Rusted wrought iron can often be repaired with a wire brush, steel wool, or sandpaper to remove the rust and expose the underlying metal. If the rust has penetrated deep into the metal, then the metal might need to be replaced.

Yes. Wrought iron can be repaired if it is rusted. However, the repair process will depend on the extent of the rusting. If the wrought iron is only mildly rusted, then a simple cleaning and coating with a rust-inhibiting paint may be all that is necessary. If the wrought iron is severely rusted, then more extensive repairs may be necessary, including sandblasting, priming, and painting.
