Over the weekend I washed my car after the blizzard a week ago that hit the northeast. I use the waterless and wax wash, which is mostly just spraying and wiping.
Everything came off easily, except for these pesky black speckles of “dust.” I can pick them off by scrapping with my finger (with a microfiber cloth in between my nail and car), but it leaves a very faint streak on the car that I cannot take off. The stuff that comes off also clings to the cloth and I cannot get it off.
Anyone have any idea what it is? Could it be some kind of grease from perhaps the plow that may have gone through the street?
And what is the best way to clean them without damage to the car paint?
