Before we begin there are two details we must address. If the rust has eaten through the chrome polish, this will not work. You also need to confirm that you have a true chrome finish. Make sure it is not just plain metal that has been painted with chrome coloured paint. Once these two factors have been addressed and confirmed we are ready to begin. You will need to assess the extent of the chrome rust and notice the depth of the rust. You can simply clean the chrome with soap and water so you can see the rust areas...
