Using Cafiza to Clean Your Coffee Maker a Step By Step Guide
Cafiza is a professional-grade detergent made by Urnex, originally developed for commercial espresso machines. It breaks down coffee oil residue—that brown, sticky film that ordinary dish soap can’t touch—from your machine’s internal lines, heating element, and reservoir. You can use it in drip coffee makers, Keurig machines, and espresso machines, but the process differs by machine type.
Here’s what you need to know upfront: Cafiza removes coffee oils, not mineral scale. If your machine is brewing slowly or sputtering, you likely have hard-water buildup and need a descaling solution (like Urnex Dezcal or white vinegar) instead. For routine oil removal—every 1–3 months depending on usage—Cafiza is the right tool. The full process takes about 20 minutes, most of which is waiting for the solution to soak.
What Cafiza Does and What It Doesn’t
Cafiza is a powdered detergent that emulsifies coffee oils. Those oils oxidize over time and turn into a sticky residue that:
- Clings to internal tubing and heating elements
- Makes coffee taste bitter or stale
- Provides a breeding ground for bacteria and mold
- Can clog internal valves over time
The active ingredients are food-safe and rinse away completely with water. Cafiza is not a descaler—it won’t remove calcium or limescale. If you have hard water, you’ll need to descale separately. Many owners alternate: Cafiza for oil removal, then a descaling cycle every 3–6 months.
One important note: Cafiza is highly concentrated. One scoop (about 2 grams) is enough for a full cleaning cycle in most machines. Using more doesn’t clean better—it just means more rinse cycles to flush the residue.
Before You Start: Prep Checklist
Skip the prep and you’ll be dealing with a mess. Here’s what to do first:
1. Unplug the machine and let it cool completely if it’s been running
2. Remove and empty the carafe or thermal mug
3. Take out any reusable filters and rinse them separately
4. Remove the water reservoir if it’s detachable and empty it
5. Check your manual for manufacturer-specific cleaning instructions—some machines have a dedicated cleaning cycle button
For Keurig-style pod machines, also remove the pod holder and K-cup needle assembly if your model allows it. The needle that punctures the pods is a common spot for coffee residue to collect.
Cleaning a Drip Coffee Maker with Cafiza
This process works for standard drip machines like the Cuisinart Coffee Maker, Programmable, Stainless Steel, 14-Cup Glass Carafe or the Cuisinart 12-Cup Coffee Maker, Programmable PerfecTemp Thermal Carafe.
Step 1: Mix the Solution
Fill the reservoir with fresh water. Add one scoop (about 2 grams) of Cafiza powder directly into the reservoir. Stir briefly with a long spoon to help it dissolve—Cafiza dissolves quickly in warm water but takes longer in cold.
Step 2: Run a Partial Brew Cycle
Start the brew cycle but stop it halfway through. The goal is to get the solution into the internal lines and let it soak. If your machine has a “pause and serve” feature, use that to interrupt the cycle. Let the solution sit for 10–15 minutes. This dwell time is critical—it gives the detergent time to break down oils inside the heating element and tubing.
Step 3: Complete the Brew Cycle
Restart the brew cycle and let the remaining solution run through completely into the carafe. Discard the water.
Step 4: Rinse Cycle 1
Fill the reservoir with fresh water and run a full brew cycle. Discard. This flushes the bulk of the detergent from the system.
Step 5: Rinse Cycle 2
Repeat step 4. This second rinse is non-negotiable—Cafiza residue will make your next pot taste soapy if you skip it. If you have a sensitive palate or brew light roasts, a third rinse doesn’t hurt.
Step 6: Wipe Down the Exterior and Carafe
While the machine is rinsing, wipe down the warming plate, the carafe, and the lid with a damp cloth. The carafe can be washed with regular dish soap—Cafiza isn’t needed there.
Success check: Your next pot of coffee should taste clean—no bitter, stale, or soapy notes. If you still taste residue, run one more rinse cycle.
Cleaning a Keurig or Pod Machine with Cafiza
Keurig machines (K-Supreme, K-Elite, K-Mini, and similar models) need a slightly different approach because they dispense directly into your mug rather than a carafe.
Step 1: Prepare the Machine
Unplug the machine. Remove the water reservoir, the pod holder, and the K-cup funnel. Wash these parts with warm soapy water and set them aside to dry. This is also a good time to check the exit needle—the small needle at the bottom of the pod holder—for clogs.
Step 2: Mix the Solution
Fill the reservoir with fresh water and add one scoop of Cafiza. Swirl the reservoir to dissolve the powder.
Step 3: Run the Cleaning Cycle
Place a large mug or bowl (at least 12 ounces) on the drip tray. Run a brew cycle without inserting a pod. The machine will draw the Cafiza solution through the internal lines and out the exit needle. Stop the cycle halfway through and let it sit for 10–15 minutes.
Step 4: Complete the Cycle and Rinse
Restart and finish the brew cycle. Discard the liquid. Refill the reservoir with fresh water and run at least two full brew cycles (no pod) to rinse. The second rinse is where most people cut corners—don’t.
