White interior roof water stains

[95monaco]

Just wondering if someone has already had to remove a water stain from the white fabric ceiling from a water leak.
Thought I had a good seal around the Air Horn mountings but not good enough and this year we have a pretty bad stain. This one might have to be sprayed with a fabric dye but thought I’d ask and see what others might have done.
97 Dynasty that been in the family since new so all in all pretty decent shape.
Thanks in advance.

Several years ago, someone posted a spray on product from Amazon that made the white fuzzy ceiling look new again. It had a strong odor and required going outside after using, but it really worked well. I can't find it in my order list as it's been too many years. Hopefully someone will remember exactly what it was.

I think it was this:

Oxyclean dissolved in water, sprayed on liberally and left for a bit and then blotted off, takes many stains out of ceiling fabric. Test it somewhere not overly noticeable first.

Thks will have to check that one out.
Clearly some trial and error will be involved as I had tried some foaming carpet cleaner that really did nothing.

Folex gets top votes and reviews here for ceilings . If you do a search you can't find many posts on same subject.

What about these stains at the joints in the ceiling?

I have used Folex spray on carpet stains. Think hair balls from my cats. It can be purchased from Home Depot or their web site. Follow the directions and this should help you.

Wow! That is indicative of an air leak! You see this all the time in the attics for homes that have a lighter covered insulation packed around the register boots in the attack where there is a gap between the boot and the Sheetrock that wasn’t sealed well.

Yours could be the result of differential air pressure while the coach is rolling down the road. Ceiling fabric makes for a pretty good air filter over time.
And while I didn’t check to see what your coach is, that sure looks like diesel exhaust (could be gas as well).
Strange differential air pressures occur when big boxes travel 60-70mph down the highway (think about that empty beer can thrown into the back of a pick ‘em up truck does - it just rolls up at the tailgate then speeds toward the cab of the truck before dropping back to the bed of the truck and starting the cycle all over again).

Tim while I’m not sure of the cause of those marks however they look like it’s on the seam of the 4 ft panel.
On our 97 Dynasty that my Dad bought new a few of the roof panel joints created those same marks.
So after a trip back to the factory at Coberg this is the Factory fix.

Had much the same markings on the ceiling of my 93, right at the seam. Air was passing through that seam, ceiling was filtering the dust out. Keep it very dry, hold a shop-vac hose against it for a bit. That took the bulk out, and I could wash out the rest easily.


(Decided to leave the seam as it was. I'll have to vacuum it out again in 28 years.)

Thank you guys. I will try the shop vacuum and if that does work I will be looking for some matching wood strips.

Folex has been around a very long time. Used to us it back in my carpet cleaning days - way longer ago than I'd like to admit.

Oxy Clean will work too, as will any hydrogen peroxide based cleaner. LIGHTY spray and blot. Don't try to get the stain in one go. If you over wet, you can draw more stain from the base. Use a white rag to blot and use some pressure on the towel or rag. You'll see the stain transfer to the rag. Refold and blot with a fresh side. Resist the urge to scrub. If you do, be gentle because you don't want to damage the fibers. Let it dry and try again another day. Little by little the stain will get drawn out and the peroxide will bleach it too. Eventually with repeated light cleaning it will fade away or mostly away.

You can even use hydrogen peroxide you get at the drug store. Dilute it with some water and do the above steps. If you use anything with soap or detergent, follow up with plain water to remove soap residue or it will attract air born dirt.

With any bleaching liquid be careful for drips on fabric or carpet below. You don't want to bleached spots showing up later in a colored fabric or carpet.

We just got through cleaning my sons motorhome that had grease and oil stains as well as some water stains on the hullliner material. It is actually very durable and we used good old simple green and a brush an then. A carpet extractor. Worked very well cleaned 95 percent off what was there
