A crucial tool for maintaining your espresso machine is the blind filter, which is used along with espresso cleaning powder to clean and flush the machine. To back flush your machine: Remove the filter basket from the portafilter. Insert the blind filter into your portafilter. Add the high-quality Cafetto Evo powder, which is identifiable by its green color. Follow the recommended instructions for cleaning the machine. The blind filter is compatible with any standard 58mm portafilter.
