How To Clean Coffee Grinder? Step by Step

Everyone agrees that the ideal cup of coffee starts with freshly grounded roasted coffee beans. The essential oils that give aroma and taste begin to dissipate after the coffee bean’s shell breaks. Home-ground coffee has the best flavor but leaves behind oils and grounds that must be cleaned.

However, manual grinders are still accessible if you need excellent exercise before every cup! Electric blade or burr grinders are available.

Blade grinders smash coffee beans with a revolving blade. They are cheap and come in various sizes. Burr grinders ground coffee with two flat sharpened disks or a conical serrated disk. Coffee cafes employ the more expensive conical grinder for their consistency.

When using a coffee grinder, clean it thoroughly to avoid the buildup of oils from the beans. Using rancid oils in your coffee can ruin the taste of your beverage. Here’s how to clean a coffee grinder.

How to Clean a Coffee Grinder

Cleaning your coffee grinder isn’t difficult, but it does require you to go through many stages. To clean your grinder, follow these steps:


  1. Please turn it off and disconnect it from the wall outlet.
  2. Remove hopper and grinding chamber. Remove any coffee dust and oil accumulation with a lint-free towel or coffee filter. If there is any oil residue, remove it with mild soap and hot water. Rinse them promptly to avoid soap flavor contamination and properly dry them to prevent wetting the burrs or motor, leading to corrosion.
  3. Gently twist the outer burr out of the grinder until it comes out of the machine. If you can’t remove the internal burr, leave it there.
  4. All coffee particles, dust, and oils should be removed from the burrs and chute. You should clean every surface you can see or access.
  5. Take your coffee grinder apart and put it back together.
  6. Grind 10 to 20 grams of coffee in a coffee grinder.

This procedure should take you between 10 and 15 minutes in total.

The final step, grinding a little coffee, is significant for two reasons. To begin with, it gives you a chance to calibrate the burrs if they need to be adjusted.

Second, a small layer of coffee oil on the burrs of your grinders can assist in preventing oxidation and corrosion, whereas too much oil buildup is bad.

How to Clean a Blade Coffee Grinder

An absorbing material can collect oil from the blade and grinding chamber when cleaning a blade grinder. A variety of grain-based cleaning tablets are available at coffee shops and online.

1. Add Rice or Grinder Cleaning Tablets

In the hopper of the blade grinder, add one-fourth cup of dry, uncooked rice or the suggested amount of the grinder cleaning tablets.

2. Run the Grinder

To make a fine powder out of grains or tablets, turn on the grinder and run it until everything is reduced to a fine powder.

3. Power Down the Grinder

Once the rice has been crushed, please turn off the grinder and unhook it from the wall outlet to finish the process.

4. Empty the Grinder Hopper

Place the pulverized rice in a garbage can and set it aside. Give the grinder a couple of taps on the edge of the container to free any rice powder that has become stuck in the hopper during the grinding process.

5. Wipe Clean

Then, using the lint-free microfiber towel, wipe out the hopper’s insides. Pay special attention to the area immediately surrounding the blades. Clean the grinder’s exterior by wiping it down with a damp towel.

How to Clean a Burr Coffee Grinder

Cleaning a burr grinder is more difficult. Hand grinders and other types of burr grinders should be uninstalled before cleaning because of the possibility of damaging the components. You should always consult the owner’s manual to learn how to clean your specific model.

1. Remove the Hopper and Clean

Cleaning a burr grinder is easiest when the hopper is empty, which is the case with most of these machines.

Rinse the hopper and any removable gaskets with hot, soapy water after removing them from the device. Dry with a microfiber towel after thorough rinsing with hot water.

2. Turn on the Grinder

If at all feasible, turn on the grinder and let it spin for a few seconds to crush any remaining bits of beans that may have become stuck between the burr blades of the grinder. Remove the grinder from the outlet as soon as possible.

3. Remove and Wash Some Components

According to the owner’s handbook, remove all pieces (apart from the burr) that come into contact with the coffee beans, such as the bin that collects the coffee grounds.

A non-abrasive sponge is used to wash the components in a hot, soapy water sink, then rinsed and dried with a microfiber towel.

4. Remove and Clean the Burr

Discard the flat burr disks or the cylindrical burr. This may require a screwdriver. Use a sharp bottle brush to get rid of coffee grounds attached to the burrs. Use a dry microfiber towel to sponge the bristles and soak any oils.

5. Reassemble the Burr Grinder

Once every component has been completely cleaned and dried, the coffee grinder may be reassembled and is ready for use.

Frequently Asked Questions

Is it possible to clean a grinder in the sink?

Dishwasher-safe parts of your grinder are usually available. If you’re unsure about whether or not your grinder’s bean hopper and grind drawer can go in the top rack of your dishwasher, see the manufacturer’s handbook or website.

Can a Burr Grinder be used to grind spices, grains, or seeds?

Burr grinders should never be used for grinding spices, grains, or seeds. Only coffee beans should be ground with a burr grinder.

A blade grinder can ground little, hard spices like peppercorns and cloves. Between uses, make sure to properly clean the grinder to prevent your cookies from tasting like curry.

Is it possible to grind cocoa beans in a coffee grinder?

It is not advisable to use a coffee grinder to ground cocoa beans. The oily liquid produced by grinding cocoa beans, known as cocoa liquor, is too viscous for your burr grinder to handle.

Making chocolate with your cocoa beans is just as time-consuming and challenging as mastering the art of brewing the perfect cup of joe.


Grinders need to be cleaned regularly, just like any other piece of equipment. Coffee dust and oils accumulate in a grinder’s hopper, burrs, and grind chamber over time.

If not cleaned out, particulates can overburden a motor and cause it to break, and oils can go corrupt and damage subsequent brews. If you crush coffee at home, this tutorial helps you give it a complete cleaning and removes all of these coffee fragments, dirt, and oils.

What are your thoughts? Is it time for you to do some maintenance on your grinder? If you’re willing to put in the time and effort, it’s not that difficult.

Just keep in mind that a well-maintained grinder not only produces better-tasting coffee but will also last longer. And if you are going to venture out of your comfort zone and prepare some inventive, kick-ass coffee beverages – you want a clean machine!

Whether or not this will make cleaning your grinder easier is something we’d appreciate hearing about. Also, if you enjoyed it, please forward it along to your other coffee connoisseurs!
