Fill your kettle with water and add a few drops of dishwashing liquid, baking soda or vinegar. Use a dishcloth to scrub out the interior and to help loosen any deposit buildup and rinse thoroughly. If you have mineral deposits, descale by adding a white vinegar and water solution to your kettle overnight. Wash with a clean dishcloth the following morning. To help prevent deposit buildup and rust, don’t leave water in your kettle when it’s not in use.
Electric kettles shouldn’t be immersed in water. To clean the exterior, use a damp cloth. A clean, soft cloth should be used to dry and polish your kettle. Most manufacturers don’t recommend using abrasives or scouring agents of any kind. Some electric kettles, like the 1.25 L Electric Kettle from KitchenAid, have removable mesh filters to trap scale deposits for cleaner water. The filter should be cleaned periodically under hot water with a soft brush or cloth to help loosen deposits.
