Yesterday morning I took a short trip and the streets and roads were mostly frost covered from freezing fog and moisture. Around here they spray a lot of the roads with a deicer of some sort and that combined with melting frost made a real mess of my rear window and the Jeep's back end. The deicer stuff is black and when the moisture dries it leaves a grimy, powdery residue. I've seen other SUVs that have the same problem. Guess the aerodynamics of the car create a vacuum in the back and it just sucks up stuff and sticks it to the car.

Any ideas for a way to minimize or eliminate this phenomenon? I don't have the rear splash guards and I wonder if they would help.

This is just a reality of SUVs, or any wagon-type vehicle with a vertical backend. Nothing you can do to prevent it.

Yup, as stated above, nothing you can do but get used to it. (sorry)

This is afterall why SUV's/CUV's/hatch-backs have rear wipers and sedans do not…..

WAsh that stuff off regularly. I assume it's the same brine used here too. We can see secondary roads with black stripes on them well into summer. It actually stains some kinds of asphalt. I don't notice it on highly used highways. What in the world is it doing to our water let alone our vehicles?

It's nice to have the main roads free of ice but that is some nasty stuff they put down. My Latitude doesn't have an auto release on the lift gate so I have to use my hand to open it. Wind up with the grimy stuff on my fingers. We have a car wash that has switched from the beater brushes to a touchless system that also sprays the underside of the vehicle so I can keep things reasonably clean. Would be neat if some aerodynamic engineer would come up with some kind of flaps you could deploy on wet days that would eliminate the problem.

Keep a good coat of wax on the vehicle.

My recommendation: Zaino Bros. polish

As a driver of SUVs for many years it becomes a fact of life ,I think one uses more washer fluid on the rear window than the front.

It's interesting, I never noticed that happening on the back of my XJ, but it was shaped like a box. My wife's Audi allroad gets filthy just opening the garage door. Definitely comes down to shape & aerodynamics.

I put a coat of wax on the Jeep the second day I had it at home. I'm a Meguiar's fan myself and a couple of shelves in my garage are full of Meguiar's car care stuff. I'm especially impressed with the new White (which I used on my previous car) and Black wax formulas. I'm a bit of a stickler for keeping my vehicles clean and at trade in time I always get top dollar.

There's a product called Rejex that goes on like wax but forms a polymer coating over your paint surface. It makes it difficult for dirt, bugs, tar, etc . to stick to your vehicle. Anything that does get on the surface wipes right off easily.

Sounds like my old VW GTI, its rear end was a magnet for crap!!! (pun intended lol)
