How to remove sticky labels from plastic without scratching First, try soaking the label in hot water for a few minutes to soften the adhesive. Then, use a blunt object like a butter knife or spoon to pry the label off. If that doesn't work, you can try using some Goo Gone or petroleum jelly to help loosen the adhesive. Finally, use a dishcloth or paper towel to wipe off any remaining residue.
