Fingerprints do not show as they will on stainless steel and other metals. For basic cleaning, simply use soap and water. Copper has a "living finish" and its patina will continue to develop character over time, meaning it may become a richer, darker color. Due to the handcrafted nature of this product, it will vary in appearance, finish, texture, hammering and other details. Dimensions may vary up to 1/2". We strongly suggest you use the actual piece before making any installation cuts. Made with the highest standards of quality and creative design, Novatto sinks add artful function and charm to any bath or powder room. Just add water and enjoy the limited lifetime warranty.
