Using the Deltana 4 x 6 hinge is easy. First, make sure your door and frame are clean and free of debris. Align the hinge with the pre - drilled holes on the door and frame, then use the provided #10 x 1-1/4' wood screws to secure it in place. When opening and closing the door, do it gently to avoid putting too much stress on the hinge. For maintenance, wipe the hinge regularly with a soft, dry cloth to keep it looking its best. If you notice any dirt or grime, you can use a mild soap and water solution, but be sure to dry it thoroughly afterward. Avoid using abrasive cleaners as they can scratch the finish. This hinge is made of solid brass, which is durable, but over time, it may develop a natural patina. If you prefer the original look, you can use a brass polish to restore its shine.
