Vinyl cleaning advice

[Westerham Womble]

Our Moho has large areas of silver/grey vinyl on the body and I'm really struggling to work out what to clean this with.

Most of the vinyl has mottled and gone matt and is covered in what looks like limescale from water marks.

Its only 4 years old, I used a layer of Collinite 476 a couple of years back and its deteriorated badly since then so I'm guessing I shouldn't have used this on vinyl.

I've tried using anything I can think of to clean this up with absolutely no success so far

Any help would be appreciated, current thought is to try a clay bar next ?
I've tried T cut, white spirit and acetone (all on small areas)

Help

Some of these vinyl finishes are a nightmare to keep nice to be honest, we have friends who had a Concorde and the silver grey on that went all cloudy and nothing would touch it.

I got some polish on our textured black vinyl and it went white and cloudy but cleaned up nicely using a "magic sponge" with some car shampoo on, I have all sorts of special potions that are supposed to keep it looking good but I have found the best is just to wash with wash n wax and then dry off with a towel.
