    Notice a stale, oily smell from your grinder after weeks of daily use? That is rancid coffee oil building up inside. The Capresso Infinity conical burr grinder is a workhorse in many U.S. home kitchens. But neglect it long enough, and even a premium Capresso starts tasting like a gas station cup. 

    In our Capresso Infinity Review, we noted its excellent grind consistency. However, keeping that quality takes work. Here is exactly how to clean Capresso Infinity grinders. I will share the full process, the tools you need, and how often to do it.

    Why Cleaning Your Capresso Infinity Actually Matters

    Coffee oils go stale very fast. When you grind beans every day, built-up residue silently coats the inside of your machine. This hidden grime ruins every cup you brew.

    What Happens When You Skip Cleaning

    If you skip cleaning, stale oils coat the conical burrs. This leads to a bitter, rancid flavor in your morning mug. Fine coffee dust also packs tightly into the exit chute. This creates a huge clog risk and causes uneven particle sizes.

    If your fresh grounds smell musty instead of roasted, that is a big red flag. I once ignored my grinder for a month. The motor strained hard just to push packed debris out. Long-term, this extra strain can actually damage the motor.

    How Often Should You Clean It?

    How often you clean it depends on your daily routine. For light use, do a full clean every three to four weeks. For daily use, brush it out weekly and deep clean every two weeks.

    If you switch to oily dark roasts or espresso blends, clean it right away. Those heavy oils stick to metal fast. Trust your nose as a sensory cue. If the grinder smells stale mid-grind, do not wait. Learning how to clean Capresso Infinity models quickly saves you time and saves your coffee.

    Tools Needed to Clean a Capresso Infinity

    Gather your supplies before you start. Stopping mid-clean to hunt for a brush wastes time. It also lets stray coffee grounds scatter across your counters. Having the right tools makes the job much easier.

    Cleaning Supplies Checklist

    Here is exactly what you need to do the job right:

    Cleaning Supplies Checklist
    • Cleaning brush: Use the included Capresso brush or a stiff pastry brush.
    • Dry microfiber cloth: Perfect for wiping away oily coffee dust.
    • Grinder cleaning tablets: I recommend Urnex Grindz. They are food-safe and easy to find.
    • Small Phillips screwdriver: Keep this handy for deep cleans.
    • Mild dish soap: Pick a fragrance-free soap to avoid flavor transfer.
    • Toothpick or wooden skewer: Great for clearing tight spaces in the chute.

    What to avoid: Never use compressed air cans. They just blow loose grounds deeper into the motor. Also, avoid using wet paper towels inside the burr chamber. Moisture creates rust on metal parts fast.

    Note: Capresso Infinity parts are not certified BPA-free for dishwasher use. High heat easily warps the hopper seal. Always hand-wash your removable parts.

    Quick Weekly Clean — 5 Minutes, No Disassembly

    This is your everyday maintenance habit. It takes less time than waiting for your Keurig to heat up. Doing this simple sweep keeps your daily brews tasting fresh. If you are still figuring out your machine’s settings, check out our guide on How to Use Capresso Infinity.

    Step-by-Step Weekly Brush Clean

    Follow these steps to clear out old grinds quickly:

    Step-by-Step Weekly Brush Clean
    1. Unplug the grinder: This is non-negotiable every time you clean.
    2. Remove the bean hopper: Twist it counterclockwise and carefully lift it off.
    3. Empty the beans: Dump any leftover beans into an airtight container.
    4. Brush the upper burr ring: Sweep your brush in a circular motion for about 8 to 10 passes.
    5. Tap out loose grounds: Tilt the grinder over a trash can and tap the base gently.
    6. Clear the chute: Push the bristle tip into the grounds chute opening to clear packed fines.
    7. Wipe the hopper: Use a dry microfiber cloth on the inside. Do not use water.
    8. Run it empty: Reinstall the hopper and plug the machine back in. Run it empty for 3 to 5 seconds to clear out residual grounds.

    You will notice a difference right away. The grinds will actually sound crisper as they exit the chute. Plus, you will not catch that stale smell on your brush anymore. Knowing how to clean Capresso Infinity grinders weekly stops bad flavors before they start.

    Monthly Deep Clean — Full Burr Removal

    Doing a monthly deep clean is the most important part of how to clean Capresso Infinity models. This habit is where you earn the difference. It separates a grinder that tastes cheap from one that punches above its price.

    Remove the Upper Burr

    First, always unplug the machine. Remove the hopper using the same twisting motion as before. Look inside the chamber for the upper burr. It is a raised black disc. Turn it counterclockwise. Most models release with two or three turns. Lift it out carefully. Check the burr teeth for bean fragments. Note the smell right away. Fresh roast residue is normal. A sour or rancid smell means this clean is overdue.

    Clean the Burrs and Chamber

    Tap the upper burr over your trash can to drop loose grounds. Use your cleaning brush on the burr teeth. Work into every groove on both sides. Wipe it with a dry microfiber cloth. Never put moisture on metal burrs. It causes rust quickly. Use a toothpick to clear packed grounds stuck in the gaps. Next, brush inside the grinding chamber. 

