What are polished metal mirrors made of?
Polished metal mirrors are typically made from a sheet of glass paired with a reflective metal coating, then finished with a metal frame (or metal-look surround) that’s buffed to a high shine. While the face may read as “metal,” most home décor mirrors still rely on glass for clarity and stability, with the metallic effect coming from the backing and the surrounding trim.
Common materials used in polished metal mirrors
Glass + metallic reflective layer: The mirror itself is usually glass coated on the back with a reflective layer. Historically this was often silver; many modern mirrors use aluminum for reflectivity and durability. Protective paint layers are then applied over the metal coating to reduce scratches and corrosion.
Metal frames (real metal): The “polished metal” look most often refers to the frame. Popular choices include stainless steel (naturally corrosion-resistant), aluminum (lightweight), brass (warm-toned and classic), and sometimes iron or steel with a plated or polished finish.
Plated or coated finishes: Some frames are made from a base metal and then electroplated (for example, brass-plated steel) or coated (such as PVD-coated stainless steel) to achieve a specific tone like gold, champagne, or chrome. These finishes can help maintain shine and resist tarnishing.
Alternative constructions: Budget-friendly “metal” mirrors may use MDF or resin frames wrapped in metallic foil or coated with metallic paint. They can look convincingly polished, but they’re not solid metal and may be more sensitive to chips and moisture.
How to tell what yours is made of
Check the product description for terms like “stainless steel frame,” “brass plated,” or “aluminum mirror.” Weight is another clue: solid metal frames usually feel heavier and colder to the touch than resin or MDF. If it’s in a humid space (like a bathroom), stainless steel, aluminum, or well-sealed plated finishes tend to hold up best.

FAQ
How do you clean a polished metal mirror frame without dulling it?
Dust first, then wipe with a soft microfiber cloth lightly dampened with water or a gentle soap solution. Dry immediately, and avoid abrasive pads or harsh chemicals that can scratch or haze plated and polished finishes.
