We're dealing with the dirty vinyl walls issue too. At first we sprayed on and wiped Simple Green but they still didn't look as clean as they could be. I diluted some Mr. Clean in warm water then used our electric scrub brush (best invention ever!) to scrub the walls. Some of the stains are permanent but the dirt is definitly gone.
The guy who painted our house swore by it. I saw it recommended on another thread, so I gave it a try on our sticky, vinyl clad walls. Worked great! Give it a try!

Behind the built-ins in my rear bath AS was original & never cleaned - I can't comment on anyone elses trailer since the last cleanser used always leaves traces behind that can mutate the surface deposits to take on a life of their own. What best melted away the grime that was scaring me was a 1:4 dilution of Krud Kutter applied and wiped off, then follow with full-strength Goof-Off 2 scrub - the Krud Kutter perfume is pretty noxious but the Goof-Off 2 is unscented and conquers the industrial perfume of the Krud Kutter..
After removing the panels I used a light sprinkle of Bon-Ami scouring powder on dripping wet panels, scrubbing with soft sponge, and then hosed them off & was amazed at the amount of oxidized vinyl that was removed, very much brightened the surfaces from what surface-spray liquid cleaners left behind. A wet soft sponge with a light paste of Bon-Ami suds action will work wonders maintaining in-place liners as long as you have enough towels to wipe surface clean of the Bon-Ami AND then do a wet towel rinse and then towel dry...
The vinyl surface of our '69 Overlander was sticky when we acquired it 11 years ago. We scrubbed it with house hold cleaners (fantastic or something like that) and have not had a sticky problem since.
As we were about to leave from the PO that we purchased our Tradewind a year ago the lady grabbed a spray bottle of 'Patio Furniture Cleaner' and handed it to us. She says that it removed years of grime from the walls of our 'new' clean AS. However, I suspect that all cleaners for vinyl are made of the same ingrediants.....maybe by the same manufacturer.

In a purple gallon jug at Walmart automotive. Make sure you get the concentrated soap-do not get the concrete cleaner.
After you dilute it 4 to 1, you have an extremely powerful cleaner, 45 gallons for about $6.
Use rubber gloves, and a spray bottle. Even after using other cleaners, you can see a brown residue form almost as quickly as you spray it on.
The spray droplets are pretty potent. Spray gently, and rinse well. I've used many of the froementioned, and I swear by this stuff.

Have no intention of arriving at the grave safely, but rather to skid in sideways, chocolate in one hand,throttle in the other, totally worn out and screaming
"WOO HOO, WHAT A RIDE!"
The vinyl wall coverings contain two plasticizing liquids which oxidize with age and become incompatible with the vinyl. They the "spew" to the surface. They then further oxidize and become sticky. It is only a matter of time and temperature till it occurs. You need to solubalize the goo. Spray Nine is a good material to use. Once you have got it all off, you can seal more from coming out of solution by using a acrylic liquid latex polish like floor polish to retard it getting sticky again for quite some time. As the vinyl loses its plasticizer its volume is reduced and the wall covering will shrink and come loose from the edges where it is weakly adhered. It may also shrink non-uniformally and form wrinkles in the paper. This is particularly a problem when the vinyl is applied to the plywood partions because the plywood also draws the plasticizer out of the vinyl and the adhesive they used was not especially good.
