Urnex Cafiza 566 gr
This Urnex powder gets you out of the closet when you go blind filtering the espresso machine after the bar shift.
Every day you put a little bit of powder in your blind filter and then push the back flush buttons. Do not forget to rinse well.
In our opinion, the best stuff on the market and also usable to make all sorts of other cleaning and scrubbing work easier in the kitchen.
