Alcohol and cotton balls. Saturate the cotton balls with the alcohol, let it sit on the decals for a minute or so. Peel the decals and reapply alcohol as needed. This will remove the decals and any sticky residue.I am an owner of 9 cars. I can not stand "dealer decals" and this works EVERY TIME with little effort and no damage.All else fails, take it to an auto detailer and they can fix you up.
