→ Remedy to prevent rusting :

-- Galvanisation is a process of coating zinc over iron so as to protect it from rusting.

-- Sometimes protection against rusting can be done by applying oil on the surface of things of iron, because the layer of soil does not allow the things of iron to come in contact with air or moisture. This method is practical for small tools of iron, like hammer, gardeners scissors, for cutting metals, e.t.c. but it is not favorable for huge things because at the end of very small interval of time, it becomes necessary to apply oil again.
