Enameled sinks may be found in either the kitchen or bath. Coats of enamel paint on such sinks are “baked” onto a steel or cast-iron sink at high temperatures. Enamel is a long-lasting finish, but it’s not indestructible.

Abrasive cleansers and pads will scratch the enamel and can strip it right off the metal if applied with too much “elbow grease.” Instead, use hand dishwashing liquid or liquid household cleaner applied to a sponge or cloth. Soak dried food off the surface by placing a wet sponge or cloth on it for several minutes. Scrub with a white nylon-colored pad only when necessary.

Avoid dropping heavy or sharp objects into your sink. Doing so may chip the enamel, exposing the underlying metal to corrosion. A rusted sink eventually must be replaced because rust-through holes cannot be repaired.

Sinks made of coated metal should not be confused with porcelain sinks, which are made of clay that is molded and fired in a kiln.
