6. Maintenance
- Cleaning: Always unplug the kettle and allow it to cool completely before cleaning. Wipe the exterior with a damp cloth. The interior can be hand washed with mild soap and water. Do not use abrasive cleaners or scouring pads.
- Descaling: Over time, mineral deposits (limescale) may build up inside the kettle, especially in hard water areas. To descale, fill the kettle with a mixture of equal parts water and white vinegar (or a commercial descaling solution). Let it soak for 30 minutes to an hour, then boil the mixture. Discard the solution and rinse the kettle thoroughly several times with fresh water.
- Storage: Store the kettle in a dry place when not in use. Ensure the power cord is neatly stored in its hidden compartment.
