3M makes a product that is very good for removing adhesive. I buy it at my local trim supply wholesale house. It is called 3M General Purpose Adhesive Cleaner Part No. 051135-08984. According to the can label it is for removing: adhesive, silicone, wax, grease, tar and oil. I have used it successfully to remove the yellow colored type of adhesive that is used in the upholstery business and for weather stripping. It works very well without much effort.
Good luck!
