Using these Deltana hinges is easy. Just align the hinge with the cabinet or furniture where you want to install it, then use the #7 x 3/4' wood screws to secure it in place. Make sure the surface is clean and dry before installation for a better hold. When it comes to maintenance, a simple wipe with a soft, dry cloth regularly will keep it looking great. Avoid using abrasive cleaners as they can scratch the brass finish. If you notice any loose screws over time, just tighten them gently. These hinges are built to last, but with proper care, they'll serve you well for years in your kitchen or on your furniture.
