Should you clean your portafilter machine yourself or have it cleaned by a professional?
Owning a portafilter machine is, first and foremost, a pleasure. But this pleasure remains consistent only if the portafilter machine is properly maintained, and that includes regular deep cleaning.
This raises the question of just how complicated a deep cleaning like this actually is, and whether you can do it yourself or should have it done by a professional.
Deep Cleaning for Portafilter Machines—Here's How!
Is a deep clean of a portafilter machine actually the same as a regular clean? No, because regular cleaning begins with the daily routine after each cup of coffee. A deep clean, on the other hand, is a type of thorough cleaning that is performed at regular intervals.
Here's what sets daily cleaning apart from deep cleaning:
| Daily Cleaning | Deep Cleaning | |
|---|---|---|
| Objective | Removal of coffee residue and fresh oils | Removal of stubborn and baked-on coffee grease and limescale |
| Duration | 1–2 minutes | About 30 minutes |
| Interval | After each use | About once a month—varies depending on frequency of use |
Must-haves: The Right Supplies for Your Deep Clean
If you want to give your portafilter machine a thorough cleaning yourself at home, you'll need the following items:
- Microfiber Cleaning Cloths
- Descalers & Grease Removers
- Cleaning brush
- Blind sieve
- Brewing Head Cleaner
- Brewing Unit Brush
- Screwdriver

Step-by-Step Guide to Deep Cleaning Your Portafilter Machine
1. Turn off the machine and let it cool down
Turn off the espresso machine and let it cool down sufficiently. Then remove Portafilter, the filters, and other accessories.
2. Clean the housing and work area
Thoroughly wipe down the housing, the drip tray, and the steam wand with a microfiber cleaning cloth. This will remove coffee residue, water spots, and fingerprints.
3. Brush out the brew group
Use the brew group brush to remove loose coffee grounds from around the brew group. Then use the cleaning brush to remove coffee grounds from hard-to-reach corners and gaskets.
4. Clean the shower strainer
Carefully unscrew the shower strainer with a screwdriver. Clean the strainer thoroughly with a showerhead cleaner and remove all grease and coffee residue. Then rinse it carefully and reinstall it.
5. Backflush the brew group
Place the blind filter into the Portafilter and add the recommended amount of brew head cleaner. Then:
- Portafilter clamp.
- Let the pump run for about 10 seconds.
- Stop the pump and let the cleaner sit for a few seconds.
- Repeat the step 5 to 10 times.
- Next, rinse out the blind filter and perform several backflushes using only clean water.
This removes coffee oils and deposits from the internal lines of the brew group.
6. Degrease the Portafilter , and sieves
Soak the " Portafilter " and "Siebe" in a solution of warm water and degreaser according to the manufacturer's instructions. Then rinse thoroughly and dry.
7. Descale the machine
Use a suitable descaling agent in accordance with your machine's instruction manual. After descaling, rinse the system several times with fresh water to remove all residue.
8. Final Cleaning
Also, be sure to clean and dry your utensils after each use. Dry them with a clean microfiber cloth. That’s why it’s a good idea to always have several microfiber cloths at home so you can replace the dirty ones.
Once all the components of the portafilter machine are dry, they can be reassembled.
Following this routine will keep your portafilter machine hygienically clean and ensure it consistently delivers espresso with a full-bodied flavor.
Service: Professional Deep Cleaning for Portafilter Machines
So anyone can learn how to give their machine a thorough cleaning. Practice and routine are what make the master. However, if you don’t have the time or inclination to do it yourself, you can also have your portafilter machine cleaned at a professional service center.
Benefits of Professional Deep Cleaning by Experts
Professional deep cleaning offers particular benefits for espresso machines that have been heavily used or have not been maintained for a long time. Specialized service providers thoroughly clean hard-to-reach areas, inspect wear-and-tear parts such as gaskets and filters, and can identify potential defects early on. This often helps prevent drops in performance, changes in flavor, or costly repairs.
Especially for coffee lovers who use their portafilter machine every day, a professional deep cleaning at regular intervals can be a useful addition to their own maintenance routine. This helps keep the espresso machine in good working order and ensures consistent espresso quality over the long term.
Are maintenance and professional deep cleaning the same thing?
No, professional cleaning is not automatically the same as maintenance. While cleaning removes limescale, coffee oils, and other deposits, maintenance also includes a technical inspection of the machine.
During this process, components such as gaskets, valves, strainers, hoses, and other wear parts are inspected and replaced as needed. Depending on the service provider, functions such as pressure, temperature, or the machine’s leak-tightness may also be checked.
Anyone who has their portafilter machine cleaned outside the home should therefore clarify in advance which services are included. Many specialty shops offer both a basic cleaning service and combined cleaning and maintenance packages.
To ensure long-term value retention and consistently high-quality espresso, it is recommended to supplement regular self-cleaning with occasional professional maintenance.

