I have no idea what the "correct" terminology is (I would suppose that it has a name in the manufacturing industry, but I have worked as a barista and never known a specific name!) but I am refering to the actual rubber centre ring that makes contact with the group handle (thank you Andy for breaking bad habits!).
I have just (as in 2 hours ago) purchased my long lusted after Giotto Premium Plus and Mazzer Mini combo from Chris at Talk Coffee.
After setting everything up and letting the Giotto warm up, I pulled my Grindenstein down off the shelf to find that the rubber part has become disturbingly sticky!
First off, what might have caused this? It has been in storage for at least a year (in pantry/cupboard that is) where it has been out of sunlight but not exposed to moisture.
Secondly and *far* more importantly, does this present any risk to my new shiny baby? Could the "melted"/sticky rubber transfer to the group handle and damage the machine internals?

), do you notice any rubber come off onto to filter basket. If so, just wipe it off before preparing your next shot. .
