Just thought I'd add to this thread.
I'm trying to get away from using chemicals to clean my boards up so I picked up one of those Wax Pickle things. Works real well. I hear you can make your own out of a stocking or tights, pantyhose or whatever you US folks call them and some PU foam dust from your local shaper or even some flour. I think the Pickle is probably a bit safer to be using than fine PU dust but that's your call.
