You will need
- A bottle of any type of Vinegar
- Wipe down the surface of the kettle with warm water and dry with a cloth.
- Fill a kettle ¾ full of equal parts vinegar and water.
- Close the lid and bring to the boil.
- Rinse a few times to clear out the dislodged limescale.
- Boil again with water only and rinse again to remove the smell and taste of vinegar (no one wants vinegar-infused tea).
