REI89 steam-assisted brew group brush - Cleaning Steam Brush
You clean your brew group and the shower sieve with steam and pressure.
You simply put the coupling on your steam pipe.
The system fits all steam pipes so far, from e.g. Quick Mill, La Pavoni Electra.
You put the coupling on the steam pipe. Because of the soft material
the system is immediately closed. Then the steam valve is turned on, the steam
rushes through the hose to the brush. You then clean with a brush and steam/pressure.
It works great!
