Water is life for the coffee machine, but it is often the cause of expensive breakdowns. The composition of any tap water contains salts of calcium and magnesium, which, when heated, settle on the internal surfaces of the heating elements, forming a solid lime plaque. If you ignore the problem, the scale layer will thicken, which will lead to overheating of the thermal power plant, a decrease in pressure and, ultimately, to the failure of expensive equipment. decalcination This is not just a recommendation from manufacturers, but a mandatory maintenance procedure.
Many owners of espresso machines are wondering: what means to choose so as not to harm the equipment? The market is full of offers, from original liquids to budget analogues and folk methods. It is important to understand that coffee-machine It is a complex device with rubber seals and sensitive sensors, so aggressive chemistry can be more dangerous than the stone itself. In this article, we will discuss what is really effective and safe for your equipment.
Choosing the right reagent depends on the hardness of the water in your area and the type of coffee machine. Automatic carob machines, capsule systems and boiler units require an individual approach. Using an inappropriate composition can lead to clogging of the valves or damage to the silicone tubes. Let’s look at the basic criteria that will help you make an informed decision.
Why is the scaling formed and how it is dangerous
The process of scale formation begins long before you notice the first symptoms. When water is heated above 60 degrees, calcium and magnesium carbonates break down, turning into insoluble calcium carbonate. This sediment settles on the hottest areas - the walls of the boiler, the tubes of the TEN and the valves. Over time, this layer becomes porous but incredibly hard, acting as a heat insulator.
The main danger is the violation of heat exchange. Scale has a low thermal conductivity, which is why the heating element requires more time and energy to heat the water to the desired temperature. This leads to constant overheating of the TEN itself, since it does not have time to give heat to water. As a result, the metal burns out or deforms, requiring complex and expensive repairs.
⚠️ Attention: Ignoring regular cleaning can lead to irreversible consequences. If the scale layer blocks the narrow channels of water supply, the pressure in the system will critically increase, which is fraught with rupture of hoses or failure of the pump.
In addition, lime deposits disrupt the work of valves and electromagnetic solenoids. Small stone particles can get stuck in the moving parts of the mechanisms, causing them to jam. In automatic machines, this often leads to errors in pressure and volume sensors, which is why the device stops brewing coffee or begins to give water jerks.
Criteria for the selection of quality tools
When searching for the ideal composition for scale removal, you need to pay attention not only to the price, but also to the chemical composition. The basis of most quality products is organic acids, such as citric, lactic or sulfamine. They effectively dissolve carbonate deposits without damaging the metal and plastic parts of the coffee machine.
It is important that the composition is free of aggressive inorganic acids, such as hydrochloric or sulfuric. They can dissolve scale instantly, but at the same time destroy aluminum alloys and rubber seals. Acidity (pH) The funds must be strictly balanced for safe use in home appliances.
It is also worth considering the presence of corrosion inhibitors in the composition. These additives create a protective film on metal surfaces after cleaning, preventing re-oxidation. The presence of such components is especially important for expensive models with brass or copper boilers.
- 🧪 Material safety: The product should not cause corrosion of metals and destruction of rubber.
- 🌿 Environmental friendliness: Biodegradable components are safe for the environment when disposed of.
- 💧 No odor: A high-quality solvent should not leave a persistent chemical odor in the drink.
- 📦 Concentration: Economical concentrates are more profitable than finished solutions in the long run.
Comparison of popular brands and manufacturers
There are many brands on the market, and choosing between them can be difficult. Original products from coffee machine manufacturers, such as DeLonghi, Saeco or PhilipsThey are designed specifically for their technique. They guarantee the preservation of warranty and optimal efficiency, but often cost more than their counterparts.
There are also specialized brands of chemistry for the coffee industry, for example, Durgol or Topperr. These companies have been developing cleaning products for decades and offer versatile solutions suitable for most models. Their formulas are often more concentrated and effective against old deposits.
| Brand | Type of basic | Compatibility | Features |
|---|---|---|---|
| Durgol Swiss Espresso | Sulfamic acid | Universally. | High speed of action, odorless |
| DeLonghi EcoDecalk | Lactic acid | DeLonghi, Kenwood | Biodegradable, mild action |
| Saeco Decalcifier | Sulfamic acid | Saeco, Philips | Protection against corrosion, lack of foam |
| Topperr 3005 | Combined | Universally. | Affordable price, economical expense |
Budget analogues of domestic production also have the right to exist, but require a closer study of the composition. If the instructions do not indicate that the product is safe for food heating devices, you should not risk it. It is better to pay for a proven brand than to change the boiler.
