I have an 08 XTX which has developed an amazingly sticky seat.
The bottom of my jacket has become sticky, also the cheeky bit on my bike trousers. I have Gel inserts, but the sticky seems to be All over the seat, as if someone has sprayed something on it as a joke.
Anyone else have experience in the sticky bottom department?
What is it that has made it so?

I've tried washing with washing powder+water, no joy there.
I can scrape black off with my finger nail.
