  • Water – It’s needed for soaking some parts into the bowl and running water for rinsing the coffee grinder parts.

How to clean a manual coffee grinder

Cleaning your coffee grinder should not be neglected.

Not all coffee grinders are the same. But here is a simple step that can help you clean your coffee grinder.

Disassemble your coffee grinder

Before doing a deep cleaning, all hand grinders should be properly disassembled.

If you are unfamiliar with and not careful with dismantling coffee grinders, you may accidentally damage them or lose some of their parts.

That being said, you should consult the manual for the correct way to disassemble your grinder for your model. But basically, the things that require cleaning are:

  • The bean hopper
  • The hopper lid
  • The outer and inner burr
  • The grinds container

It would be best to take the parts apart on a flat surface with a white or plain towel under the grinder.

That way, the tiny parts, like the plastic and metal washer, would be visible, preventing them from getting lost.

Cleaning the burr coffee grinder/blade coffee grinder

The burr of a burr coffee grinder usually does most of the job. It turns coffee beans into freshly ground coffee beans. You have to make sure that they are well-cleaned.

  • Remove the lower section of the grinder and then pull out the conical burr set. To remove the burr pieces, you may need to use a tool. But on most coffee grinders, you can remove either the inner, outer burr or both. When disassembling the burr, remove only the components that are supposed to come off. Because each grinder is different, it’s best to consult the manual.
  • Using a soft and dry brush or toothbrush, clean the inside of the burr on all sides, or gently tap it on a cloth as a ground catcher to ensure no remaining traces of coffee. Brushing and cleaning them thoroughly is essential to ensure that no traces of coffee ground residue and oil buildup remain on the burr, making it harder for your grinder to produce even coffee grounds.
  • For areas that even the soft brush cannot reach, use a wooden toothpick can be a great help to remove coffee stuck in the burr’s crevices 
  • Put warm water in a large bowl, then soak the plastic or ceramic pieces of the burr.
  • Brush them using dishwashing liquid for thorough cleaning. Quickly rinse them in running water.
  • Make sure all the coffee beans burr pieces are thoroughly dried using a dry cloth or air-drying
  • Assemble the burr parts right away once they’re all dry

Avoid washing the metal or steel parts with water, as this can eventually create rust. Use a dry brush only.

Hand cleaning the hopper

Clean every corner of the grinder.

Because hoppers and lids are typically made of plastic or glass:

  • Brush them with soapy water to remove any remaining coffee particles, coffee dust, and oil residue.
  • Rinse it with water
  • Wipe it down with a dry cloth or paper towel
  • Let all the components dry completely before storing

Cleaning coffee grinders container

Cleaning coffee grinders container is the fastest and easiest step. You have to wash them using soapy water or mild dish soap. Scrub it lightly using a damp cloth or a soft brush.

Rinse well, then dry it thoroughly using a dry towel.

Reassembling the Manual Grinder

You can now reassemble the coffee grinder once every component has been thoroughly cleaned and dried. Are you worried about reassembling it incorrectly after cleaning?

You don’t need to worry! Putting them back together is less complicated than an electric grinder. Here’s a simple cleaning guide for your hand coffee grinder.

Basically, the first thing that you need to do is:

  • Insert the metal rod back through the top of the coffee grinder. Then there’s the plastic washer, the spring (it could go either way), and the metal washer; insert them into the metal rod. 
  • You can now carefully insert the burr pieces into the body. 
  • Lastly, put the grinds container back. 

You can now start grinding again. Enjoy your clean manual grinder!

Should I use Pellets?

You don’t always need to use grinder cleaning pellets, especially if it’s light burr cleaning. But simply using a brush won’t remove the residues. So when you notice uneven grounds and feel that there’s a rancid taste in your supposedly fresh brewing coffee, those are just some signs that you need to do a bit deeper cleaning of your grinder.

Is rice a good substitute for pellets?

Yes, some people use raw rice as an alternative for cleaning since it’s readily available at home. But because rice is harder than pellets, using it for cleaning could shorten the grinder’s lifespan, so many still prefer using pellets.
