8. Cleaning
8.1 Cleaning with GRINDZ™ Grinder Cleaner
We recommend cleaning your espresso grinder once a week and
your shop grinder once a month with our GRINDZ™ Grinder
Cleaner.
Simply take the recommended dose (35 - 40g for espresso
grinders and 70-80g for shop grinders) and drop it into an 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.
