Chrome is most commonly plated onto other metals like bronze or aluminum to make them more resistant to corrosion and more visually appealing. Chrome is naturally gray in color, but can hold a very lustrous shine if polished. This is the way we usually see chrome when it is plated. However, if you prefer the look of a satin finish metal, you can sand down the polish on a chrome object to give it a more brushed or satin look.
Soak your sand paper in a bucket of water for 10 minutes before sanding the chrome surface.
Wet sand the chrome with a 220-grit sand paper. This will remove the shine of the polish and roughen the surface of the metal.
Wet sand the chrome with a 400-grit sandpaper. This will smooth out any roughness on the surface of the chrome and give it a satin luster.
Wipe down the chrome with a damp cloth to remove any loose sanding dust.
