Ceiling rust stains
While sitting on the sofa in my 1341 Sea Breeze this past trip I notice that it appears that screws, or some fastener, under the ceiling "carpet" of the ceiling are rusting. There are several small circular dots of brown staining in a perfect straight line in the ceiling of the slide out. There are several that I see in other areas of the living room, and I assume they are rusting in response to moisture in the coach while in storage. We have begun putting "damp-rid" buckets in areas of the coach to avoid musty smells and molding in closets in bedroom. I was first concerned that the smell and mold were indicative of a leak, but thanks to MUCH rain this past week, I am confident that it is not leaking. I have had the roof resealed in the past year too, and with the solid, one piece fiberglass roof I feel pretty confident it is just due to humidity.
Now wondering if it is advisable to use a rust remover, like rust-aid, to remove the stains, or do as the DW suggests, just leave it alone.

Just went out and checked mine. No stains.
I would like to know what you used for sealing the end caps.

Done by RV service tech, used Dicor. Then had skylight in shower reset due to leak and they used Dicor as well.
Don't know what is so special about Dicor but everyone uses and recommends it that I speak to.
I also used it to seal the "belt line" around the bottom of the wall panels. I have some swelling at the bottom of panels so sealed along there as best I can. I see that swelling on many Nationals that I have seen, hope it will not lead to delamination.

I have never seen Dicor or Eternabond. I thought Dicor was for spot patching, like around a vent or antenna and Eternabond was more like a wide tape.

I will be very surprised if you can remove the rusty screw marks.
In my experience I have never found anything that works on that fabric.
If somebody else has, I would sure like to know what it was.
Trying to replace that stuff would be a serious project.
I would consider some cosmetic ceiling moldings to cover them if you cannot ignore them.

Bookmarked. Thanks.
What about using some of those rose bud washers or retainers.

rusty ceiling screws
The rose bud screws are called rosettes and can be purchased at HD.

They are barely noticeable, I just happened to be sitting there staring at ceiling when I noticed. But, we have been successful in removing stains on the ceiling material with a solution of oxy-clean. The mixture was suggested for removal of stains from leak, which we had around the shower skylight. I have considered removal of the material in the shower area, haven't gotten bold enough to try it yet.

We recently bought an electric dehumidifier for our coach at Home Depot. It is a 120 Volt unit with about a 2-gallon bucket. It is about the size of a paper shredder - just right to fit behind the dinette table/chairs.
At first I started checking the bucket to see if it was actually collecting moisture - our coach is pretty dry with few, if any leaks. A couple of days after I put it in, I checked and the bucket was full! I dumped it and kept on checking. Every two days, the bucket was full.
Humidity outside varied from 40% to 98% (when it was raining). A humidity gauge within the coach showed a pretty steady 80%.
Getting tired of dumping buckets, I finally made sure the grey tank was clean and empty. Then I set the dehumidifier up on the chopping block atop the second sink and ran it's drain hose into the sink. I ran a 50' garden hose over the bank to an empty area, then pulled the grey tank dump valve.
I didn't know how much moisture was in that coach until my shoulder got sore dumping buckets. The Dri-Z-Air I had in there wasn't really doing squat!

We had roof leak problems that stained the ceiling. The product that we found to work was RESOLVE CARPET STAIN REMOVER. It may take a couple of treatments to remove the stain; but worth the effort.

On my 05 Dolphin I noticed what looked like brown stains in the living room slide sealing and above the navigators seat. I turned out to be the glue they used to mount the sealing carpet. There are a couple of places they must have used too much and it came through. It's been like that for seven years now with no change.

I found a product called Proxi at a janitorial supply shop. It was recommended by the local RV shop. It is a stain remover for carpet and upholstery which contains some peroxide. What I found good is that you spray it on and walk away. You should never rub that ceiling material or it can leave marks. I had a small leak around our skylight and the material showed the brown from the leak. After about 3 times of spraying this on, it was gone and there was no sign of it anymore. I would highly recommend this product for the ceilings. PS, did some carpet stains around entry door and they cleaned up well
