For clutter's sake, I'm trying to completely wipe my wishlist, but can't figure out an easy way. I'm not online nearly as much as I used to be, and it is no longer an accurate representation of what I actually need/want, so it's just a very long list of seemingly random items and that drives me mad! I've been able to delete all categories bar one, 'unsorted', which is a mile and a half long. I really don't want to waste my life manually deleting each one... Please tell me there is another way to do this.

Nope. There is not. And with deleting the categories, all items in them should be back in unsorted. :/ (except you deleted them before..)

I am not sure if they still do it but a year or so ago you could file a ticket and ask an admin to clear your wishlist.

Thanks - in that case I might just put this in the too-hard-basket and ignore the problem and hope it goes away ;_;
