carbon soft vault

I have an X Metal soft vault that I bought second hand. What's the best way to clean the outer nylon without affecting the glue or causing other damage?

Hey guys and gals, greetings from the UK. Last year I lost my Juliet large (X) carbon soft vault in Animal Kingdom and have been unable to find a replacement. Does anybody know of a 3rd party one that will fit as I've spent 9 months trying to find one and I can't face mine being damaged. Thanks...
