You can buy excellent coffee beans, invest in an expensive espresso machine and learn the perfect brewing technique. But there is one important thing that many coffee lovers and even professional coffee businesses often overlook: keeping the coffee machine properly clean.
Have you ever noticed that your coffee does not taste as good as it used to? Perhaps the espresso has become more bitter, the aroma is weaker, the crema looks different, or the colour of the finished drink is no longer as consistent as before.
Many people immediately blame the coffee beans, the grinder or the machine settings.
However, sometimes the problem is much simpler.
Your coffee machine may need a proper cleaning.
Every time coffee is prepared, small amounts of coffee oils and residues remain inside the equipment. Over time, these deposits accumulate in parts of the brewing system that are not visible during everyday use.
This is exactly where professional coffee machine cleaning tablets become important.In this article, we explain what cleaning tablets do, what they remove, how often they should be used and why regular cleaning is essential for maintaining coffee quality and protecting your equipment.
Coffee is a natural product containing oils and other organic compounds. During extraction, some of these substances remain on the internal surfaces of the coffee machine.
With every cup, small quantities of coffee residue can accumulate in:
The exact areas cleaned depend on the machine design and the cleaning programme.At first, the deposits may be almost impossible to notice. The machine continues to prepare coffee, and everything seems normal.
But gradually, coffee oils and old coffee residues build up. These residues can affect the taste and aroma of freshly prepared coffee and interfere with the proper operation of the brewing system.
According to JURA, its cleaning programme removes coffee residues, oils and fats from the brewing unit. The manufacturer also warns that postponing the cleaning programme allows these deposits to accumulate and noticeably reduces coffee quality.
A clean coffee machine is not simply a matter of appearance. It is an important part of preparing good coffee consistently.
Coffee machine cleaning tablets are specially formulated cleaning products designed to remove accumulated coffee oils, fats and residues from designated parts of coffee equipment.
They are particularly important for automatic coffee machines and professional espresso machines that have dedicated cleaning programmes or procedures.
Unlike ordinary rinsing with water, specialised cleaning products are designed to tackle coffee deposits that cannot always be removed through a simple water rinse.
When used in accordance with the machine manufacturer's instructions, cleaning tablets help maintain the cleanliness of the brewing system and the internal surfaces through which coffee passes.
For example, De'Longhi explains that its coffee cleaning tablets remove residues left behind during coffee preparation and help maintain a clean coffee taste. Philips recommends coffee oil remover tablets to remove accumulated oils from the brew group filter on applicable machines.
Coffee oils
Coffee beans naturally contain oils. During grinding and extraction, these oils come into contact with internal machine components and gradually accumulate.
Old coffee oils can develop stale or rancid aromas, which may affect the taste of freshly prepared coffee.
Coffee residues
Small coffee particles and deposits may remain in brewing components, filters, group heads and internal coffee pathways.
Over time, these residues can accumulate and interfere with proper water flow and extraction.
Fat and organic deposits
Coffee-related fats and other organic residues can form a layer on internal surfaces. Specialised cleaning tablets help break down and remove these deposits during the machine's designated cleaning cycle.
There is an important distinction between cleaning and descaling.
Coffee cleaning tablets are not descaling tablets.
They are designed primarily to remove coffee oils and residues, not mineral deposits caused by hard water.
Limescale accumulates inside water circuits, boilers and other components where water is heated or circulated. It requires a suitable descaling product and the appropriate maintenance procedure.
For this reason, proper coffee machine maintenance normally requires different products:
Each product has a specific purpose. Using the correct cleaning solution for each part of the equipment is essential.
This is one of the most important reasons to maintain a coffee machine regularly.
A machine can continue to prepare coffee even when its internal components have accumulated considerable amounts of old coffee residues.
The problem is that the quality of the drink may gradually deteriorate.
Fresh coffee should have its characteristic aroma, balanced flavour and pleasant aftertaste.
When old coffee oils and residues accumulate, they may affect the flavour of subsequent preparations.
Coffee can develop:
De'Longhi specifically notes that accumulated oils and grime can make coffee taste bitter. JURA also warns that delayed cleaning noticeably reduces coffee quality.
Coffee quality is not only about taste. Appearance matters too.
