If you’re making espresso every day, whether at home in the office or in a café, it doesn’t take long before your machine starts showing signs of wear. A little dried milk on the steam wand, a few stray coffee grounds around the group head, and suddenly your shot quality begins to dip. The truth is, espresso machines aren’t maintenance free and as such requires a solid daily cleaning routine.
Without proper care the flavour starts to suffer, machine parts wear faster and you could be heading for costly repairs or service interruptions. Cleaning your machine each day helps you preserve not only the equipment itself but also the integrity of every cup that comes through it.
Start With the Basics
Once the last cup of the day is pulled, it’s time to clean things down.
First up is the basics. Take a few moments to empty the drip tray and knock out the puck box if you’re using one. Rinse both parts under hot water to get rid of any built up coffee oils or grounds. Wipe everything dry and put it back. This only takes a few minutes but goes a long way to keeping bacteria and odours at bay.
Then, look at the exterior. Even though it doesn’t directly affect the taste of your coffee, keeping the outside of the machine clean helps prevent build up and keeps things hygienic. Use a clean, damp cloth to wipe around the buttons, body and especially under the portafilter area where coffee splashes tend to settle. Don’t forget the drip tray area and even a quick wipe down can make a big difference.
Give Attention to the Portafilters and Baskets
This part of the machine does most of the heavy lifting during each brew. After a long day of use, the portafilter and basket can get pretty grimy, especially around the edges and the tiny holes in the filter basket. Give these a rinse under hot water, but once a day it’s worth soaking them in a cleaning solution. Use a coffee safe detergent, and let the parts soak for 10 to 15 minutes to dissolve old oils and grinds. Rinse everything thoroughly afterward to avoid any leftover soap flavour making its way into tomorrow’s espresso.
Don’t Skip the Group Head and Backflush Routine
The group head is where your coffee meets hot water, and it’s constantly exposed to fine grounds and oils. Use a small brush to scrub around the group seal and screen to loosen anything stuck in there.
Then comes the backflush. This step is vital for commercial machines and useful even for serious home setups. Insert a blind filter (a filter basket with no holes), add a little espresso machine cleaner and run your machine in short bursts. You’ll see the water turn brown, that’s all the gunk being dislodged from behind the scenes. Repeat until the water runs clear, then flush a few times with just water to rinse it out properly.
The Steam Wand Deserves Extra Care
Milk residue is a magnet for bacteria and a major culprit for unpleasant smells. After each milk based drink, always purge the steam wand and wipe it down. But once a day, take things further. Soak the wand tip in warm water mixed with cleaning detergent. If your wand unscrews, take it apart to scrub inside any crevices. Even a quick soak can remove hardened milk residue that a cloth can’t reach. Keeping your steam wand clean means smoother steaming and better-tasting milk for lattes and cappuccinos.
Final Flush and Ready for Tomorrow
To wrap things up, it’s important to run some clean hot water through the group head and steam wand. This flushes out any detergent or leftover coffee residue. You’ll know it’s clean when the water runs clear and the machine smells fresh. Give the entire machine a final wipe down and check that everything’s dry. Now your machine is not only clean but also primed for another day of brewing.