How do I clean my coffee grinder?
Quick Answer:
Clean your coffee grinder regularly to remove rancid coffee oils and ensure consistent grinding results. Use a cleaning brush after each use, perform a granule cleaning (e.g., with Puly Grind Crystals) once a month, and manually clean the hopper and burrs every 1–2 months. Do not use rice—it can damage the burrs.
Oil can go rancid, including the oil that seeps out of the coffee beans during grinding and sticks to the various parts of the coffee grinder. In addition, this undrinkable oil mixes with the fresh beans and gives the coffee an unpleasant taste. In addition to affecting the taste, residual oils from the coffee beans also impact the grinder’s performance, as they eventually cause the grinding disc to become clogged. This makes it impossible to produce a uniform, fine espresso grind, and as a result, you won’t be able to make a good espresso.
If you clean your coffee grinder regularly, you'll not only be rewarded with great-tasting coffee, but also with a longer lifespan for your grinder.
Instructions for Cleaning Your Coffee Grinder, with Product Recommendations
There are several ways to clean your coffee grinder. Before we explain the different cleaning methods, here is a list of items that are essential for cleaning coffee grinders. It also includes some product recommendations from our experts.
To clean your coffee grinder, you'll need:
- A microfiber cloth
- Puly Grind Crystals for cleaning with granules
- A mild detergent
- A suction device (e.g., a vacuum cleaner)
- A soft cleaning brush
- Warm water
We'll explain how to best clean the hopper and grinder by hand, as well as how to clean the granules:
Cleaning the Hopper and Grinding Mechanism in an Electric Coffee Grinder
Before you begin disassembling the coffee grinder and removing the hopper and grinder, make sure the power cord has been unplugged.
Start by vacuuming the individual components to remove the first layer of dry, loose coffee grounds. This step makes the subsequent wet cleaning much easier and cleaner.
The funnel can be washed by hand with warm soapy water. Any soap residue must also be rinsed off with warm water before drying the funnel with a microfiber cloth.
Clean the grinding mechanisms with a soft cleaning brush. More stubborn residue can be wiped away in specific areas with a microfiber cloth.
The exterior of the coffee grinder can also be cleaned with a damp cloth. If the exterior housing is made of stainless steel, you can restore your coffee grinder’s shine using the ECM polishing cloth.
Cleaning a Coffee Grinder with Granules
The bean container must be completely empty before using the cleaning granules. If there are small bean residues in the container, they must first be ground down until no more come out.
Puly Grind Crystals, for example, is a recommended coffee granule. This product is available Espresso Perfetto online store.
Here's how it works:
Place about 35–40 g of Puly Grind into the empty bean hopper and grind the entire amount of granules to a medium grind. This process releases coffee oils, fat residues, and fine coffee dust. Then empty the drip tray and brush out the grinding chamber with a brush.
Now add a small amount (about 20 g) of coffee beans to the grinder and grind them completely as well. Be sure to discard the resulting coffee grounds.
Things to Avoid When Cleaning with Granules:
- Do not mix with water
- Don't put it in damp mills
- Do not use with grinders that have a built-in brewing unit (grinder only!)
Can I clean my coffee grinder with rice?
Almost everyone has rice at home, so you might be interested in this cleaning method. However, cleaning your coffee grinder with rice grains could damage it.
Why You Should Choose Pet Food Pellets Over Rice:
You may be familiar with the method of placing a wet cell phone in rice. It works the same way for oily residue in a coffee grinder. Rice absorbs not only moisture but also oils, ensuring that the grinding mechanism in the coffee grinder produces a consistent espresso powder again. However, there’s a big BUT when it comes to cleaning with rice.
There are three reasons why cleaning with rice is not recommended:
- Rice is harder than coffee and, due to its coarse grind, can damage plastic parts, cause the grinding mechanisms to wear out faster and more severely, and overload the motors.
- When rice is finely ground, rice starch is released. If this starch comes into contact with moisture, it can clump together and cause the coffee grinder to become clogged from the inside. Rice starch is even harder to remove than coffee grounds and the oil from coffee beans.
- For these reasons, depending on the manufacturer, the coffee grinder's warranty may be voided if foreign materials such as rice are used for cleaning.
Conclusion on the rice method: Cleaning granules like Puly Grind Crystals are better suited for cleaning the coffee grinder!
How often should I clean my coffee grinder?
A coffee grinder doesn't need to be thoroughly cleaned every day—it's perfectly sufficient to remove the coffee grounds from the grinder with a cleaning brush after each use.
With average use, it’s a good idea to clean the coffee grounds about once a month, and you should manually clean the hopper and grinder with a cleaning brush and microfiber cloth every 1–2 months.
Cleaning the grounds is recommended only for particularly oily coffee beans, about every 2–3 weeks.
