- If using lemon, add the lemon to the kettle, fill with water up to the marks you wish to remove and boil. Can be done a few times if kettle is particularly dirty.
- If using citric acid, boil water in kettle first and then add citric acid, let sit for approx 20 mins and voila, clean kettle.
- Empty kettle and re-fill and boil a few times before using it for drinks just to make sure all residue is gone.
