9.1 Cleaning with GRINDZ™ Grinder Cleaner

We recommend cleaning your shop grinder once a month with our 

GRINDZ™ Grinder Cleaner.

Simply take the recommended dose of 70 - 80g for shop grinders and 

drop it into the empty grinder hopper. You can also use the cup of the jar 

for dosing. A full cup will yield between 35 - 40 grams. 

Adjust machine setting to medium and operate as if grinding coffee 

beans. Once complete, we recommend passing twice as much coffee 

through to purge any residue.

9.2 Cleaning the grinder casing

Clean the casing of your grinder every now and then with commercially 

available mild cleaning agents. In addition, you should also clean the 

magnet in the hopper from time to time by removing any foreign ob-

jects that may have become stuck because otherwise this could result 

in clogging.

Do not let any foreign objects fall into the grinding 

mechanism!!
