Dirt stain remover help

[Balthezor]

Hey all. I’m detailing my inlaws white car. This car has never been washed in the past 5 years and its always outside. There were a lot of dirt and grime on it. Took awhile to wash it with a pressure washer.

Thing is. There are left over dirt stains or grime on the edges of some curves. I clayed and polished that area with no luck. Anything out there I can use to get rid of these?

Did you use a iron remover?

If not, I would guess the dirt and grime might be embedded contamination.

Yes I did!
