Espresso Parts Espresso Machine Cleaner by Puro Caff top-brands/chemex but is not a universalThe Espresso Parts, Espresso Machine Cleaner is a specially designed backflush cleaner for espresso machines. Also known as Puro, we thought it was so good, that we put our name on it as well. 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.
