Cleaning inside an electric kettle is simple: fill it with water, bring it to a boil, and then pour the water out. If there's still buildup, repeat the process.
This method leverages the boiling water to loosen mineral deposits, commonly limescale, that accumulate inside the kettle over time. If the buildup is significant, consider using a descaling solution like vinegar or lemon juice diluted with water for a more effective cleaning.
