In the 19th century, many cafes in Europe relied on steam equipment to speed up brewing and increase production.

Rinse the gasket out and then run it again until the water runs clear. Mix espresso machine cleaner with water in a container following the directions of the manufacturer at least once a week or as needed. Then soak the portafilters gratings, and baskets overnight in the cleaning solution. If your espresso maker comes with a steam wand or screen, take them out of the set using a screwdriver. In separate soaking, soak them in the cleaning solution.
