Diesel soot in master bedroom ceiling/wall seams

Yahoo Message Number: 116947
Wonder if anyone has a secret potion to clean diesel soot in master bedroom ceiling/wall seams? There's a couple of screws that hold up the ceiling between the lights and one seam forward of the window on the curb side that are stained with diesel soot. Nothing appears to break it down to clean it. Don't want the stain to leach farther out though. Anyone got a sure way to clean it up? Thanks!

I have the same issue, seems the exhaust is being sucked back into the radiator. Looking at the tail pipe its black next to the radiator side and clean on the opposite edge. Took it off and put a sweep 45* tail pipe on which I hope stops this.

Folks, to help stop this, keep your windows and vents closed during travel. There is negative pressure generated inside the coach while in motion. Thus, any exhaust will find its way inside. Check your engine access seals for any voids. I have had several coaches come to me for flooring and upon inspection of engine access, I have found the seals to be compromised. FYI

I had a similar issue a couple of years ago, caused by pin hole leaks in the muffler which was promptly replaced. I never smelled any exhaust fumes in the coach.

I found a 50/50 solution of Simple Green and water worked the best, but you can experiment with different concentrations. I mixed about a pint of solution at a time and working on small areas at a time, dabbed it on with a clean rag and where necessary, used a small soft bristle brush to work it in. I then dabbed it off with a light colored towel so I could see how well it comes out, always using a clean area of the towel(s). At first, the towel gets pretty black but after a few times going over an area, most of the soot will come out. (Note that I never eliminated all traces of the soot, but did remove the vast majority.) When satisfied with the results, I dabbed the same areas with clean water to eliminate any residual Simple Green solution and then let it air dry.
