In Australia, we use eucalyptus oil, which you can buy in the supermarket. I don't know if you'll be able to get it in America.
Another product we have is called Zoff, which you can buy in a pharmacy (drug store). Doctors usually use Zoff for removing adhesive from bandages and for removing plaster when they have applied a cast to a broken limb.
