OK, so what is this stuff that appears 5 minutes after a wash on my shiny white C63? Is it brake dust or exhaust soot?

_AMG_

That's a vague question. Did you see it after driving the car?
Some pics would help.

You don't have a clue what it is do you? It's the tire shine that you put on the wheels Think about it for a second.......LOL

The C63 creates alot of wirble at the rear end when driving.

Yuille36

What are wirbles? Are you referring to rubber marbles?

HBC350

Negative. And every white C63 I've ever seen has the rear bumper covered in black dust/particulate.

HBC350

Wash the car, drive it around the block to get some of the water off, rear bumper already has black dust on it.

GHAZAN

its called dirt, dust, soot, etc...why drive your car around before drying it, it gets dusty

AMGC60-3

Roger on that!!!

Its the tires kicking up dust and debris. The rear bumper gets dirty very fast.

HBC350

Funny. I'm not f-ing 12. It's not dirt, either. It's either exhaust soot or brake dust. Just wondering which. I'm thinking brake dust because there seems to also be an accumulation of metallic particulates (like fallout) on the bumper surface that need to be taken out with clay. Just was wondering what the smart people here had to say.

have you had your secondary cat or/and resonator removed recently? my clk would spit out some oil after i had those two removed.it only did this for a little while and then went away.

Yuille36

I would say that it's probably a combination of the two. At first, I thought it was tire shine kicking up, as these car washes around here just slap the tire gloss on with a paint brush I fu**ing hate it. This last time they did the drivers side but forgot the passenger side. Idiots ...I rather apply it myself.

Yep, I have the same problem with my white C63... I think it is the whirlwind when driving that picks up all the crap such as rubber dust, brake dust, road dirt and maybe even exhaust soot and lands it on the rear of the car.

Exhaust soot?

ZephyrAMG

there are a few threads on this and people have been complaining about the dual exhaust and the exessive amount of exhaust soot that accumulates due to the turbulance in the tail and the collecting all over the rear. EVERYTIME i wash and come back after 1 drive it looks like the inside of a chimney on mine.

jsc1234

i get this too! i thought it was just my car. i dont even have to drive around it happens when i start my car to drive it in the garage you can clearly see the black dust or whatever it is

FastDonzi

thats why you need one of these.

ZephyrAMG

But all you can find now is cheap plastic handle....

eagle_lex

mine gets it. i just thought it was dust, dirt, and exhaust. its no biggie really. if you notice your rear fenders get it down low as well. just wash her after you drive her a day or two.

MiamiAMG

Really? That sux. I'm glad i still have mine with the wooden handle.

FastDonzi

i saw them with wooden handle at pepboys.$20

ZephyrAMG

Damn thats a relic....I'd snag one of those beaut's if I saw one...

grindclean

I think it comes from the tires, due to the amount of rear tow in. I get it even on an interstate run when brakes are hardly used. This is why it is also found behind the rear wheels down low and away from the exhaust. Seems like static holds it to the paintwork making it hard to remove with a duster. I have to use detail spray.

AlexCim

its exhaust soot. can't avoid it, blame the car's aerodynamics.
