Rubber Blank Disc

A small rubber disc used to back flush your espresso machine

Place the rubber blank in the group handle, pour half a teaspoon of the Cleaning Powder on top and set the machine to back flush. This will clear the pipes and make sure there isnt any coffee residue left over.

Then use a cleaning brush to clear away any excess coffee left in and around the group head
