Espazzola is the new and innovative cleaning tool for the group head.
Specific for groups with 53-58 showers, Espazzola reaches every part of the group easily thanks to his its silicon membrane (3384017 or 3384018), a sort of brush designed to lock-in like your normal portafilter.
Effective and easy to use Espazzola cleans gently, preserving your gaskets and removing all the coffee debris.
It can also be used without coffee detergents.
How it works:
1) Insert the tool in the group head
2) Run some water through the group
3) Give the handle 5-10 wiggles back and forth
4) Turn the water off and let everything drain
