Sorry about the board Joko 
For what it's worth, this thread is still good for future folks who may be dealing with the same issues; saves from making a new thread all about "how to get the 80s funk out" every time somethings a little smelly
My go-to (aside from the usual simple green wipe down) is Gain scented drier sheets! Rub the sheet just a little to break the stiffness and throw a bunch in a bag with the board and let it sit for no more then a day. Doesn't need to be air tight, but does pretty great for for me in getting the old mothball smell out of Ebay things!
