The answer is 3M again : Goo Gone... It is a gel which will dissolve the gooey gunky adhesive. If that fails go for some ammonia mixed
50/50 with distilled water or some pure acetone (not nail polish remover;
pure acetone)
Do not forget to dress them well after you are finished...
One last trick : One of my buddies said he smears the trim with vaseline gel before he starts polis and wax and simply wipes it off when he is finished !!! Sounds much easier and even beneficial for trim...
