☕ Buying Guides · 2026A cleaner removes coffee oil; a descaler removes scale; they are different chemistry and both are needed. Which cleaner for which machine - backflush powders and tablets, Breville's cleaning-cycle tablets, grinder tablets and milk-system cleaner - from the makers' own instructions and fourteen verified listings.

Two things build up inside an espresso machine and they need two different products. Coffee oil and grounds collect in the group head, the shower screen, the valve and the baskets, turn rancid within days, and make every shot taste bitter and flat; an espresso machine cleaner - Cafiza, Puro Caff, Puly Caff, or the maker's own tablets - is an alkaline detergent that dissolves them. Limescale forms from the minerals in water on the heating element and inside the boiler; a descaler is an acid that dissolves that, and no cleaner will. For a machine with a three-way valve - most prosumer and E61 machines - the cleaner is used in a backflush with a blind basket. For a Breville, the instruction book prescribes a cleaning cycle with a cleaning disc and tablet instead. The grinder needs its own tablets, and a steam wand needs a milk-protein cleaner. Buy the cleaner your manual names, then a descaler, then the grinder tablets.
The confusion that sends people to the wrong bottle is that both products are sold as coffee machine cleaner. They do opposite jobs. Every shot leaves coffee oil on the shower screen, in the group head, on the gasket and inside the three-way valve that vents the puck after the shot; oils oxidise and go rancid within days, and old grounds packed in the screen block holes and skew the extraction. An espresso machine cleaner is an alkaline detergent built to dissolve those oils - Urnex describes Cafiza as eliminating coffee residue and oils from group heads, valves and lines and keeping screens and filters clear for even extraction, and the Puro Caff and Puly Caff listings say the same in their own words. It does nothing to scale. Scale is calcium and magnesium carbonate left behind when water is heated, and it coats the element and the inside of the boiler until the machine heats slowly, drips from the group, or stops; a descaler is an acid that dissolves it, and Urnex's Dezcal listing describes exactly that, with a dose of 1 oz of powder per 32 oz of reservoir. It does nothing to coffee oil. Urnex even sells its milk cleaner in an alkaline formula and an acid formula for different automatic milk systems, which is the clearest illustration that the two chemistries are not interchangeable.
So a machine needs both, on different schedules. Coffee oil is a matter of shots: cafes backflush daily, and a home machine pulling two or three shots a day is cleaned weekly. Scale is a matter of water: hard water needs descaling every month or two, filtered or soft water every few months, and a machine on a good filter may need it rarely. The three descaling guides on this site - for Breville, Nespresso and Keurig machines - cover that side. This page is about the other one.
Backflushing is the cafe method and it depends on one part: a three-way solenoid valve that opens to the drip tray when the pump stops, which is what releases pressure from the puck. Put a blind basket - a basket with no holes, also sold as a backflush insert or disc - in the portafilter, add the cleaner, lock it in and run the pump for a few seconds. With nowhere to go, the water and detergent are forced back up through the shower screen and the valve, and when the pump stops the valve dumps the dirty solution into the tray. Urnex's instructions for Cafiza powder: insert the blind filter, add up to half a teaspoon (3 g) of powder, and run the cycle; then repeat with clean water until it runs clear. Tablets do the same job in a pre-measured form - Cafiza tablets, or the small 1.5 g Cafetto Tevo Mini tablets whose listing names Breville, Sage, Gaggia, Rancilio, Rocket, ECM, Profitec and Lelit as compatible machines. The Puro Caff listing calls the daily backflush integral to traditional espresso machines, and that is the class this method belongs to: E61 and prosumer machines with a solenoid valve, which includes every heat exchanger and dual boiler on our boiler types guide.
Two cautions. If your manual has no backflush procedure, do not backflush; a machine without a three-way valve has nowhere to send the pressure. And backflush with detergent only as often as the manual says - many makers specify water-only backflushes daily and detergent weekly - because the alkaline solution that strips coffee oil also strips the lubricant from the group's moving parts if overused. The same powders double as a soak: Urnex's dose is 6 g per litre of hot water, parts in for 30 minutes, then rinse. Soak the portafilter, baskets, shower screen and the drip tray grate; the brush on this page reaches the gasket groove and the screen in place, and its handle has a scoop for the powder. Cafiza powder and tablets are NSF certified and OMRI listed per their listings.
Breville's home machines do not backflush in the cafe sense; their instruction books, quoted on our Breville descaling guide, prescribe a cleaning cycle: a rubber cleaning disc goes into the single-cup basket, a cleaning tablet goes on the disc, the portafilter locks in and the machine runs its own programmed cycle when the CLEAN alert shows. The machine still has a valve that vents to the tray, which is why the cycle works, but the dose, the timing and the alert are the machine's own, and the tablet is sized for them. Breville's BEC250 tablets state on their listing that they remove coffee oils and residues from the shower screen and filter baskets, suit all Breville espresso machines and are non-corrosive. The Cafetto Tevo Mini tablet, at 1.5 g, is the third-party alternative that names Breville and Sage among its compatible machines, and it also fits a blind basket on a traditional machine, so it is the one tablet that serves both kinds of household. Machines without any cycle or valve - most entry thermoblock machines - are cleaned by soaking the removable parts in the same powders and wiping the group with the brush.
