i used Mothers mag and aluminum polish to clean them(see pic). if they arent very bad, you can just do alot of rubbing with the polish and a handtowel. Since mine were so bad i first took a WELL USED scotch brite pad, use a worn one since it will not be near as abrasive(will still leave scratches, but they can be buffed out with the polish). do a small area at a time to check the progress. Mine still need more work, but it looks alot better.. now to tackle the passenger side
Polish (about $5)
