Remove rust stains from car's paint?

There are rust stains on the painted metal and painted plastic bumper cover, where water has dripped down from areas of exposed rust. I have repaired and repainted the areas of exposed rust. How can I removed the rust stains, short of sanding and repainting the stained areas?

Usually polishing compound and some elbow grease works pretty well for this. A mild solution of CLR and water might get the tougher spots done, too, although I’d test a small inconspicuous area first to make sure the CLR won’t damage the paint.

I’d try a clay bar first. If that doesn’t do the trick, then the polishing compound suggested by Mustangman would be my next vote.

This product will remove rust stains from painted surfaces.

Thanks all for your advice. I had some Turtle Wax Polishing Compound on hand and it did the job.