A properly maintained brewing system helps provide more consistent extraction.
When parts of the brewing system become partially blocked by coffee deposits, water may not pass through the coffee evenly.
This can affect the quality and consistency of the espresso crema. It may become weaker, less uniform or less attractive.
The appearance of the coffee in the cup can also become less consistent.
Cafetto describes how a partially blocked espresso machine shower screen can lead to uneven extraction, poor crema and bitter coffee.
It is worth remembering that crema and coffee colour also depend on bean variety, roast level, freshness, grind setting and extraction parameters. Cleaning is one important factor, not the only one.
Accumulated coffee deposits can interfere with the operation of components responsible for distributing water and extracting coffee.
A dirty or partially blocked shower screen, for example, can lead to uneven extraction. More severe blockages may require professional servicing.
In some machines, coffee residue can also affect the operation and sealing of brewing components.
This is why regular cleaning is not just about making coffee taste better. It also helps keep the equipment working correctly.
Yes. Insufficient maintenance can contribute to operational problems and increase the risk of expensive repairs.
Coffee machine components operate under specific conditions involving heat, water pressure and repeated mechanical movement.
When deposits accumulate, they can interfere with the normal operation of some components.
Possible problems include:
It is important to understand that cleaning tablets alone cannot prevent every possible machine failure.
For example, limescale requires descaling, while worn mechanical parts require appropriate technical servicing.
However, regular cleaning is an essential preventive maintenance measure.
Bosch warns that dirt and limescale accumulation can damage internal components and lead to costly repairs. Professional cleaning product manufacturer Cafetto also explains that heavy blockage of an espresso machine shower screen may require a service call.
A cleaning tablet costs far less than an avoidable repair or a coffee machine that cannot be used during a busy working day.
This is one of the most frequently asked questions.
There is no single cleaning interval that applies to every coffee machine.
The correct frequency depends on:
The most important rule is simple:
Always follow the maintenance instructions of your coffee machine manufacturer and the instructions supplied with the cleaning product.
Many modern automatic coffee machines have integrated cleaning programmes.
The machine may display a cleaning notification after a certain number of coffee preparations or according to its internal maintenance counter.
For example:
Philips recommends rinsing the brew group weekly on applicable models and using coffee oil remover tablets monthly to clean accumulated oils from the brew group filter.
JURA provides an automatic cleaning notification. For one particular model, the C9, its manual specifies a cleaning prompt after 180 preparations or 80 switch-on rinses.
These are examples for specific machines, not universal intervals.
Commercial coffee machines often prepare significantly more drinks than domestic machines.
This means that coffee residues and oils can accumulate more quickly.
Professional coffee equipment therefore requires a more structured cleaning routine.
Depending on the machine and the manufacturer's instructions, the maintenance routine may include:
Professional cleaning manufacturer Cafetto recommends daily use of an espresso machine cleaner on commercial machines as part of maintaining extraction quality and equipment life.
The exact procedure and product must still match the coffee machine manufacturer's instructions.
For a coffee shop, restaurant or hotel, cleaning should be part of the normal working routine, not something that happens only when the coffee machine starts showing problems.
A clean machine helps maintain a consistent coffee experience throughout the day.
Many coffee machine owners believe that the automatic rinsing programme is sufficient to keep their equipment clean.
This is a common misunderstanding.
Automatic rinsing is useful because it removes some loose coffee particles and flushes water through designated parts of the machine.
However, water alone may not remove all accumulated coffee oils and fats.
Specialised cleaning products are designed to deal with these deposits.
JURA explains that its cleaning programme uses a dedicated tablet to remove coffee residues, oils and fats from the brewing unit. Its cleaning process is different from ordinary rinsing.
The distinction is straightforward:
Water rinsing removes some loose residues.Specialised cleaning removes deposits that require a cleaning formulation.
Both procedures are important, but they are not interchangeable.
This is an interesting question.
People spend considerable time choosing coffee beans, comparing coffee machines and learning how to prepare espresso.But regular equipment maintenance is often overlooked.
There are several reasons.
When purchasing a modern automatic coffee machine, customers usually focus on its design, functions, drink selection and convenience.
