Coffee is not just a morning ritual, but a complex chemical extraction process, the result of which depends on the quality of the water. Owners of automatic and carrot coffee machines often face the same problem: a gradual decrease in the quality of the drink and the appearance of extraneous noise when the device is working. The reason for this is scaleIt is formed from the hardness salts contained in tap water. Ignoring this problem can result in costly repairs or a complete replacement of the heating element.
Modern scale-up It is not just an “acid solution”, but a complex chemical composition designed to safely remove sediments without damaging seals and metal parts. Many users mistakenly believe that citric acid or vinegar can be used, but such experiments often end up with the failure of sensitive electronics or pumps. The correct approach to maintenance requires an understanding of the chemistry of processes and compliance with the manufacturer's regulations.
In this article, we will discuss in detail why scale arises, how to choose the right one. decalcinator For your model and step by step describe the cleaning process. You will learn how funds differ for different brands and why regular maintenance saves money in the long run. The safety of your device depends on a competent approach to the choice of cleaning products.
Why is scale formed and how it is dangerous for a coffee machine
The problem is based on a chemical reaction that occurs when water is heated. Tap water contains dissolved salts of calcium and magnesium, which determine its hardness. When the water temperature rises above 60 degrees, these salts precipitate, forming solid deposits of calcium carbonate. This process is accelerated with each brewing cycle, gradually covering the inner walls of the tubes, boiler and thermoblock.
The main danger is not only in the mechanical narrowing of the ducts, but also in the deterioration of thermal conductivity. Scale acts as a thermal insulator, forcing the heating element to work with increased load. TAEN (a tubular electric heater) is forced to heat up to higher temperatures to transfer energy to water through the layer of stone, which leads to its overheating and eventual burnout.
In addition, detached particles of scale can get into the custard block, disrupting the mechanism of sealing the tablet. This causes water to pass through the coffee too quickly or, conversely, the pressure in the system drops. In automatic machines, sensors can consider this a breakdown and block the device from working.
⚠️ Attention: Using tap water without filtration in regions with high water hardness reduces the life of the coffee machine by 3-4 times. Even if the water tastes soft, hardness salts can be present in significant amounts.
Regular use decalcinate This allows you to dissolve these deposits before they become critical. The chemical composition of the means is selected so as to react with carbonates, turning them into soluble compounds that are easily washed out of the system.
Types of means for descaling: comparison of compositions
The market offers many solutions for cleaning coffee appliances, but not all of them are equally effective and safe. The main difference lies in the active substance. Professional scale-up Most often based on sulfamine, lactic or phosphoric acids. These components have sufficient aggressiveness to dissolve the stone, but are safe for food contact after washing.
There are organic acid-based remedies that are milder and take longer to react. They are often used in systems with aluminum boilers that are sensitive to aggressive environments. Mineral acids, on the other hand, act quickly and effectively, but require careful adherence to dosage and exposure time.
- 🧪 Sulfamic acid: The most common component, effective against persistent deposits, has no pungent odor, is safe for most metals.
- 🥛 Lactic acid: It is a soft-action, ideal for delicate systems and aluminum heaters, often used in premium products.
- 🧴 Integrated formulations: contain corrosion inhibitors and surfactants, which not only remove scale, but also create a protective film on the walls, preventing the re-formation of deposits.
It is important to distinguish between means for decalcination and means for cleaning the brewing block from coffee oils. These are different chemical processes: the first removes minerals, the second removes fats and organics. Using scale to wash the brewing mechanism will not give results, since the acid does not dissolve coffee oils.
⚠️ Warning: Never use acetic or citric acid powdered for automatic coffee machines. The crystals may not dissolve completely and damage the pump, and acetic acid destroys rubber seals and has a persistent odor that is difficult to wash.
Top 5 popular means for decalcination: a review of brands
The choice of a particular product often depends on the brand of your coffee machine, however, many versatile products show excellent results. The market leaders are manufacturers specializing in chemistry for coffee industries. Below is an analysis of popular options that have proven themselves in practice.
Special attention should be paid to specialized decalcination DeLonghi, Saeco and Bosch. These liquids are designed taking into account the design features of these brands. For example, the means for Jura often have a tablet form, which simplifies the dosage, while liquid concentrates Durgol It is considered a benchmark of efficiency for professional equipment.
| Brand-funded | Basis | Compatibility | Features |
|---|---|---|---|
| Durgol Universal | Sulfamic acid | Universal. | High speed of action, suitable for any type of scale |
| DeLonghi EcoDecalk | Lactic acid | DeLonghi, Kenwood | Biodegradable, safe for aluminum boilers |
| Saeco Decalcifier | Sulfamic acid | Saeco, Philips | Optimal for systems with ceramic millstones |
| Jura Descaling Tablets | Integrated | Jura | Tablet form, eliminates dosage errors |
| Bosch Tassimo Descaler | Citric acid (special) | Bosch, Tassimo | Especially for capsule systems with thin tubes |
When choosing, the volume of packaging should be considered. For home use, where cleaning is carried out every 2-3 months, it is more profitable to take small bottles or sachets. For offices and coffee shops, where decalcification It is carried out weekly, there are canisters of 1-5 liters, which significantly reduces the cost of one procedure.
Can different tools be mixed?
