My dear daughter and husband have done this many times (yes, husband - I hate those "Hello my name is... sticker nametags for a reason!). I spray Desolvit (spelling?) on it, let it sit for a few minutes, and toss it in the wash and it all goes away! You can buy the stuff in a spray bottle at walmart in the cleaning aisle, usually on the top shelf near the goo gone type stuff. Good luck!
