How do I get a stubborn sticker off my shirt?
This question reminds me of the time I wore a nice rain jacket to a skating birthday party and the host slapped a sticker on it. When I pulled the sticker off, the finish on the jacket went with it! I would try soaking the shirt with liquid Clorox2® Stain Remover and Color Booster: add a capful to 2 gallons of water, and fully submerge the shirt for up to an hour if it is colored, or overnight if it is white. This should dissolve the adhesive that is holding the sticker. If it is only partially removed, then you may need to try Goo Gone® or De-Solve-it®, which you can find at hardware stores. Just be sure to test the shirt for colorfastness.
