How Cafetto Espresso Machine Cleaning Powder Makes Coffee Taste Better
If your coffee suddenly tastes bitter, flat, muddy or just tastes 'off', there’s a good chance it’s not your beans and it’s your machine.
Coffee oils, fines and residue build up quickly inside your espresso machine. Over time, this buildup starts to affect flavour, mute sweetness, and introduce harsh or stale notes into your cup. The fix is simple: a proper cleaning routine using a dedicated product like Cafetto Espresso Machine Cleaning Powder.
In this article, we break down how Cafetto works, why it matters for home and cafe espresso machines, and how a clean machine can dramatically improve the taste of your coffee.
Why Cleaning Your Espresso Machine Matters
Every time you pull a shot, oils from coffee extract and stick to internal parts of your machine such as the group head, shower screen, valves and internal water pathways.
These oils don’t just sit there, they oxidise. When that happens, they turn rancid and begin to affect every shot you pull afterwards.
Even if you’re using high quality coffee beans, dialing in properly and following a good recipe, a dirty machine will dull acidity, reduce sweetness, add bitterness and create inconsistent shots throughout your workflow.
What is Cafetto Espresso Machine Cleaning Powder?
Cafetto Espresso Machine Cleaning Powder is a purpose-built cleaner designed to remove coffee oils, residue, and buildup from your espresso machine.
Unlike generic cleaners, Cafetto is formulated specifically for coffee equipment, meaning it breaks down stubborn coffee oils, rinses clean without leaving residue and is safe to use on espresso machine components.
It’s widely used in cafes and by home baristas who want consistent results and high-quality tasty coffee.
How Cafetto Improves Coffee Taste
Using Cafetto cleaning powder regularly helps restore your machine back to neutral which is exactly what you want.
1. Removes Rancid Coffee Oils
Old coffee oils are one of the biggest flavour killers. They introduce bitterness and mask the natural characteristics of your coffee.
Cleaning with Cafetto removes this buildup, allowing your coffee to taste cleaner, brighter and more defined.
2. Improves Shot Consistency
A dirty group head can affect water flow and pressure, leading to uneven extraction. After cleaning your espresso machine with Cafetto, you’ll often notice more consistent flows, better shot repeatability and overall your coffee will be easier to dial in.
3. Restores Clarity and Sweetness
When your machine is clean, your coffee can actually express itself properly. You’ll start tasting clearer flavour notes, improved sweetness and better balance in your cup.
This is especially noticeable with lighter roasted coffees and higher-quality coffee beans.
How to Use Cafetto Espresso Machine Cleaning Powder
A standard cleaning routine is quick and easy but how often you clean your machine should be based off usage. A cafe may need to clean their machine once a night before closing while a home coffee machine can benefit from a deep clean every week - month based off usage.
Backflushing (for machines with a 3-way valve)
This process removes internal buildup from the group head and valves. Please make sure to read your coffee machines backflushing and maintenance instructions before doing this. Each machine is different and will have light variations in how it backflushes.
- Insert a blind filter into your portafilter
- Add a small amount of Cafetto Espresso Machine Cleaning Powder
- Lock into the group head
- Run the pump for ~10 seconds, then stop
- Repeat several times
- Remove, rinse, and flush thoroughly with clean water
- Pull 2-3 shots with old coffee and dispose of.
Don’t Forget Your Grinder
Cleaning your espresso machine is only part of the equation. Your grinder also builds up with coffee oils, fines (tiny particles of coffee) and static-heavy residue. Using a Coffee grinder brush and a reusable air duster is one of the simplest ways to maintain your setup.
At Basic Barista, we recommend brushing out your grinder regularly to keep grind size consistent, reduce stale coffee contaminating your freshly brewed coffee and to improve overall cup quality in your coffee!
What About Descaling?
While Cafetto cleaning powder removes coffee oils, it does not remove mineral buildup. That’s where a liquid descaler comes in.
Descaling targets limescale and mineral deposits from your water, and if you're using tap water a regular descaling procedure is absolutely essential!
How Often Should You Clean Your Machine?
This depends on usage, but as a general guide:
- Daily use (home): clean every 1-2 weeks
- Heavy use: clean weekly
- Cafe use: daily cleaning is standard
Grinders should be brushed out every few days (or more if used heavily).
If you’re chasing better coffee at home, one of the easiest upgrades isn’t new gear, it’s maintenance.
Using Cafetto Espresso Machine Cleaning Powder keeps your machine free from old oils and residue, allowing your coffee to taste the way it’s meant to. Pair this with a Coffee grinder brush and occasional use of a Cafetto descaler, and you’ll have a setup that delivers consistently clean, balanced and enjoyable coffee.
At Basic Barista, we see it all the time, people upgrade their beans, grinders and recipes, but overlook cleaning. Once they start using Cafetto regularly, the difference is immediate.
