Using this Deltana hinge is a breeze. First, make sure the surface where you'll install it is clean and flat. Then, align the hinge with the door or cabinet and use the provided #12 x 1-1/4' wood screws to secure it. When opening and closing the door or cabinet, do it gently to keep the hinge working smoothly. As for maintenance, you can wipe it with a soft, dry cloth regularly to keep it clean. Avoid using harsh chemicals as they might damage the solid brass finish. If you notice any loose screws over time, just tighten them up. This hinge is built to last, but with a little care, it'll serve you well for years.
