Chrome plating is found on everything from car bumpers to bicycle grips and serves as a way to protect a bare metal surface as well as provide a shiny coat to the metal. Chrome can scratch though, and if that should happen, the reflective quality of the plating won't be as clear. To solve the problem, one option is to polish out the scratch. Although this isn't possible for all chrome scratches, this can erase some of the lighter ones, making things look better in the process.
Clean off the chrome part with the glass cleaner and the microfiber towels to remove any dirt or grime on the part. This way you don't make the scratch worse in the process.
Apply the chrome polish to the steel wool. Apply the steel wool to the scratched surface and rub it in small circles around the scratch on the chrome. Apply medium pressure to the steel wool and make sure to keep the polish on the steel wool at all times.
