Cafetto Evo Espresso Machine cleaner is a must have to clean and back flush your espresso machine. It is BFA registered as complying with the Australian Standards for use with organic products. Cafetto Evo = clean machine = good espresso.
Backflush all visible coffee grinds
One spoonful in the blind filter (has no holes)
Carefully add boiling water and place handle into machine head
Leave at least 5 mins to allow the chemical cleaner to strip the coffee oil build up. Immediate backflushing will not allow time to dissolve the rancid oils.
Water back flush 7 to 10 times to clean away all the coffee oils and chemical and run a seasoning shot of espresso before use
We recommend this practice be done daily or twice daily in high use environments at the end of service with commercial machines & weekly with domestic machines. It is not how many coffees that make a machine head dirty but how long the coffee oils are left to go hard beneath the machine head. Coffee Lab New Zealand Facebook page has a step by step photo demonstrration of this process in the photos section.
