In Australia we use eucalyptus oil on all gooey sticky things, mostly labels removal, try a little on a cotton bud in a place you can't see. Or try rubbing it with a little turpentine wash as soon as possible, a lot of presoakers might be worth a try.
Rubbing alcohol, fingernail polish remover with acetone (depending on the material), Goo-Off or you could try setting ice on it and treat as if it were gum. Let the goo freeze and then scrape it off with your fingernail or gently with a butter knife.
Use GOO GONE -- works like a charm
Thanks for the polish remover, it came off like a charm.