Mixing different chemical compounds is strictly prohibited. The reaction between different acids or additives can lead to the release of toxic gases, the formation of insoluble sediment or damage to the inner coatings of the coffee machine. Use only one remedy per cycle.
Step-by-step instructions: how to properly decalcinate
The cleaning process may vary depending on the device model, but the overall algorithm of actions remains the same for most automatic and carob coffee machines. Before starting the procedure, be sure to read the instructions for your particular device, as the sequence of button presses may vary.
The first step is always to prepare the solution. Liquid for coffee machine from scale It is usually a concentrate, so it must be diluted with water in the proportion indicated on the package (most often 1: 5 or 1: 10). Use only cold water. Pour the resulting solution into a water tank.
☑️ Checklist before cleaning start
Run decalcination mode through the machine menu or by a combination of buttons. The machine will start to pass the solution through the system. In some models, the process is intermittent: the machine pauses so that the chemical composition has time to dissolve the deposits. Do not turn your device off the network during this process, even if it appears to be frozen.
- Pour the entire solution through a group or hot water supply nozzle.
- Wash the water tank with running water.
- Pour clean water and run the rinse mode at least 2-3 times to remove acid residues.
- Pour the first serving of prepared coffee, as it may contain residues of cleaning agent.
⚠️ Warning: If you feel a sour taste in your coffee or smell of chemistry after washing, repeat the clean water wash cycle. Acid residues can change the pH of a drink and make it unfit for drinking.
Frequent mistakes in cleaning the coffee machine
Even experienced users sometimes make mistakes that negate the entire effect of the procedure or, worse, harm the technique. The most common mistake is to ignore regularity. Many wait until the machine itself requires cleaning or until it starts to work worse. By this point, the scale layer may already be too thick for chemical cleaning.
Another mistake is using hot water to prepare the solution. Many decalcination When in contact with hot water, they begin to react too violently, releasing foam or gas, which can lead to a solution overflow into the car body and the electronics closing. Always use room temperature water.
Users often forget to clean the removable parts. While you're running fluid through the system, cook-blockThe cappuccinator and the pallet remain dirty. Droplets of the solution that have fallen on the rubber seals of the brewing unit without subsequent washing can cause them to dry out and crack.
After completing the decalcination cycle, wipe all available rubber seals and cappuccinator tubes with a wet cloth. This will remove the remnants of the aggressive environment and prolong the life of rubber parts.
Do not try to speed up the process by increasing the concentration of the product. Double dose of acid will not clean the machine twice as fast, but it is guaranteed to damage plastic and aluminum parts. Chemistry takes time to react, and it is time, not concentration, that is the key to success.
How often to clean and how to extend the life of the car
Frequency of procedure decalcination It depends on the hardness of the water in your area and the intensity of the coffee machine. Manufacturers usually recommend cleaning every 2-3 months or after making 200-300 cups. However, in regions with very hard water, this interval should be reduced to 1-1.5 months.
Modern coffee machines are equipped with water hardness sensors. After installing a new filter or changing the region in the settings, the machine itself will calculate the necessary resource. Don’t ignore these (tips) on the display. If the machine requires cleaning and you continue to make coffee, it may go into emergency mode.
To extend the life of the device and reduce the frequency of chemical cleanings, it is recommended:
- 💧 Use filtered or bottled water of low mineralization.
- 🔄 Regularly change the built-in softener filters (if provided by the design).
- 🧼 Conduct daily hygienic cleaning of the brewing block from coffee oils.
Proper water preparation is 80% of the success of a coffee machine. Installation of a good filter-jug or reverse osmosis system will reduce the formation of scale at times.
Remember that prevention is always cheaper than repair. The cost of packaging cleaning products is incommensurable with the cost of replacing the heating element or pump. Regular maintenance will keep the taste of your favorite espresso unchanged for years to come.
FAQ: Frequently Asked Questions
Can I use a tool to remove scale in a teapot for a coffee machine?
No, you can't. Dummies often contain more aggressive components or fragrances not intended for high-pressure food systems. In addition, they may not be pH-balanced for aluminum coffee machine boilers. Use only specialized scale-up.
What if the machine does not see the tool and does not start cleaning mode?
In some models, you need to activate the test mode or reset the cup counter. Try turning off the machine, clamp down a combination of buttons (usually steam and coffee) and turn on. If it doesn't work, consult manual. Sometimes it helps to simply add the product to the tank and start a manual washing program through a hot water supply.
Is the liquid to remove scale dangerous for health?
In concentrated form - yes, it is an acidic solution that can cause burns of mucous membranes. However, after the correct washing cycle (2-3 tanks of clean water) in the system there are no harmful substances. Dissolved calcium salts and residues of safe acid (at permitted doses) are not a threat.
Can I clean the coffee machine if there is some old solution left in the tank?
Absolutely not. Before each procedure, the tank must be completely clean. Mixing an old, possibly oxidized solution with a new concentrate can alter the chemical properties of the liquid and reduce its effectiveness or lead to unpredictable reactions.
Why did coffee taste worse after cleaning?
It's a temporary phenomenon. Microscale particles or residues of the product could remain in the system. Cook 3-5 cups "waste" (just spilling water) or drink the first portions. If the taste is not every other day, repeat the cycle of washing with clean water.
