How to Clean Your Grinder

Learn how to clean your coffee grinder or espresso grinder following the simple steps below. The easiest way is using Urnex Grindz. But we'll show you how to clean it manually as well.

Cleaning your Grinder with Grindz

The easiest way to clean a grinder is to run Grindz through it every couple of months. The following is from our partners at Urnex:

Before using Grindz, make sure to empty your hopper of any old coffee and adjust your grind 3 to 4 steps coarser.

  1. Add 1 packet (35 grams) of grinder cleaner tablets into empty grinder.
  2. Grind the whole package through your grinder and discard.
  3. Add 40 grams or 4-5 tablespoons of old coffee to your hopper.
  4. Grind the coffee to help push through any Grindz left in the burrs and discard.

Cleaning your coffee or espresso grinder without Grindz:

Recommend Tools:

  • 1 can of compressed air
  • 1 vacuum with nozzle attachment (optional)
  • 1 brush
  • 1 clean, dry towel
  1. Remove the hopper and empty it of any whole bean coffee.
  2. Use a clean, dry towel to wipe out the inside of the hopper. Avoid using a damp towel–any extra moisture in the grinder can cause ground coffee to stick to the burrs, resulting in jams and stalls.
  3. Use compressed air and a brush to clear any coffee in the burrs and grind chute. We recommend covering the top of the grinder with a towel to minimize coffee spraying into the air.
  4. If you have a vacuum with a nozzle attachment, use it to clean any loose coffee from the burrs, chute and counter.
  5. Replace the hopper and open the hopper throat.
  6. Enjoy your freshly cleaned grinder!
