Using this Deltana hinge is a breeze. First, make sure the door and the frame are clean and free of debris. Then, use the included #9 x 0.75 wood screws to attach the hinge to the door and the frame. Just align the hinge properly and tighten the screws carefully. As for maintenance, regularly check the screws to ensure they are tight. If the hinge starts to make noise, you can apply a little bit of lubricant to keep it running smoothly. When it comes to cleaning, use a mild cleaner and a soft cloth to wipe it down. Avoid using abrasive materials that could scratch the finish. And always keep it dry to prevent rusting. That's all there is to it! Your Deltana hinge will serve you well for a long time with just a little care.
