How do you wash tawa?

Could you please elaborate on the process of washing a tawa, a flat pan commonly used in Indian cuisine? I'm curious about the specific steps and any techniques or precautions one should take to ensure the tawa is properly cleaned and ready for the next use. Do you start with hot water or cold? Do you use soap? How do you remove any stubborn stains or food residue? I'm particularly interested in preserving the non-stick properties of the tawa while cleaning it.
