I have these small stains on my bumper and near the bottom of my trunk lid. They are black and some are this orangish color. I think they are tree pollen and exhaust residue stains. My car is a garage queen and is washed one a week it only goes outside on weekends. I tried re washing the area and QD a couple of times no luck, I have AIOx1 and SGx5. I figured that with the Klasse on there this would not happen. My question is what can I use to remove these stains without removing the Klasse if it is possible and I also have given it thought to Aio again but don't want to use it if I don't have to.
