Polished brass with protective, transparent varnish for indoor use. For cleaning and maintenance only use a cotton cloth dampened with water or specific neutral products for varnished surfaces. Do not use abrasive cloths, solvents, alcohol or strong detergents. Dry the surface thoroughly in case of standing water. Samples images are an indication only and do not replace the use of real ones, since it is not possible to guarantee a reproduction identical to the original.
