I've just been cleaning our caravan and am really struggling with the roof.
I usually use Fenwicks caravan cleaner, with a brush and it comes up fine, but not this time! I even tried a spot test with neat Fenwicks on a cloth, and that didn't make much impact.
Not wanting to use anything abrasive I used Silky cream on a patch, which works but takes a huge amount of effort.
I have added a couple of photos showing the problem and would welcome any advice/suggestions.
