Espresso Coffee Grinder Cleaning

Why?

Regularly cleaning your espresso coffee grinder’s bean hopper, doser, chute, and grinding burrs is crucial. This practice extends the grinder’s lifespan, enhances its performance, reduces downtime, improves the flavor of your espresso, and can save you from costly repairs in the future.

Bean Hopper Cleaning

If your beans are oily on their surfaces, these oils will accumulate onto the inside of your bean hopper. These oils can build up and disturb the flow of beans going into the neck of the grinding chamber. Therefore, we recommend cleaning the bean hopper on your grinder with a microfiber cloth.

The bean hopper should be removed MINIMUM ONCE EVERY MONTH for cleaning of the lower chute that enters the grinding chamber.

Doser Cleaning / Doserless Chute Cleaning

The doser on your doser model coffee grinder and/or the exit chute can retain ground coffee – especially if there is static, oily, or compacted ground coffee.

We recommending these items be cleaned MINIMUM ONCE EVERY MONTH.

  • The first step is using a brush to clean the coffee chute of any retained ground coffee.
  • The second step is to wipe the coffee chute (inside where possible and outside) with a microfiber cloth.

Grinding Burr Cleaning – Stand Alone (Not to Be Used on Super-Automatics)

For over 10 years, we would recommend that customers take apart their grinders to gain access to cleaning their burrs. The problem was always putting the grinder back together. Now, thanks to Puly Grind Crystals, we have a fantastic product, made in Italy, that performs extremely well in keeping those grinding burrs clean without taking apart the grinder!

After the coffee beans have been cleared from the bean hopper (and doser, if applicable), load the grinder cleaner into the bean hopper and grind just like you are grinding coffee beans. After grinding the entire amount, coffee beans should be ground to clear any cleaning residue from the grinding chamber. Clean the doser or doserless chute and you’re finished. This is much simpler than taking apart the coffee grinder.  Review our Puly Grind Crystals video.

Grinding burrs should be cleaned at least EVERY 6 MONTHS or whenever there is a problem attaining a fine enough grind fineness.
