If you love fresh coffee, your grinder is likely your most important tool. Whether it’s a sleek electric burr grinder or a hand-cranked manual model, it’s the first step in turning beans into a delicious brew.
But like any piece of gear, your coffee grinder requires regular maintenance to keep it performing at its best.
In this complete guide, we’ll explore how to clean and care for your grinder—whether it’s blade, burr, manual, or electric.
You’ll learn why maintenance matters, how often to clean your grinder, the exact steps to follow, and how to extend its life well into the future.

Cleaning frequency depends on how much coffee you brew, what types of beans you use, and the grinder style.
| Usage Level | Blade Grinder | Burr Grinder | Manual Grinder |
|---|---|---|---|
| Daily | 1x/week | Light weekly + monthly deep clean | 1-2x/week |
| A few times/week | Every 2 weeks | Every 2-3 weeks | Every 2 weeks |
| Occasionally | Once/month | Once/month | Once/month |
If you’re switching between beans often—especially dark roasts or flavored beans—cleaning more frequently is advised.
Whether electric or manual, burr grinders follow similar cleaning principles. Here’s a breakdown of the monthly deep clean for burr models:
Always unplug electric grinders before cleaning. Remove any remaining beans from the hopper and grind chamber.
Most grinders allow you to unscrew or lift off the top burr and hopper. Set them aside.
Use a brush to sweep away all visible grounds and oils. Pay attention to the burrs, grind chamber, and chute.
Run grinder cleaning pellets through the machine as per the instructions. This helps remove oil and residue from burrs.
Use a damp microfiber cloth to wipe the outside. Don’t use water inside the grinder body.
Make sure all parts are dry and secure before putting everything back together.
Blade grinders are simpler to clean but still need regular attention.
Shake or tap out any leftover particles.
Use a dry cloth or small brush to get into the corners.
Grind ¼ cup of uncooked white rice to help absorb oils and loosen particles. Discard the rice and wipe again.
Use a damp cloth on the outside and let the grinder air dry fully.
Manual grinders usually come apart easily and are great for those who like hands-on brewing.
Unscrew or unclip the burr assembly, crank, and hopper.
Use a soft brush to clean between burr teeth and remove buildup.
Wash the grounds container and handle if they’re plastic or glass. Dry thoroughly.
Ensure all parts are dry before reassembling. Check alignment of burrs to avoid cross-threading.
Some high-end grinders require occasional lubrication of internal parts. Check your manufacturer’s manual for guidance.
Here’s what to keep in mind:
Proper storage also extends the life of your grinder.
Store in a cool, dry cabinet or corner of your coffee setup to minimize exposure.
Burrs and blades don’t last forever, especially with heavy use. Here are some warning signs it’s time to replace them:
