I have used a sponge soaked with isopropyl alcohol for this. Hold the sponge against the fabric, do not rub. The sponge allows you to work overhead and it concentrates the alcohol in the right places. It takes a few minutes but the sticky will lose its hold after a bit. You can then pick it off rather easily. Pull it off, don't rub it. I have also used very sticky tape to aid in pulling it off.
