Stainless steel is an extremely durable surface. Although Ukinox sinks are heavy gauge and high quality (type 304), they can be scratched, and scuffed. Hard objects can scratch your sink with impact, while such scratches can be blended in using inox cream, and fine ScotchBrite pads. Do not use steel wool, or wire brush to clean Ukinox products. Daily care of your sink will avoid most stains, whereas persistent rust which is a result of an outside source such as cookware can be removed with non-abrasive stainless steel cleaners.