Cleaning is often presented as a secondary feature.The buyer may not fully understand that the brewing system also requires regular attention.
Coffee residues accumulate in internal components that are not visible from the outside.
The machine may look perfectly clean, even when its brewing system requires maintenance.
Unlike a dirty cup or countertop, internal coffee deposits are not immediately obvious.
Many machines rinse automatically when they are switched on or off.
This is convenient, but users may assume that the machine cleans itself completely.
In reality, automatic rinsing and specialised cleaning programmes perform different tasks.
Many users do not think about maintenance until they notice bitter coffee, unpleasant aromas, unusual operation or a maintenance warning.
By that stage, coffee residues may have been accumulating for quite some time.
Some people see cleaning tablets as an additional cost.
But the correct way to look at it is as part of the normal cost of operating a coffee machine.
Regular preventive maintenance is generally more sensible than waiting until equipment problems appear.
For professional coffee businesses, a coffee machine is not simply a kitchen appliance.It is an important part of daily revenue and customer satisfaction.
A café may prepare hundreds of drinks every day. Restaurants and hotels also depend on consistent coffee quality throughout their operating hours.Imagine a customer ordering the same espresso twice in one week.
The coffee beans are identical. The machine settings have not changed. Yet the second coffee tastes bitter, has a weaker aroma and looks different.
One possible reason is the condition of the equipment.
Maintain consistent coffee quality
Regular cleaning helps minimise the influence of accumulated coffee residues on flavour and extraction.
Support professional hygiene routines
Cleaning is a necessary part of the regular maintenance of equipment used to prepare drinks for customers.
Reduce avoidable interruptions
Preventive maintenance helps identify and address contamination and deposits before they develop into more serious operational problems.
Protect equipment investments
Commercial coffee machines represent a significant investment. Proper maintenance helps support their long-term operation.
Maintain customer confidence
Customers expect consistent drinks and professional service every time they visit.
A clean coffee machine is an important part of that experience.
Not all coffee cleaning tablets are necessarily suitable for every coffee machine.
Before purchasing, pay attention to several important factors.
Cleaning tablets are available in different weights and sizes.
The correct tablet format depends on the cleaning programme and equipment requirements.
Always check the required dosage in the machine manual and product instructions.
Some machines require specific tablet dimensions or formulations.
Using an unsuitable cleaning product may damage equipment or leave residues inside the machine.
For example, JURA explicitly warns that using an incorrect cleaning agent may damage its machine or leave traces in the water.
Check whether the product is designed for:
Do not assume that a tablet designed for one type of cleaning can be used for every machine.
For professional use, it is important to have access to the relevant technical information and Safety Data Sheet (SDS).This is particularly important for cafés, restaurants, hotels and companies responsible for cleaning and maintaining commercial equipment.
Use the quantity specified by the manufacturer.
Run the designated cleaning programme and complete all required rinsing stages.
Do not interrupt the cleaning cycle or use the machine to prepare drinks until the programme has been completed as instructed.
Never mix different cleaning products unless the manufacturers explicitly specify that this is permitted.
Cleaning tablets are essential, but they are only one part of proper coffee equipment maintenance.
Different components require different products and procedures.
A professional coffee care routine should consider:
Coffee machine cleaning tablets
For removing coffee oils, fats and residues from the brewing system.
Coffee machine descalers
For removing limescale and mineral deposits from the water system.
Milk system cleaners
For removing milk fats, proteins and other milk-related deposits from milk circuits and frothing systems.
Coffee grinder cleaners
For removing accumulated coffee oils and old coffee residues from grinder components.
Regular manual cleaning
For cleaning portafilters, baskets, shower screens, drip trays, water tanks and external surfaces according to the machine manufacturer's instructions.
No single cleaning product replaces all the others.
A complete maintenance routine is what helps keep coffee equipment in proper working condition.
A good coffee machine is an investment.
Whether you use a compact automatic coffee machine at home or operate professional espresso equipment in a busy café, regular cleaning should be part of your routine.
Do not wait until coffee starts tasting unpleasant or the machine displays a maintenance warning.
Pay attention to the manufacturer's recommendations, use appropriate cleaning products and follow the recommended cleaning procedures.
Remember:
