How do I clean and maintain my portafilter?

After each use: knock out the puck, rinse the basket under hot water, and wipe the portafilter with a dry cloth. Weekly: soak the basket in hot water with Cafiza powder for 20–30 minutes, scrub with a stiff brush, and rinse thoroughly. Inspect the gasket on the portafilter's handle join for cracks. Never put the portafilter in the dishwasher — the detergent strips protective oils. A clean portafilter basket is essential for even water distribution through the puck.
