Using this Deltana hinge is a breeze. First, find the right spot on your cabinet or door where you want to install it. Make sure to align it properly and use the #7 x 3/4 inches wood screws provided to secure it firmly. For best results, use a screwdriver that fits well with the screws. When using the hinge, you'll notice a smooth swing for your doors and cabinets. As for maintenance, you can wipe it down with a soft, dry cloth regularly to keep it looking good. Avoid using harsh chemicals or abrasive cleaners as they might damage the finish. In case you see any dirt or grime, a mild soap and water solution can be used, but dry it thoroughly afterward. Also, check the screws from time to time to ensure they are tight and the hinge is secure.
