I've been experimenting with this (and make sure its Goo Gone and not Goof Off which will take off more than just adhesive) and suggest the following:
1. Don't use much Goo Gone - a dampened Q tip ought to be enough
2. You may still have a little adhesive on the canopy rather than Goo Gone per se. It isn't terrifically potent (which is a good thing) so a second application and gentle rubbing may be required.
3. Once the adhesive is gone, finishing up with a little detergent (dishwashing liquid, 409, etc.) and water, again applied with the Q tip ought to take care of the Goo Gone itself.
