrush. Can be old or new. I grabbed a new one and shall be reserving it for the Comandante from now on.
- Long brush. For places a toothbrush can’t go.
- Toothpick. For getting into nooks and crannies.

Step 2. Remove your grinder from your Madkat grinder stand.
Step 3. Install the hand crank so you can grip the axle and remove the burr assembly.

Step 4. Use a toothbrush to clean off any excess coffee before disassembling the grinder burr. (Something I didn’t do but probably should have!)

Step 5. Unwind the dial all the way. (As if you’re making the grind setting courser.) The dial should come off completely.
Step 6. Remove the burr from the central axle along with the spring.
Step 7. Now that the central burr and spring are disassembled, you can remove the hand crank.

Step 8. Time for cleaning! Use the toothbrush to clean all accessible surfaces on the main body and the burr.
Step 9. Use a long brush for places that are hard to reach like the top bearing and washer cavity.

Step 10. (Optional) If you’re a perfectionist, use a toothpick for the some of the nooks and crannies.

You’re grinder should look like this when it’s all cleaned up.
Step 11. Time to put it back together! Place the hand crank back on so you can assembly the burr set back on.

Step 12. Place the spring in the burr then fit the burr with spring back onto the axle.
Step 13. Thread the dial back onto the axle. (Tip: You could rotate counter clockwise while applying very slight pressure until you feel the adjustment dial drop onto the threads of the axle. Then, rotate clockwise to thread the dial on.)
Step 14. Now that you’re good to go you can put it back into your Madkat electric grinder stand and let it grind away while you prep/plan your next coffee experiment!
