Learn the step-by-step process to clean your commercial coffee brewer using Urnex Cafiza. Remove coffee oils and residue to maintain flavor and equipment performance.
Quick answer
Use Urnex Cafiza Espresso Machine Cleaner to remove coffee oils and residue from your coffee brewer. Follow a simple soak-and-rinse cycle to keep your equipment performing at specification.
Why clean with Cafiza instead of plain water?
Coffee oils, milk residue, and mineral scale degrade flavor and damage equipment over time. Plain water rinsing cannot dissolve the baked-on coffee oils that accumulate on brew baskets, spray heads, and internal lines. Urnex Cafiza is purpose-formulated for coffee oil and residue removal, safe for group heads, portafilters, and baskets — it breaks down the buildup that water alone leaves behind.
When to clean your brewer
For commercial brewers, a thorough chemical cleaning should happen at least once per month, or more often if you brew multiple batches daily. Signs that cleaning is overdue include slower brew cycles, off flavors in the coffee, visible brown residue on the spray head, or inconsistent water temperature.
Step-by-step cleaning process
- Prepare the cleaning solution: Fill your brewer's water reservoir with fresh cold water. Add the recommended dose of Urnex Cafiza powder (typically 1 tablespoon per gallon of water, but check the label for your specific brewer capacity). Stir gently to dissolve. Do not use hot water to mix — it can cause the powder to foam excessively and reduce cleaning effectiveness.
- Run a brew cycle without coffee: Place an empty brew basket (or a cleaning basket if your brewer has one) under the spray head. Start a brew cycle so the Cafiza solution flows through the internal lines and into the basket. Let the solution sit in the basket for 5–10 minutes to loosen residue. Never run Cafiza through a coffee-filled basket — it will contaminate the coffee and waste the cleaner.
- Scrub and rinse the brew basket: After the soak, scrub the brew basket, spray head, and any removable parts with a non-abrasive brush. Then run two full cycles of fresh cold water through the brewer to flush out all chemical residue. If you still see brown residue after rinsing, repeat the entire process — one pass may not be enough for heavily soiled equipment.