Drip machines and pod brewers have their own product. Urnex's Cleancaf is run through like a pot of coffee and its listing states it removes residual coffee oils and buildup and gently removes lime scale in automatic coffee makers, which makes it the one product on this page that touches both problems, at the gentle end of each; our coffee maker cleaning guide covers the full routine for drip machines.
The grinder collects the same oils, plus fine grounds packed into the burr chamber, and a dirty grinder drifts finer and tastes stale. Grinder cleaning tablets are the fix that needs no disassembly: Urnex's Grindz are made from plant-based ingredients, and Urnex's instructions are to use one jar cap (35 to 40 g) for an espresso grinder, run it through at a medium setting, then repeat with coffee beans to purge the residue. The listing and Urnex's page both carry the one hard rule: do not use Grindz in the integrated grinder of a super-automatic machine; Urnex makes SuperGrindz for those. The Full Circle grinder tablets in three single-use packets are the way to try the method, and both listings note the tablets also prevent flavour transfer when switching between regular, decaf and flavoured beans. Brush the burrs and the chute when you clean, and for hand grinders, which take tablets less well, a brush and a dry cloth do most of the work; the makers' own guidance for each grinder is linked from our espresso grind size guide.
Milk is the third residue and the one that turns fastest. A steam wand that is not purged and wiped after every use bakes milk protein onto the tip and inside the wand, and an automatic frother grows it in the tubing. Urnex's Rinza in the alkaline formula, per its listing, breaks down milk protein buildup, cleans traditional steam wands and steel pitchers, cycles through automatic frothers, and measures itself from a dual-chamber bottle for over 30 uses; soak the wand tip in the solution, run the frother's cycle with it, and rinse. Our milk frothing guide covers the purge-and-wipe habit that makes the deep clean rare.
E61, heat exchanger or dual boiler with a three-way valve: Cafiza powder (or Puro Caff or Puly Caff), a blind basket, the group brush, and weekly detergent backflushes with daily water ones - plus a descaler on your water's schedule. A Breville: BEC250 tablets or the Cafetto Tevo Mini for the cleaning cycle, Breville's descaler for the descale alert, and the powder for soaking baskets. An entry machine with no cycle: soak the removable parts in Cafiza or Puly Caff, brush the group, descale on schedule. Any grinder that is not inside a super-automatic: Grindz or the Full Circle packets, then a purge with beans. A super-automatic: the maker's own tablets and its own descaler, and SuperGrindz rather than Grindz for the grinder. Milk drinks: Rinza for the wand, the pitcher and the auto-frother. A drip machine or pod brewer: Cleancaf through the brew cycle, or the routine on our coffee maker cleaning guide. The accessories that make the routine painless - knock box, tamping mat, cloths - are on the espresso machine accessories guide.

Check price on Amazon →A cleaner is an alkaline detergent that dissolves coffee oil and grounds from the group head, screen, valve and baskets. A descaler is an acid that dissolves limescale left by water minerals on the heating element and boiler. Each does nothing for the other problem, so a machine needs both.
For a machine with a three-way valve, Urnex Cafiza is the cafe standard: NSF certified, used at up to half a teaspoon (3 g) per backflush or 6 g per litre as a soak, per Urnex. Puro Caff and Puly Caff do the same job. For a Breville, the tablets its instruction book names - BEC250, or the compatible Cafetto Tevo Mini.
Not in the cafe sense. Breville's instruction books prescribe a cleaning cycle: a cleaning disc and tablet in the single-cup basket, run when the CLEAN alert shows. Use the powders for soaking baskets and the screen; use the tablets for the cycle.
Coffee oil by shots, scale by water. A home machine pulling a few shots a day: a water backflush daily on machines that allow it and a detergent backflush or cleaning cycle weekly; soak the baskets and screen weekly; descale every month or two on hard water, less on filtered water.
Yes - the Cafiza listing states it suits home equipment as well as professional machines, and it is NSF certified and OMRI listed. Use it only on machines whose manual describes backflushing, and only at the manual's frequency, because an alkaline detergent also strips group lubricant if overused.
Grinder cleaning tablets. Urnex's instruction for Grindz is one jar cap (35-40 g) for an espresso grinder, run through at a medium setting, then a purge with coffee beans. Do not use them in the grinder of a super-automatic machine; Urnex makes SuperGrindz for those.
A milk-protein cleaner such as Urnex Rinza in the alkaline formula: its listing states it breaks down milk protein buildup and cleans traditional steam wands, steel pitchers and automatic frothers. Purging and wiping the wand after every use is what keeps that deep clean rare.
Vinegar is a weak descaler with a lingering smell and does nothing to coffee oil; the Dezcal listing describes its descaler as more effective and faster than vinegar. Dish soap leaves a film and a taste in the group. The purpose-made cleaner costs a few cents a use and is what the makers' manuals name.
