Using the Deltana Solid Brass 3 - 1/4 - Inch Baseboard Door Bumper is easy. First, find the right spot on your baseboard where the door hits. Then, simply install it according to the included instructions. It's designed for a hassle - free setup. When it comes to maintenance, a simple wipe with a soft, dry cloth every now and then will keep it looking great. Avoid using harsh chemicals or abrasive cleaners as they could damage the brass finish. Also, be careful during installation to not scratch the bumper or the baseboard. If you notice any issues with the installation or the product itself, contact the retailer for assistance.
