Maintaining and cleaning outdoor metal wall art made of Corten steel or powder-coated aluminium is relatively simple and straightforward.
For Corten steel, you can use a soft-bristled brush or cloth to remove any dirt or debris from the surface of the metal. Avoid using abrasive materials or cleaning solutions that contain acids or chemicals, as this can damage the protective patina that develops on the surface of the steel. Instead, you can simply rinse the steel with water and allow it to air dry.
For powder-coated aluminium, you can use a mild soap and water solution to clean the surface of the metal. Avoid using abrasive materials or cleaning solutions that contain solvents, as this can damage the powder coating. After washing, rinse the aluminium thoroughly with clean water and allow it to air dry.
