"Hi, drain out all the water from the bottom of the pan and then put a big bottle of Kilrock limescale remover into the pan, leave it for a couple of hours then flush, you might need to do it a couple of times depending on how bad the limescale is. Wear gloves and open windows as the chemical isn’t good for your skin. Don’t put anything else in with the Kilrock as that’s dangerous."
