Urnex Cafiza is an espresso-machine detergent for removing coffee oils and residue. It is not a descaler: it will not remove mineral scale from a boiler or water circuit. The powder is a practical choice for owners of machines with a three-way solenoid valve and for cleaning compatible portafilter baskets, screens and other removable parts. Whether it is the right buy depends on your machine’s cleaning instructions and how you plan to use it.
Quick answer: Our top pick in 2026 is the Cafiza powder — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
What Cafiza does—and what it doesn’t
Espresso leaves oily residue in the group head, on the shower screen and inside the basket. Over time, that buildup can turn rancid and affect the taste of coffee. Cafiza is formulated to loosen and remove those coffee oils during a backflush or soak.
Scale is different: it is mineral buildup left by water. Cafiza does not dissolve it. For that job, use a descaler approved for your machine, and follow the manufacturer’s procedure. Using detergent in place of descaler—or descaler in place of detergent—won’t solve the underlying problem.

Cafiza makes most sense if you own a machine whose manual permits detergent backflushing. It also suits people who want one product for routine group cleaning and occasional soaks of compatible metal parts. A small jar is enough for home use; cafés and heavy users may prefer a larger container to avoid frequent reordering.
Skip backflushing if your machine’s manual says not to. Some machines lack the required valve, and forcing the procedure can send water where it shouldn’t go. For a basic machine that only calls for rinsing and brushing, detergent may be unnecessary—or the manufacturer may specify a different cleaner. Check the manual before buying.
How to use it without creating a new problem
For a backflush, use a blind basket and the dose and cycle specified by your machine’s instructions. Run the prescribed detergent cycles, then repeat with clean water until there is no visible foam or detergent residue. Don’t assume one quick rinse is enough: leftover cleaner can give the next shot an unpleasant soapy taste.
To soak a basket or other removable part, dissolve the powder in hot water and follow the product and machine instructions for concentration and soak time. Keep aluminum, painted surfaces, and parts with seals or coatings out of the solution unless their maker says they are compatible. Rinse thoroughly afterward. Avoid mixing Cafiza with other cleaners, and store the powder dry and closed.
Cafiza powder versus other cleaning options
| Option | Best for | Trade-off |
|---|---|---|
| Cafiza powder | Backflushing and soaking compatible parts | Needs measuring and careful rinsing; not a descaler |
| Espresso cleaning tablets | Owners who prefer a pre-portioned dose | Often cost more per use; confirm they suit your machine |
| Water and a group brush | Frequent light cleaning and machines that prohibit detergent backflushing | Won’t remove stubborn coffee oils as effectively as detergent |
| Espresso-machine descaler | Mineral scale, when the machine’s maker recommends descaling | Not a substitute for cleaning coffee oils; procedure varies by machine |
If measuring powder is a nuisance, compare espresso-machine cleaning tablets. They can simplify dosing, but aren’t automatically better or compatible with every machine. If your machine calls for detergent backflushing, Cafiza is a reasonable option; if it does not, a group-head brush and water may be the more appropriate routine purchase.
Practical trade-offs and common mistakes
Powder is usually economical and flexible: you can measure a small amount for a routine clean or prepare a soak. The trade-off is that it’s easy to use too much, spill it, or leave residue behind. Buying a large container only saves money if you’ll use it before storage conditions or age become an issue.
Another common mistake is treating a slower shot as proof that the machine needs descaling. A dirty basket or shower screen, a change in grind, or a clogged filter can also affect flow. Clean and inspect the parts first, then use the manufacturer’s descaling guidance if scale is suspected. Cafiza won’t fix worn seals, a failing pump, or a blocked water circuit.
For routine care, brush loose grounds from the group area and rinse the basket after use. Use detergent cleaning at the interval your machine maker recommends, rather than assuming more frequent chemical cleaning is always better. That keeps the task simple and reduces the chance of residue or damage from an incompatible soak.
Which format and size to choose
For a home machine used daily, a small container is a sensible starting point, especially if you’re not sure how often you’ll use detergent. Choose a larger size only if you backflush regularly, share it across machines, or clean equipment in a small café. If you already know you dislike measuring powder, tablets may be worth the higher per-use cost.
Before placing an order, check that the listing is for espresso-machine detergent, not descaler, and verify the package size. Keep the product in its original container so the label and handling directions stay available.
FAQ
Can I use Cafiza to descale my espresso machine?
No. Cafiza removes coffee oils and residue; it does not remove mineral scale. Use a machine-approved descaler for that task.
Can I backflush every espresso machine with Cafiza?
No. Backflushing is only appropriate for machines designed for it. Check the manual before using detergent or a blind basket.
Can I use Cafiza on a portafilter and basket?
Usually, compatible metal baskets and portafilters can be soaked, but check the manufacturer’s guidance and keep parts with uncertain coatings, seals, or materials out of the solution. Rinse thoroughly.
Is powder better than cleaning tablets?
Not for everyone. Powder is flexible and often economical; tablets make dosing easier. Choose based on your machine’s instructions and how much convenience matters to you.
