I have put this off for years because I didn't want to ruin the footboard but now we're redoing my son's room and it has to go. For whatever reason, the manufacturer put a huge sticker on the inside of my son's wooden bed frame. It is light maple. I need to get it off of there, it looks terrible. But when I look online I get conflicting information - some sites tell me to use vinegar -- some say use Goof Off, others say don't use that, it will ruin the finish, use WD40 instead, others say to use something called Un-Do Adhesive?.....

Does anyone know the best thing to use that won't ruin the wood?
