  • Remove diesel smoke spots?

    My 2007 Yukon is covered with black spots after meeting a diesel truck with dark black exhaust so thick cars were stopping due to lack of visibility in the cloud. The spots do not come off with Invisible Glass and only smear when I used the windshield washer. My wife tried Dawn dish soap in some warm water but the spots are very hard to remove. What do I do to remove these spots without harming the finish? Thanks for your help!

    Just clay bar the vehicle, paint, glass, etc. and itll be fine.

        Claying should do it.
        quality creates its own demand

            Going to be unpopular for saying this..... Over apply #7 sealant on the spots. the petrol/oil solvents dissolve the spots in a flash. of course a wash and rewax is in order after that. Otherwise, yes, the clay bar is a miracle..
