In my opinion blank boards are gay but some people like them because they dont mess up your picture on the bottom. You take off the picture on the bottom so you dont scratch it. Kinda stupid aint it?
1) Take the trucks off the board
2) Get a piece of tape and smooth it out all over the board.
3) Start to peel off the picture from the end of one side
4) Keep doing this until the whole picture is off
5) Skate on your blank board