Step 5: Clean the Needle (If You Haven’t Recently)
While the machine is unplugged, use a paper clip to gently clear any coffee grounds stuck in the exit needle. This is a common failure point on Keurig machines. If your machine is running slow or not dispensing at all, a clogged needle is often the culprit.
Success check: Run a mug of plain hot water. If it tastes clean and flows at normal speed, you’re done.
The Counter-Intuitive Angle: Don’t Clean the Carafe with Cafiza
Most guides tell you to clean everything, but the carafe is the one place you should not use Cafiza. Here’s why: Cafiza is formulated to aggressively break down coffee oils. On glass carafes, it’s fine—but on thermal carafes with a metal interior, Cafiza can strip the seasoning that’s built up over time. That seasoning, while it sounds unappealing, actually helps your coffee taste consistent.
Wash the carafe with regular dish soap and a non-abrasive sponge. For stubborn stains, use a dedicated carafe cleaner or baking soda. Save the Cafiza for the machine’s internal lines, where it actually matters.
Areas People Miss and Why They Matter
Most cleaning guides stop after the brew cycle, but these three spots collect residue and cause problems later.
The Water Reservoir Lid and Gasket
The rubber gasket on the reservoir lid traps moisture and coffee splatter. If you don’t wipe it down, it grows mold that recontaminates your clean machine within days. Remove the gasket if possible and wash it with soapy water.
The Spray Head (Drip Machines)
The spray head—the small disc under the top lid that distributes water over the coffee grounds—clogs with coffee oils over time. On many machines, it’s removable. Soak it in a small bowl of Cafiza solution while you run the main cleaning cycle, then rinse thoroughly.
The Exit Needle (Pod Machines)
We mentioned this above, but it deserves emphasis: the exit needle on a Keurig is the #1 cause of slow brewing and weak coffee. A paper clip or a specialized cleaning tool clears it in seconds. Do this every time you clean with Cafiza, not just when you notice a problem.
How Often Should You Clean with Cafiza?
This depends on how much coffee you brew and how oily your beans are:
| Usage Level | Cleaning Frequency |
|---|---|
| 1–2 cups per day | Every 2–3 months |
| 3–4 cups per day | Every 4–6 weeks |
| 5+ cups per day or heavy use | Monthly |
| Dark roasts or oily beans | More frequently—dark roasts deposit more oil |
If your coffee starts tasting bitter, stale, or “off” before your scheduled cleaning, that’s your signal to clean sooner. Trust your taste buds over the calendar.
What Cafiza Won’t Fix and When to Escalate
Cafiza is a maintenance tool, not a repair tool. If your machine is exhibiting any of these symptoms, cleaning won’t solve the problem:
- Slow brewing or sputtering → Likely mineral scale. Use a descaler like Dezcal or a vinegar solution (1:1 vinegar to water) and run a full descaling cycle.
- Machine won’t turn on → Electrical issue. Check the power cord and outlet first; if those are fine, contact the manufacturer.
- Water leaks from the bottom → Could be a cracked reservoir, failed seal, or internal valve issue. This is a repair or replacement situation.
- Coffee tastes metallic → This is often a water quality issue, not a cleaning issue. Try filtered water.
When to escalate: If you’ve cleaned with Cafiza, descaled, and the machine still performs poorly, it’s likely time for a new machine. Most budget and mid-range coffee makers have a lifespan of 3–5 years with regular maintenance. If your machine is still under warranty, contact the manufacturer before attempting any disassembly beyond what the manual permits.
Frequently Asked Questions
Can I use Cafiza in a Keurig?
Yes. Cafiza is safe for Keurig machines and effectively removes coffee oil buildup. Run a brew cycle without a pod, let the solution sit for 10–15 minutes, then rinse with two full water-only cycles.
Is Cafiza safe for all coffee maker brands?
Cafiza is food-safe and safe for any coffee maker that uses water. However, always check your manufacturer’s manual for specific cleaning recommendations—some machines have proprietary cleaning solutions or cycles.
How is Cafiza different from vinegar?
Vinegar is a mild acid that dissolves mineral scale (calcium, limescale). Cafiza is a detergent that breaks down coffee oils. They solve different problems, and most machines need both over time—Cafiza for oil removal and a descaler for hard-water buildup.
Can I mix Cafiza with vinegar or descaling solution?
No. Never mix cleaning products. Run them as separate cycles—Cafiza first, then a descaling cycle if needed. Mixing them can create a reaction that damages internal components.
How much Cafiza should I use?
One scoop (about 2 grams) per full cleaning cycle. Using more doesn’t clean better—it just requires more rinse cycles to remove the residue.
Do I need to rinse after using Cafiza?
Yes, absolutely. Run at least two full water-only brew cycles after cleaning. Cafiza residue will make your coffee taste soapy if not fully flushed.
Cafiza is one of the most effective cleaning tools for coffee makers, but it’s not a universal solution. Use it for oil removal, pair it with regular descaling for hard water, and clean the parts most guides skip. Your coffee will taste noticeably cleaner, and your machine will last longer—that’s the payoff for 20 minutes of maintenance.
