Puro Caff by Urnex is a professional-grade espresso machine cleaning powder in a 20 oz (566 g) jar. NSF-certified and odorless, it is formulated specifically for espresso machines to remove residual coffee oils and solids from groupheads, valves, lines, and screens, keeping filters clear for consistent, even extraction. Each jar provides over 150 cleaning cycles, making it economical for both home use and commercial settings. Product code 18-P20.

The powder is designed for daily use via the backflush method. Insert a blind filter into the portafilter, add up to 1/2 teaspoon (approximately 3 g) of powder, and run alternating 10-second brew and stop cycles — typically five times — then rinse thoroughly without cleaner and repeat. The same solution can be used to soak portafilters, filter baskets, screens, and other removable parts. The formula dissolves cleanly and leaves no unwanted odor or residue, making it an essential component of routine espresso machine maintenance.
