Our finely crafted bronze sculptures require minimal care and will last for generations. Like any item left in the elements, oxidation from sources such as pollution, bird droppings, tree sap or bug tar can build up on the surface. Prolonged exposure to moisture can cause oxidation, turning an unprotected surface to a green patina over time. You can either let your sculpture age gracefully to your preferred look, or you can do occasional maintenance to preserve the original finish. We recommend occasional, gentle cleaning to preserve the beautiful finish. There are some great products that can help you achieve this. A neutral, diluted soapy solution applied with a soft, clean wash cloth is great for occasional cleaning. After cleaning, a high-grade wax or clear coat lacquer spray can be applied for protection. Prior to any full cleaning, always test an inconspicuous area first.
