I know this is an audio sub forum but you guys might have an answer. I recently acquired a truck that was a company work truck in a filthy environment which has hardly ever been washed. Because of this the white truck has been stained a light brown color in some areas even after spending quite a while with a high power heated pressure washer going at it.

Is there a way to remove these stains without investing into a new paint job?

could try a clay bar

Put some elbow grease in er. Power washers only do so much

Spend $100 bucks and take it to a professional detail shop.
