Key takeaways
- After each use, flush the group head with water and wipe the steam wand immediately so milk never dries on it.
- Backflush machines with a blank filter and a cleaning tablet, like Breville BEC250 espresso cleaning tablets, weekly to clear oils from the group.
- Wash the portafilter, basket, and drip tray with warm soapy water regularly and soak them if oils build up.
- Wipe the exterior and empty the drip tray daily so grime and stale water never accumulate.
What's inside
A neglected espresso machine slowly sabotages every cup. Coffee oils go rancid in the group head, and mineral scale from hard water coats the boiler and narrows the internal pipes, dropping temperature, weakening pressure, and lending your shots a sour, metallic edge. The good news: a simple two-part routine, regular cleaning plus periodic descaling, keeps a machine pulling great espresso for years.
This guide walks through exactly how to clean and descale your espresso machine effectively, how often to do each, and which products make it painless. It covers Breville, Nespresso, De’Longhi, Ninja, and other popular machines, using cleaning tablets, descaling solutions, and universal descalers so you can match the right product to your setup.

Cleaning vs Descaling: Know the Difference
These are two separate jobs and both matter. Cleaning removes coffee oils and grounds from the group head, portafilter, and drip tray, and you do it frequently. Descaling dissolves the mineral scale, mostly calcium, that builds up inside the boiler and water lines from hard water, and you do it periodically. Skip cleaning and your shots taste bitter and stale; skip descaling and scale eventually clogs the machine and kills its heating efficiency.
How to Clean Your Machine Regularly
- After each use, flush the group head with water and wipe the steam wand immediately so milk never dries on it.
- Backflush machines with a blank filter and a cleaning tablet, like Breville BEC250 espresso cleaning tablets, weekly to clear oils from the group.

How to Descale Step by Step
Descaling is straightforward with the right solution. Choose a descaler suited to your machine, a Breville-specific descaler for Breville units, or a universal option like IMPRESA or Durgol Swiss Espresso for most brands, then follow this sequence: empty and rinse the water tank, mix the descaling solution with water per the label, and run it through the machine in cycles as directed. Flush thoroughly afterward with two or three tanks of fresh water so no descaler taste lingers in your next shot.
For pod and drip machines, tablet descalers that work across Nespresso, Keurig, Ninja, De’Longhi, and Miele make the job simple, just drop, run, and rinse. Breville owners can use a dedicated descaling kit for a full-cycle clean.
How Often Should You Descale?
Frequency depends on your water and usage. With hard water, descale every four to six weeks; with soft or filtered water, every two to three months is usually enough. Many machines flash a descale light based on shot count, treat that as your reminder. Using filtered water in the tank slows scale buildup dramatically and stretches the interval between descaling sessions.
Tips
- Use filtered or bottled water to slow scale formation and improve taste at the same time.
- Never skip the post-descale rinse, since leftover solution ruins the flavor of your next shots.
- Match the descaler to your machine; brand-specific formulas like the Breville descaler are made for that unit’s materials.
- Keep a small supply of cleaning tablets and descaler on hand so you never postpone maintenance.
Frequently Asked Questions
Can I use vinegar to descale my espresso machine?
You can in a pinch, but it is not ideal. Vinegar is harsh on internal seals, leaves a stubborn smell, and needs extensive rinsing. Purpose-made descalers like Durgol or IMPRESA are gentler on components and formulated to dissolve scale cleanly, so they are the safer long-term choice.
How do I know when my machine needs descaling?
Watch for slower flow, lower pressure, cooler shots, longer heat-up times, or a sour taste, all signs of scale buildup. Many machines also have a descale indicator light tied to usage. When you notice these symptoms, it is time to run a descaling cycle.
Is descaling the same for pod machines and espresso machines?
The principle is identical, dissolve and flush out mineral scale, but the method differs. Pod machines like Nespresso and Keurig use tablet or solution descalers run through their cycle, while traditional espresso machines may need backflushing and brand-specific solutions. Always follow your machine’s instructions.
Will descaling remove old coffee oils too?
No, descaling targets mineral scale, not coffee residue. Removing oils is the cleaning job, done with backflushing and cleaning tablets like the Breville BEC250. You need both routines: regular cleaning for oils and periodic descaling for scale.
Conclusion
Keeping your espresso machine in top form comes down to two habits: clean often to clear coffee oils, and descale periodically to dissolve mineral scale. Match the right products to your machine, whether a Breville-specific kit or a universal descaler, use filtered water to slow buildup, and always rinse thoroughly afterward. Stay consistent and your machine will reward you with hot, full-pressure, great-tasting espresso for many years.