Buy funds from specialty stores or official dealerships to avoid counterfeits that may contain aggressive impurities.
Folk methods: citric acid and vinegar
On the Internet you can often find tips to use ordinary citric acid or table cider vinegar. Indeed, these substances are acids and are able to dissolve calcium. However, the concentration of the active substance in them is not standardized, which creates risks. The solution can be either too weak or too aggressive.
Acetic acid, in particular, has a pungent odor that is very difficult to wash out of the system. Even after repeated washing with water, the taste and aroma of vinegar can be preserved in the drink, spoiling its taste. In addition, vinegar can negatively affect some types of rubber seals when used frequently.
Can pure citric acid be used?
Crystalline citric acid can be used, but only in a strict proportion of 10-20 grams per 1 liter of water. Excess concentration can damage plastic parts and aluminum tubes. Dissolve crystals need only in warm water until the complete disappearance of the sediment.
Citric acid in powder is safer, but requires careful dissolution. Undissolved crystals can get into the machine’s nodes and cause local damage or get stuck in the valves. Professional products are deprived of this drawback, as they are a ready-made, stabilized solution.
⚠️ Warning: Never use scale removal products for kettles or washing machines in a coffee machine. Their composition may contain chlorine or phosphates, which are dangerous for contact with food.
Instructions: how to properly decalcinate
The cleaning process is usually started through the coffee machine menu. Most modern models have an automatic mode that controls the supply of solution and water. Before starting the procedure, be sure to empty the drip pallet and the cake container, as well as wash the brewing unit if it is removable.
Dilute the product in the water tank according to the instructions on the package. The ratio is usually 1:2 or 1:3, but for severe contaminants, the concentration can be increased. Pour the solution into the tank and start the cleaning program. The machine will alternately supply the solution to the system and pause so that the acid has time to dissolve the deposits.
☑️ Algorithm of actions during cleaning
After the cycle with the solution is completed, the system must be thoroughly washed. To do this, you need to fill the tank several times with clean water and start the washing mode or simply spill water through the group. This is a critical step to remove the residues of acid and dissolved scale.
- 💧 Washing: Conduct at least two full cycles of washing with clean water.
- 🧼 Cleaning the parts: Do not forget to wash separately the removable parts of the brewing mechanism.
- ⏳ Time: The whole process can take 20 to 40 minutes depending on the model.
The main secret of successful cleaning is not to interrupt the process and be sure to complete it with a complete wash of the system with clean water.
Frequency of procedure and prevention
The regularity of decalcination depends on the hardness of the water and the intensity of the use of the coffee machine. If you cook 5-10 cups a day and water of medium hardness, the procedure should be carried out every 2-3 months. With high hardness of water, the interval is reduced to 1-1.5 months.
Many machines are equipped with a water hardness indicator. Correctly configuring this parameter in the menu will allow the device to independently track the amount of water passed and signal the need for cleaning. Ignore these signals can not, since the scale counter leads to a blocking of the device.
Use filtered or bottled water as a prevention. This will significantly reduce the rate of formation of deposits and prolong the life of heating elements. However, even with perfect water, preventive cleaning is required at least once every six months to remove body fat and residual plaque.
What if the machine writes "Scale" after cleaning?
If the indicator does not go out, it is possible that the conduction sensor is contaminated or there is air left in the system. Try repeating the clean water cycle. If the problem persists, a scale counter may need to be reset via a service menu or a sensor replacement.
Frequently Asked Questions (FAQ)
Can one company use a coffee machine for another brand?
Yes, if the basis of the product is universal (for example, sulfamic or lactic acid) and the instructions indicate that it is suitable for all types of coffee machines. The main thing is to observe the proportions of breeding.
How do you know if there is a scalp in the coffee machine?
The main signs: the car began to heat up longer, coffee is served weaker or slower, there was a noise when the pump was working, and the indicator of the need for decalcification lit up.
Is it dangerous to get a small amount of scale removal product into the cup?
Yeah, it's dangerous. The acids used for decalcination are toxic when ingestion occurs. If you feel a sour or chemical taste, pour the drink and continue washing the system with water until the taste disappears completely.
Can I soak the block in a scale remedy?
You can soak the metal block in a weak solution, but plastic parts and lubricant can be damaged. It is better to wipe the block with a wet cloth, and the funds from scale run through the hydraulic system of the machine.
