One of the better, and less labor intensive ways is to use the good ole dishwasher, if your house is so equipped. Just use the regular dishwasher-type soap, and the "pots-n-pans" cycle, if ya got a choice. Turn off the heated dry, or catch it before that part of the cycle starts. Does a  wonderful job. At least it has for me, so far. Great for wire wheel covers, too.

  One thing, though. Make sure the wife / SO doesn't find out. Could be trouble.

  What can I use to get the brake dust off my plastic hubcaps on my 91GL? I've tried brake cleaner, carb cleaner, orange glow, palmolive and still have residual. Don't want to remove the finish. Thanks, guys.
