What's a good way to remove sticker residue from a shirt?

Question

I left a name tag sticker on a polo shirt, and accidentally put it through the washer and drier. It left a really nasty residue in its place, which is very difficult to remove. Any suggestions on how to remove it?

Answer 1

Spray n Wash Laundry Strain and Removal (Stain Stick) should get it out.

Answer 2

Place in a plastic bag and pop into the freezer for a couple of hours. Should just scrape off. Be sure to be gentle!

Answer 3

Try some rubbing alcohol...

Answer 4

Try goo gone.  I highly recommend it in the spray version for this purpose.  Just spray on and the sticker residue should come out very easily.  Make sure you wash it very soon after though as I do not know if it would discolor after awhile.
