What is daily vs weekly espresso machine cleaning?

Daily: wipe the steam wand immediately after use, knock out the puck, rinse the portafilter, and run a blank shot of plain water through the group head. Weekly: backflush with Cafiza, clean the portafilter basket with a soak, wipe down the drip tray, and purge steam wand thoroughly. Monthly: deep clean the group head gasket and shower screen. Consistent cleaning prevents bitter coffee oils from building up and extends machine life significantly.
