Copper Sinks from Rustic Sinks are finished with a patina that is “fired” in the material and gives them a weathered or “aged” appearance. If you scrub and polish-or use acid-based or abrasive products on them, it will damage the patina finish. Just rinse your sink with water after each use, give it a thorough cleaning with mild soap from time to time and it will give you a lifetime of enjoyment.
