Using your Deltana hinge is easy. First, find the right spot on your cabinet or door where you want to install it. Make sure the surface is clean and smooth. Use the #7 x 3/4' wood screws provided to attach the hinge securely. When opening and closing the cabinet or door, do it gently to avoid putting too much stress on the hinge. As for maintenance, you can clean it with a soft, dry cloth regularly to keep it looking shiny. If it gets dirty, you can use a mild soap and water solution, but make sure to dry it thoroughly afterward. Avoid using abrasive cleaners as they can scratch the finish. Also, check the screws from time to time to ensure they are tight. If you notice any looseness, simply tighten the screws with a screwdriver.
