No, Goo Gone is orange/citrus oil, Goof Off is about 90% Xylene.

Will doing so to the bottom have any ill effects? Should I just try to rub it off with my thumb?
This may sound dumb, but have you tried water and dish soap? If it is indeed grease pen, then it should come right off with a little detergent.
