By Age of Bronze
In regards to the bronze restoration of your statue, the bronze should be treated by a qualified metal conservator who will reduce or remove the active corrosion, stabilize the surface, and integrate a patina to match the existing one if there are any traces of the original one remaining. Once treated, if you decide to keep it outdoors, the bronze statue should have an annual cleaning which would involve a washing of the surface, and a cold application of a clear paste wax that's recommended for outdoors.
