I have a nice PPW 05 Z with a TN turbo kit, the car runs very "Rich" so I constantly have a brown stain around the Injen exhast tips.

Does anyone know what is the best way to get this cleaned up without desroying the clear coat on the paint?

I want a new bumper but hessitate without finding somthing to fix this for future brown spots on the VS2 rear.

Thanks!
