So I washed the car today and I noticed that some areas, especially the hood, there was still some faint dirt stains or the paint looked yellowish and not perfectly white after going over it twice, ie. soap mitt, rinse, soat mitt again.
any tips on how to get rid of the stains and prevent them? also I've noticed that the white paint attracts many little black or other colour stains that's pretty hard to get off or doesn't even come out after washing with a mitt (tar?).
btw its flat white paint, with no metallic in it.
edit, heres the best pics I have for now, it's very hard to capture since its white surface and the spots are very faint so my phone couldn't focus properly.
