A real cheap de-scaler can be made by boiling rhubarb leaves. The oxalic acid contained in these leaves is rather dilute but it will work. Even cooking the root end of the stalks will release the oxalic acid.

You can buy oxalic acids crystals at a chemists as well. Caution is advised...do not inhale the fumes or get the acid in your eyes. Concentrated oxalic acid is corrosive and poisonous. Wear rubber gloves.
