Kalstop is mixed with the water that goes into the device's boiler (5 liters of tap water one Kalstop ampoule). This mixture can replace deionized water (continuous use).

For devices with a continuous refill boiler, the above procedure must be followed every time for the long-term operation of the device.

Kalstop can be put directly into the device's boiler to clean it from lime scale formations.

• 2 ampoules in 200ml of water in a device that has been turned on.
• Once the readiness light turns on, turn off the device and leave the mixture for at least two hours.
• Rinse the boiler and you will see a brown liquid with lime scale residues coming out, indicating an effective cleaning has taken place.

This process is recommended to be repeated every 6 months, although the cleaning frequency depends on the area's water.
