X2 Aerospace 303 for protection after cleaning. For cleaning I'd spot try Purple Power diluted. Be as non-aggressive as possible when cleaning to avoid damaging the material. Keep the Tex wet and brush in the cleaner.

Post some before and after pics if you don't mind. LA's Totally Awesome is potent but I'd only use it as a last resort and watch the fumes from it.
