    Set your kettle to boil with Coke in it. Leave your kettle and the boiled Coca-Cola to cool down for about 45 minutes. Then rinse the Coke out and wash the kettle as usual.

    Can I use lemon juice or does it have to be fresh lemons?
    Community Answer
    You can use either, but fresh is better because there is more acid in the juice.
  • Question
    Will bicarbonate of soda or baking powder alone dissolve limescale? Do I need to mix lemon juice or vinegar with the bicarbonate of soda?
    Community Answer
    Limescale dissolves in acids such as citric acid (lemons) or acetic acid (vinegar), not in alkalis such as bicarbonate of soda or baking powder. Mixing lemon juice or vinegar with bicarb will neutralize the acid, so that won't work.
