I would not use steel wheel as it could scratch the clear coat on painted SVT wheels. I have use Mother Clay bar w/ really good results. It will take some elbow grease and time so be prepared to have a couple hours of free time. It has worked well for me. My E1's look brand new. Make sure to put several coates of wax on them when your done and to keep them waxed. This will in the future make the break dust/rusty buildup come off fairly easy with just soap and water.
