i use acetone for such stuff. wear gloves. im missing big patches of skin on both palms from handling an aluminum quad rail then using acetone for a cleanup, didnt realize holes got poked in em. the acetone removed a lot of the skin oils off my hands took a month to heal.
any of the liquids that remove glues including goo gone you should wear gloves that have no holes....
however you get it off with hot water or a chemical method be sure to re-oil promptly.
dont use a razor blade you can scratch it easy
