god i remember using carb cleaner for everything till it took paint off one car.
Goo gone is bad ass. gotta use a lil elbow grease.
But really as long as you have a steady hand you can use a razor blade. that's actually the easiest but just be carefull. if it's big drip spot you could always mask off around the big ones to help protect it. after you start popping a few spots off you will just know the angle and force needed. but if you're scared bout taking a blade near your paint do the goo gone.
