Can't keep back of car/decklid clean

[Atlantamustang77]

Hey guys new poster here. I have a 16 CO GT base package with spoiler delete. I have noticed I can clean the car and after driving down the road and back the back end esp the black trunk decklid gets covered in what looks to be just regular dust maybe a mix of brake dust. It wipes right off but it is driving me crazy. It gets all over tail lights as well. Anyone else experience this? I am thinking of maybe swapping out the back pads to see if that helps or I was also thinking it was from not having a spoiler. Help.

Is the dust oily? An old family volvo was burning oil, and although not after one drive, after a little the backside of the car had the burnt exhaust oil clinging to it.

It's not brake dust, don't waste your money. It's just ordinary road dirt collecting due to the aerodynamics of the car. We all deal with it.

It's just normal dirt due to aerodynamics of the air going over the top of the car, over the spoiler, coming back to smack the decklid. It's a horrible dust-magnet and just looks significantly worse due to the black glossy sheen where you'll see every little spec possible.

There's not really much you can do outside of constantly cleaning it or going to a different look like a matte/wrap or different decklid that won't show the dust/dirt like the gloss back which is just about the worst material/color combo for it.

Thanks for the response guys. I first was worried it was coming from exhaust but it is dry dust and exhaust is clean as a whistle. I guess I'll just have to get used to it and dust it off every so often. Trying not to be so OCD but that glossy decklid will test you.

yup im thinking of getting rid of my blank decklid for the matte one from mmd, will be much easier to clean!

have your vehicle ceramic coated. it resists dirt etc easier and also makes cleaning a hell of a lot easier

Every inch of my car is ceramic coated, and while it's easier to clean...still a dust magnet.

Same problem on my GT. I just try and keep the car waxed, and quick detail that rear decklid from time to time.

THIS^^ I got ceramic pro and can't say enough about how good it works.

It's the aerodynamic of the car. Road dust likes to build up on the back end of the car.

Kind of, but very much no. The air over the vehicle is largely unbroken and very fast. Behind the vehicle you will have a low pressure cortex created largely by the turbulent air from underneath. This causes dust and road grime to swirl back up and stick to your ass.

You can reduce it with a spoiler and diffuser combo which would push the negative vortices out further, but just wash your car.

Yeah I think your right about it coming from up under the car because it gets all over the bumper you just can't see it like you can on that glossy black. I figured too that it could be worse because I don't have a spoiler. I keep it clean, it seems to stick out worst when it is clean almost looks like a glittery dust/sand that clings to it like a magnet like you guys said. Not that big a deal I just hate having to dust it off all the time
I checked the matte black one out by MMD, looks pretty good. I may go with that one.

Everyone's nailed it; it's the aerodynamics of the car and we just have to live with it.

If you think it's bad on a fastback, it's worse on a convertible, especially with the top down.

Each time I drive mine, I wipe it down before I put her to bed--it just goes with the territory.

All this wiping of dust going on lol. I can just picture swirl city

Leave the dust! The only time it should ever be wiped off is when your washing it. Does more harm than good.
