Exterior Cleaning:
Unplug the kettle and allow it to cool completely. Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
Interior Cleaning and Descaling:
Regular descaling is recommended to maintain performance and prolong the kettle's lifespan, especially in hard water areas.
- Remove the anti-scale filter by pulling it upwards from its slot near the spout. Rinse it under running water.
- For descaling, use a commercial descaling solution suitable for kettles, following the product's instructions. Alternatively, you can use a mixture of white vinegar and water (1 part vinegar to 2 parts water).
- Fill the kettle with the descaling solution or vinegar mixture to the maximum level and let it stand for 30 minutes to an hour (do not boil the vinegar solution).
- Empty the kettle and rinse thoroughly several times with fresh water.
- Reinsert the anti-scale filter.