    Work from top to bottom in circular passes. Push the bristle tip inward to clear the outlet chute. Wipe the chamber walls with your dry cloth. The metal texture should feel smooth, not gritty.

    Clean the Hopper and Grounds Container

    Wash the hopper in warm water. Add a tiny drop of fragrance-free dish soap. Rinse it very well. Leftover soap ruins coffee flavor fast. Let it air-dry completely for at least an hour before putting it back. Wash the grounds container the exact same way. Check the rubber hopper seal ring. 

    If it feels stiff or cracked, it is time for a new one. You can easily find spares when looking for Capresso Infinity Replacement Parts.

    Reassemble Correctly

    Put the upper burr back in. Align the tabs and turn clockwise until snug. Do not overtighten it. Put the dry hopper back on. Now is the perfect time to run Urnex Grindz tablets. After that, grind about 15 grams of cheap beans. This purges any leftover tablet dust. Throw those grounds away. Never use them in your coffee.

    Using Grinder Cleaning Tablets (Urnex Grindz)

    Tablets reach tight spaces that brushes simply miss. Think of them like running a heavy-duty cycle on a Cuisinart dishwasher. It is a systematic, totally hands-off process.

    How to Use Grindz Tablets

    Add about 35 to 40 grams of tablets into the empty hopper. Change your grind size to a coarser setting. This protects the burrs while the hard tablets run. Grind the tablets through completely. Next, follow up with 20 grams of cheap coffee beans. This acts as a purge. 

    I usually do two full passes just to be safe. Throw away all the purge output. The tablets are certified food-safe. However, they taste terrible. Never brew the leftover dust.

    How Often to Use Tablets

    If you use your grinder daily, run tablets once a month. Light users can do this every six weeks. You should also use them right after switching beans. If you just finished a bag of oily dark roast, run tablets before starting a light roast. This stops the heavy old oils from ruining the bright flavors of your new beans.

    Troubleshooting Common Cleaning Problems

    Sometimes cleaning raises new questions. Here is what most people run into after putting things back together.

    Grinder Still Smells After Cleaning

    Did you run purge beans? If not, run 20 grams through and discard them. Was the hopper completely dry before you reinstalled it? Trapped moisture holds bad odors easily. Also, check the ground chute. Compacted fines hide deeply and are often missed. If your machine refuses to spin at all, read our guide on Capresso Infinity Not Working.

    Grinds Coming Out Clumpy After Cleaning

    Your upper burr might not be seated fully. Remove it, realign the tabs, and carefully reseat it. Static buildup is another common cause. Wipe the burr with a barely damp cloth and air dry for 10 minutes. Watch out for humidity in your beans. Store beans away from steam. A spot near your stovetop or Breville espresso machine is a bad location.

    Grinding Sound Changed After Reassembly

    If it sounds unusually loud, the upper burr is slightly misaligned. Simply remove and reseat it. Old debris might still sit in the chamber. Re-brush and re-tap the machine. If the grinding sounds metallic, stop right away. Check the burrs for a broken tooth.

    Tips to Keep Your Capresso Infinity Cleaner Longer

    Prevention beats cleaning. A few smart habits will easily extend the time between your deep cleans.

    First, avoid oily beans when you can. Dark roasts coat metal burrs much faster than dry-process roasts. I noticed my burrs get sticky twice as fast with heavy French roasts. Store your beans dry. Keep them in an airtight container at room temperature away from heat.

    Never grind flavored beans. Artificial hazelnut or vanilla oils are nearly impossible to remove from metal burrs. Run a few extra grams of cheap coffee through after each daily use. This pushes soft residual fines out of the chute.

    Keep the grinder away from your kettle or stove. Daily steam easily accelerates oil oxidation inside the grinding chamber. Lastly, wipe the hopper rim weekly with a dry cloth. Grounds love to accumulate right at that seal line.

    Frequently Asked Questions

    Can I wash Capresso Infinity burrs with water? 

    Metal burrs are strictly dry-clean only. Water causes rust on metal burr teeth almost instantly. The plastic hopper and grounds container are water-safe. The burrs and the main chamber are not.

    Can I put Capresso Infinity parts in the dishwasher? 

    No. High heat warps the plastic hopper and melts the rubber seal. You must hand-wash and air-dry these parts to keep them safe.

    How do I know if my burrs need replacing? 

    Look for uneven grind sizes even after a fresh clean. You might also spot visible flat edges or chipping on the burr teeth. A dramatic increase in your daily grinding time is another huge clue. Replacement burrs are available direct from Capresso.

    Is Urnex Grindz safe for Capresso Infinity? 

    Yes, absolutely. These tablets are food-safe and certified for burr grinders. They are used widely in commercial café settings to absorb rancid oils safely.

    A clean Capresso Infinity guarantees better flavor, consistent grinds, and a longer lifespan. Try doing a light brush clean this week. Then, schedule a monthly tablet clean on your calendar. Your morning cup deserves much better than two-month-old coffee oil. Taking fifteen minutes now gives you better coffee every single day.
