Espresso Machine Cleaner is a specially designed backflush cleaner for espresso machines. Also known as Puro.

Here is how it works. The Puro espresso machine cleaner removes the residual build-up of coffee solids and oils from screens, valves, and tubes of brewing groups. This is important to quality coffee because a dirty machine will create dirty-tasting coffee. Backflush your machine following the directions on the label, and soak the portafilters (Not the Handles!) in a solution of very hot water and Puro.

Thoroughly rinse groups and portafilters. Always re-season your machine and portafilters by making and discarding one espresso on each group. Espresso machines should be cleaned daily.
