The most important thing to remember when you are cleaning your coffee grinder is to NOT use any liquids. Never pour water or liquid soap in your coffee grinder. Don’t even use a damp cloth to wipe down internal components. Any moisture in your burrs will attract coffee grounds. This can gum up your grinder, even breeding mould and bacteria. Burr grinders need to be dry cleaned only. 🙂
What You'll Need
1. A small, soft brush
We use a small paintbrush. You will use this to brush the coffee grinds off the burrs themselves as well as the grinds chute.
2. A cloth
Any soft, dry cloth will do to clean your coffee grinder.
3. Grinder cleaning tablets
4. Old coffee beans
Finally! A use for those old or stale beans you have lying around.
How to Clean Your Coffee Grinder
Step 1. Unplug and empty
Step 2: Clean
Step 3: Grindz
Measure out and put 1 capful of Urnex Grindz in the hopper of your grinder. Leave the coarseness setting at what you usually grind your coffee at, and grind the Grindz. Don’t let the noise surprise you. It will sound like you’re grinding your coffee beans.
The Urnex Grindz absorbs the excess oils that may remain on your grinder and in your burrs. The build-up of oils in a grinder is normal, but you want to remove that buildup regularly. The removal of these old oils helps to keep your coffee tasting as fresh as possible. If it’s been a while since you’ve cleaned your coffee grinder (or never!) you’ll definitely notice a difference in your coffee’s flavour.
4. Grind coffee
Now that you’ve removed the oils, run 2 caps of your old beans through your grinder.
FAQs about cleaning your coffee grinder
Can I use soap and water to clean my burr grinder?
No. Never use any liquid to clean the internal components of your coffee grinder.
Can I clean my burr grinder with rice?
Yes. You can substitute Urnex Grindz with a cup of uncooked rice, but you may want to be cautious. Rice is harder than Urnex Grindz, and even harder than coffee beans. Depending on the age and quality of your machine you may wear out the motor faster using this method. For this reason we always recommend using the proper cleaners for the job.
Is my burr grinder dishwasher safe?
No. Do not wash your burr coffee grinder with any liquid. First, if it’s an electrical appliance, your dishwasher will destroy it. Second, regardless if it’s manual or electric, you will gum up your burrs and affect their finish. These will have a bad effect on the flavour of your coffee and the life span of your coffee grinder.
How often should I clean my coffee grinder?
You should clean your grinder in this way about once a month, or as needed.
What is the best brush to clean my burr coffee grinder with?
We use a small, soft paint brush for cleaning coffee grinders.
