Urnex Cafiza Espresso Machine Cleaner

The frequency depends on your usage, but a general rule is to back-flush your machine once a week or every 50–100 shots. Regular maintenance prevents the buildup of coffee oils that can turn rancid and affect the flavor of your espresso.

Cafiza is specifically formulated for back-flushing group heads and soaking metal components like portafilters and filter baskets. It is not intended for use on plastic, rubber, or non-metal surfaces, so be sure to rinse those parts thoroughly if they come into contact with the solution.

Yes, Cafiza is NSF certified for metal compatibility, meaning it is safe to use on stainless steel. It effectively breaks down stubborn coffee residue and mineral scales without damaging the metal finish.

Dissolve a small amount of the concentrated cleaner in hot water and submerge your metal portafilter baskets for 15 to 30 minutes. Afterward, rinse them thoroughly under running water to ensure no residue remains before your next brew.

No, Cafiza is designed to be completely residue-free when rinsed properly. As long as you follow the back-flushing or soaking instructions with a thorough final rinse, your machine will be clean and ready for your next shot without any lingering aftertaste.
