waxy wetsuit

i've got a huge white patch on my derriere where i've sat on my board.
i've been looking at other surfers bottoms, (it's becoming a bit of a compulsion) and they don't have white patches.
I'm quite embarrassed, and i guess it also shows that i probably haven't waxed my board very well.
How do I get the wax off my suit? Any ideas welcome - I was sceptical about the cardboard surfboard but it's fab - I'll try all sorts!
