Espresso mechanics 101. Cleaning shower screen

i would like to share some top tips for keeping your coffee machine clean. Most people may know to backwash the machine. Use a blind filter and run the pump. That cleans the water paths through the group. But this is pointless if the shower screen is clogged and dirty. Backwashing will not clear hardened oils.

There will be many machines out there that could benefit from this simple clean or replace item that will greatly improve your coffee.
