Handcraft finishing created by De Castelli for indoor and outdoor use. Brushed aluminium is obtained manually by using Scotch-Brite. If used outdoors, the satin surface may be affected by marks or rust spots, due to external agents found in the air or in the surrounding environment. Differences compared to the sample provided are not to be considered as a manufacturing defect, but as a feature of the manual processing, that may be susceptible to variances in color and homogeneity. For cleaning and maintenance only use a cotton cloth dampened with water or specific products for stainless steel. Do not use abrasive cloths, solvents, alcohol or strong detergents. Dry the surface thoroughly in case of standing water.
