Black phosphatized products have intentionally not been painted because it is the surface irregularity the characteristic which makes them so special. The daily use will form stains (wine, coffee, etc.) forming a patina which renders the surface even more beautiful. When delivered the surface black phosphatized has undergone a final treatment with beeswax. Please clean it first with a dry rag in order to remove traces of oxydation and wax. To clean it use a non aggressive/soft detergent as it would be wood. Twice a year, we suggest to impregnate the surface with beeswax, removing it after one night as described above.
