How do you remove Exhaust Stain from the rear bumper?

[Iain H]

On my recently acquired white boy racer car, with the obligatory big exhaust, there is an unsightly exhaust stain on the rear bumper. Does anyone have any ideas how I can get rid of it?

I would try the following.

Wash the area then try some Bilt Hamber Auto Clay.

If that does not work something like Klasse AIO / Carlack 68

If that fails something like Bilt Hamber Sufex HD which can be cut regarding strength.

If that fails maybe it is time to seek a professional with a rotary and polishes etc.

As already said above, a decent paint cleanser should remove.
