Limescale deposits in coffee machines
Coffee machines can develop limescale deposits over time, especially in areas with hard water. These deposits can affect the function and lifespan of the appliance. Regular descaling can prevent this.
Signs of possible limescale deposits
The following signs may indicate limescale deposits:
- Extended brewing time
- Smaller amount of water per brewing process
- Changes in noise development
- Visible limescale deposits in the drip tray
- Descaling indicator lights up (on appropriately equipped devices)
Note: In case of malfunctions, consult the operating instructions or customer service.
Recommended descaling intervals
The frequency of descaling can depend on the water hardness. Many manufacturers provide the following guidelines:
- Soft water (0-7°dH): Approximately every 3-4 months
- Medium water (8-14°dH): Approximately every 2-3 months
- Hard water (15-21°dH): Approximately every 4-6 weeks
- Very hard water (>21°dH): Possibly monthly
Important: Please refer to the specific recommendations of your device manufacturer, as these may differ.
Suitable descaling agents
Various products are available for descaling coffee machines:
- Manufacturer-specific descalers
- Universal descaler for coffee machines
- Descaling concentrates for dilution
Important characteristics of a suitable descaler:
- Approved for coffee machines
- Compatible with various materials (seals, plastics, metals)
- Food safe
- Rinses out completely without leaving any residue
Our 1L descaling concentrate with color indicator is designed for use in coffee machines. The color indicator helps monitor the descaling process. Please refer to the instructions on the product label.

Step 2: Start the descaling program
Follow the instructions in your machine's user manual. Many appliances have an automatic descaling program.
Step 3: Observe the exposure time
Some manufacturers recommend a contact time. Follow the instructions in the user manual.
Step 4: Rinse thoroughly
Rinse the device several times with fresh water, as described in the operating instructions.
Step 5: Clean the milk system separately
The milk system usually requires separate cleaning with suitable products.
Important: These steps are general in nature. Always follow the specific operating instructions for your device.
Information on home remedies
Various home remedies for descaling are recommended online. Please note the following:
- Vinegar: Not recommended by many manufacturers, as it can damage seals and leave an odor.
- Citric acid: Can form poorly soluble compounds when heated with lime.
- Baking powder: Is alkaline and therefore not suitable for descaling.
Special descalers are usually tested for material compatibility and designed for use in coffee machines.
Preventive measures
The following measures can help reduce limescale deposits:
- Use of water filters (if recommended by the manufacturer)
- Regular use of the machine
- Daily emptying of the water tank
- Use soft water if available
Common mistakes during descaling
- Infrequent descaling
- Incorrect descaler dosage
- Insufficient rinsing
- Cancelling the descaling program
- Neglect of the dairy system
Summary
Regular descaling can help maintain and preserve the functionality of coffee machines. Using suitable descaling agents and following the manufacturer's instructions, this process is usually straightforward.
Safety information: Use descaling products only according to the manufacturer's instructions. Observe the safety data sheets and warning labels on the products. Keep cleaning agents out of the reach of children. In case of skin contact, rinse thoroughly with water.
