What's the best thing for cleaning the hammocks with?

I've been trying to clean up the white vinyl wrap thingy that goes around the bunks, nothing is making it come up very clean, what's the best thing that you've used?

Sugar soap.

Hahahahah

 

give cillet bang a go, seems to clean pretty much anything!!

 

Oddly enough i used saddle soap and it worked???? Mind you it was pretty dirty and any soap may have helped.

 

Thanks for the advice, my Flash just wasn't cutting it! Even tried Upvc cleaner and that didn't shift it so ill try your suggestions

I used it to clean up some white/cream vinyl mouldings. Put it on neat and leave it for a while then scrub is with a sponge or nail brush, rinse and bobs your uncle.
