Urnex Cafiza Espresso Machine Cleaner

Last updated: October 2, 2026

What Cafiza Actually Does

Urnex Cafiza is a backflushing detergent — a powdered cleaner designed to strip coffee oils and residue out of the group head, three-way solenoid valve, and portafilter internals of an espresso machine. It’s not a descaler. That’s the single most common point of confusion, and getting it wrong means either buying the wrong product or running the wrong procedure through your machine.

Coffee oils are the problem Cafiza solves. Every shot leaves a film of lipids and fine particles behind the shower screen and inside the valve that exhausts pressure after you stop the pump. Those oils go rancid in days, and rancid oil tastes like stale, ashy bitterness layered on top of whatever bean you’re using. A water backflush flushes the pathway but doesn’t dissolve oil. Cafiza does — it’s an alkaline detergent built around sodium carbonate and surfactants, roughly the same idea as espresso-specific cleaners from other brands.

If your machine has a three-way solenoid valve — which includes most semi-automatic machines like the Gaggia Classic, Rancilio Silvia, Breville Dual Boiler, and every E61 machine — Cafiza (or an equivalent detergent) is essentially mandatory maintenance. Machines without a solenoid, like the Breville Barista Express’s cheaper siblings or most superautomatics, can’t be backflushed at all. Forcing detergent through a machine that can’t backflush can trap chemical residue in the brew path, so check your manual before buying.

Superautomatic owners get a different version of the same product: Urnex sells Cafiza in tablet form for machines that run automated cleaning cycles through the brew unit.

How to Use It

For a weekly backflush on a solenoid-equipped machine:

• Insert a blind (solid) basket into the portafilter.
• Add about half a teaspoon of Cafiza powder.
• Lock it in and run the pump for 10 seconds, then stop. The valve will spit dirty water into the drip tray.
• Repeat 4-5 times until the exhausted water runs clean.
• Remove the portafilter, rinse, then run several more cycles with water only to flush all detergent out.

The powder also works for soaking portafilters, baskets, and screens — dissolve a teaspoon in hot water, soak 15-30 minutes, rinse thoroughly. It lifts the brown film that a sponge won’t touch.

One caution: Cafiza is aggressive on aluminum. Don’t soak aluminum portafilter handles or moka pots in it — it discolors and pits the surface. Keep it to stainless and brass parts.

Which Size to Buy

The powder comes in three common formats. The math matters more than the branding:

The big jar is objectively the best value — half a teaspoon per weekly backflush means it lasts a year or more, and the powder doesn’t expire in any meaningful way if kept dry. The catch is that many households only need a small jar; a 20 oz tub is only worth it if you’ll actually backflush weekly for years. Tablets cost several times more per dose but eliminate the guesswork, which matters if the machine’s manual specifies a tablet cycle.

Cafiza vs. Alternatives

Cafiza’s main competition is generic espresso machine detergent and a few branded rivals like Puly Caff and Joe Glo. In practice, they all work. The chemistry is similar across brands, and blind side-by-side testing reveals no meaningful difference in cleaning power when used correctly. Puly Caff is slightly cheaper in some markets and is the default in many European cafés.

What about DIY substitutes? Some people use OxiClean or baking soda. Skip this. Oxygen bleach works in a pinch for soaking baskets, but it’s not formulated or certified for food-contact backflushing, and residue risk isn’t worth saving $8 a year. Baking soda doesn’t cut coffee oil effectively at all.

If you want a cheaper equivalent that’s still purpose-made, generic espresso backflush detergent usually costs 20-30% less than Cafiza and performs identically for home use. Cafiza’s real advantage is availability, consistent dosing, and that it’s what most machine manuals name-check.

Don’t Forget the Other Half of Maintenance

Cafiza handles oil; it does nothing about scale. If you have hard water and a boiler, you still need a descaler on whatever schedule your water hardness and machine dictate — typically every 1-3 months. Cafiza for weekly backflushing, an espresso machine descaler periodically, and your machine stays clean on both fronts. Many owners buy one and neglect the other; the most common failure is immaculate group heads paired with a scaled boiler, or vice versa.

Common Mistakes and Failure Modes

Using too much powder. More isn’t cleaner — it just takes longer to rinse out. Half a teaspoon is enough.

Backflushing a machine without a solenoid. Covered above, but it bears repeating: no valve means the detergent has nowhere to go except places it shouldn’t.

Skipping the water-only rinse cycles. Detergent residue in your next shot tastes soapy and defeats the purpose. Run at least five blank cycles after the last Cafiza cycle.

Soaking aluminum parts. Discoloration is cosmetic but permanent on anodized finishes.

FAQ

Is Cafiza the same as a descaler?

No. Cafiza removes coffee oils from the brew path. Descalers remove mineral scale from boilers and water lines. Most espresso machines need both, on different schedules.

How often should I backflush with Cafiza?

Weekly is the standard recommendation for daily-use machines. Light users can stretch to every two weeks; heavy use (multiple shots daily) benefits from twice weekly.

Can I use Cafiza in a superautomatic like a Jura or De’Longhi?

Use the tablet version, not the loose powder. Run it through the machine’s automated cleaning cycle per the manual. Don’t pour powder into the brew unit.

Is generic backflush detergent as good as Cafiza?

For home use, yes. The chemistry is nearly identical across brands. Cafiza costs a bit more but is easier to find and is the name most manuals reference.
