There are many ways to remove corrosion from system. But correct approach depends on the type and reason of corrosion.

1- Cut off the connection of environment with substrate by any coating system.

2- Make a system which forces your substrate to act as cathode by connecting it with the material higher in EMF series or by providing external potential.

3- Decrease the corrosivity of environment by normalizing its PH.
