I've been decorating and stupidly put a bag of rags on my lovely big wooden chopping board. They had been used with white spirit to wipe up paint. The bag had a hole in and there is a big oily stain on the chopping board and it reeks of white spirit. 
Is there any way to get it out? I'm worried about using stuff to clean it because of mixing chemicals etc. If I just leave it will the white spirit eventually evaporate and leave the board safe to use?
It was bloody expensive too. (the board not the white spirit).
