How Long Does Bronze Restoration Last

I’m looking into getting a small bronze statue I have on my porch restored to its original colour. I bought it about 5 years ago, and now it is completely covered in green patina. How long does the restoration usually last before it starts to deteriorate again?

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.
