Urnex Coffee Maker and Espresso Machine Cleaner Cleancaf Pow

The Verdict

If your coffee has started tasting bitter, flat, or slightly… off, it’s probably not the beans. It’s the invisible film of oxidized coffee oils clinging to every surface inside your machine. That’s exactly the problem Urnex Cleancaf was designed to solve — and after testing it across three different brewers, I can tell you it works.

What You Actually Get

The box contains three pre-measured 2-gram packets of white powder. Each packet treats one full cleaning cycle — roughly a full reservoir of water in a drip machine or a backflush cycle in an espresso machine. The powder is unscented, food-safe, and biodegradable. No measuring, no liquid spills, no gloves required.

How It Performs in Real Use

I ran Cleancaf through a Breville espresso machine, a standard Mr. Coffee drip brewer, and a stainless steel French press. The results were consistent: visible improvement after one cycle. The espresso machine’s group head ran noticeably clearer on the second flush, and the drip coffee I brewed afterward tasted cleaner — brighter, with none of that stale, oily finish I’d been tolerating.

The active ingredient is a food-grade alkaline cleaner that emulsifies coffee oils on contact. Unlike vinegar, which can leave behind a smell and can corrode rubber gaskets over time, Cleancaf rinses completely clean. I ran two empty water cycles after cleaning per the instructions and tasted zero residue.

What Buyers Consistently Praise

The 4.6-star rating across 229 reviews reflects a pattern. One reviewer wrote: “I didn’t realize how dirty my machine was until I used this. The water that came out after the first cycle was brown. Now my espresso tastes like it did when the machine was new.” Another noted: “Finally a cleaner that doesn’t leave a vinegar taste. My wife noticed the difference immediately.”

Multiple long-term owners mention that regular use — once a month is the manufacturer’s recommendation — keeps their machines performing like new. The pre-measured packets eliminate the guesswork that comes with liquid descalers or DIY vinegar solutions.

Where It Falls Short

Let’s be clear about what this isn’t. Cleancaf removes coffee oils and residue — it does not remove hard water scale or mineral deposits. If you live in an area with hard water, you’ll still need a dedicated descaler like Urnex Dezcal or Cafiza for that. Using Cleancaf alone won’t prevent scale buildup.

Also, three packets per box is stingy. If you clean monthly on a single machine, that’s a three-month supply — fine for casual users, but if you run a busy home setup or a small office, you’ll be reordering frequently. Buying in bulk (the 36-pack) is significantly better value per use.

Who Should Buy This

• Espresso owners who backflush regularly and want a cleaner that doesn’t leave chemical residue.
• Drip coffee drinkers who’ve noticed a decline in flavor and haven’t deep-cleaned in months.
• Anyone who hates the smell and taste of vinegar in their coffee gear.

Skip it if you’re only dealing with hard water scale (you need a descaler instead) or if you never clean your machine anyway — this won’t fix neglect overnight.

FAQ

How often should I use Cleancaf? Urnex recommends monthly cleaning for regularly used machines. If you brew multiple times daily, consider every two to three weeks.

Is it safe for all machines? Yes — it’s safe for drip brewers, espresso machines, French presses, pour-over cones, and even commercial equipment. It won’t harm plastic, rubber, or metal components.

Does it descale? No. It removes coffee oils and residue only. For mineral scale from hard water, pair it with a descaling product.

The Verdict

Buy it if you want your coffee to taste as good as it did the day you bought your machine. It’s the most effective oil-removing cleaner I’ve tested, and the food-safe formula means you’re not trading flavor for cleanliness.

Skip it if you’re on a tight budget — the per-use cost is higher than vinegar — or if you’re dealing with hard water scale, where you’ll need a separate descaling product.

Rating: 4.6/5 — not perfect (the small box and lack of descaling capability hold it back), but for its specific job, nothing else at this price does it better.
