Using these Deltana hinges is easy. First, make sure the cabinet surface is clean and dry. Align the hinge with the cabinet door and frame, then use the provided #7 x 3/4' wood screws to attach it firmly. When opening and closing the cabinet door, do it gently to avoid unnecessary stress on the hinge. As for maintenance, simply wipe the hinge with a soft, dry cloth regularly to keep it looking great. Avoid using abrasive cleaners as they can damage the fine finish. If you notice any looseness, check the screws and tighten them if needed. With proper use and care, these hinges will serve you well for a long time.
