Also I noticed my back bumper is slightly covered with black soot.
Should I be a bit worried?

Yeahhhhhh... I have a Monterrey Blue 370Z and the back is hazy, I can keep the car clean for... 30 minutes, maybe an hour if it was raining when I washed the car, then drove around in the rain.
But a car wash takes all that crap off immediately
