- Cleaning rags
- Scrub brushes
- Espresso cleaner or Detergents

How to Clean an Espresso Machine
Now let us get into how to clean an espresso machine proper. For light cleaning, all you have to do is the following:
- Shake the lingering ground coffee from the basket after every espresso shot and flush it out.
- Dab the basket with a clean, dry rag.
- Connect the portafilter to the group head and place it under running water a few seconds.
So let’s see what are the steps to clean espresso machine:
Step 1: Back Washing
Backwash your machine regularly. If you use it daily, once a month will be sufficient.
Insert a blind filter (this is usually a hard filter plate that normally comes with your device). It prevents water from running through the portafilter) into the portafilter. Now run the hot water as you would for an espresso.
- Stick in the blind filter and add up to 1/2 teaspoon (3 g) of your espresso detergent. Latch the portafilter unto the showerhead.
- Initiate brewing for at least 10 to 30 seconds. This process allows the detergent to pass through the machine’s usual cycle while cleaning. Repeat this as much as three times for light cleaning and up to 10 for deep cleaning.
- Detach the portafilter then initiate a brew cycle. You can now rinse the portafilter from the water via the group head.
- Stick in the blind filter. Latch your portafilter into the group head again. At this time, you should have a clean blind filter without the cleaner. Now rerun an espresso cycle without any detergent this time. Do this for like two times.
- You can make a test shot of espresso to backwash the detergent.
- Saturate the filters and the metal part of the portafilter but not the plastic handle. Try this for about 30 minutes in a teaspoon of detergent and (1 L) of hot water.
- Wash out with water and return the filters. Then repeat running an espresso cycle as in step.
- Run it for 5 seconds and then let it sit for ten. The water then empties into the drip tray.
- Next, top up the portafilter with your preferred cleaning agent and run an espresso-making cycle, repeat several times. Do this again with fresh water to ensure that all the detergent washed out. Make sure your reservoir is full before you start. This will remove any coffee oil debris that has gathered up over time.
Step 2: Brushing the Basket
You need to detach the basket away from the portafilter and scrub. Try using the dedicated porta filter brush for this task. Some people just put this in hot water to wear the dirt away. But if you can run the heated water even if it’s gradually, you will get better results.
Step 3: Cleanse the Showerhead
Wield the brush on the showerhead. First, dilute some espresso cleaning detergent. Dip the brush in it and swab. Pay due diligence to this particular task because ground coffee amasses over time.
Step 4: Tidying up the Steam Wand
like a real magic wand, the steam wand is capable of releasing gaseous like steam. Unlike the magic wand in Harry Potter, however, it requires constant cleaning after every use. Sometimes stuff like milk, the cream may fall on it.
To avoid them melting and sticking to the steam wand, you have to clean with a rag. If you can get a non-tipped slim metal to pass through the pipe and clear residues, that would be awesome. Some espresso brushes come with such dandy pinheads.
You should also follow a routine of purging the duct with clean heated water mixed with the cleaning detergent. In this method, remove the tip and soak in the same hot mixture for 3 to 12 hours.
Step 5: Clearing the Draining Hose
The draining hose performs similar functions just like your trash can only more automatically. So it is best to avoid any clog or coffee debris build up in the drip-tray pipes.
Step 6: Cleaning the Dispersion Screen
Can you negotiate a screwdriver, then try cleaning the dispersion screen. Dispersion screens work for the diffusion of water from the group head. It helps to spread the coffee well in the portafilter basket. Cleaning the dispersion screen in few easy steps should be possible for most machines.
- Remove the screen by unscrewing the bolt at the center of the screen. It may be a flathead nut or just a bolt.
- Then soak the screen, either in warm water mixed with espresso detergent before scrubbing or can outrightly start scrubbing. If you have a paleo brush, this would be handy too, as you can also clean with your clothe rags. If you have a machine that has an internal and external dispersion plate, then feel free to clean those too. You aim to make sure this machine disperses water evenly, which is crucial to make a perfect shot of espresso.
- When the screen looks very clean, and now you cannot see coffee debris on it, then reattach it back. You should do this by fastening the screw back in the same way you loosened it.
