What is the recommended method for cleaning espresso machines?

The recommended method for cleaning espresso machines is to use a backflush technique with a cleaning solution. This method is essential because it effectively removes coffee oils, residue, and other build-up that can affect the taste of espresso and the function of the machine. Backflushing involves running a cleaning solution through the brew group, which helps maintain the machine's internal components in optimal condition by ensuring that the channels and filters are free of obstruction.

Regular cleaning through backflushing not only preserves the machine's performance but also extends its lifespan. It is a more thorough approach compared to simply wiping it down or soaking it in solutions. While other methods like rinsing the machine with hot water or using vinegar may have their place in different cleaning scenarios, they do not address the internal cleaning needs specific to espresso machines. Therefore, sticking to the backflush method is critical for ensuring high-quality espresso consistently.
