Some items that remove adhesive include nail polish remover, toothpaste, hand lotion, hair spray, baby oil, vinegar, WD-40, rubbing alcohol and a hair dryer. The type of adhesive determines the right method for removing it.
If someone is trying to remove residue from duct tape, WD-40 is the best thing to use. Just spray some of the lubricating oil on the adhesive area left behind by the tape and wash it away with a cloth. For many types of adhesive, trial and error is the best method. Start with basic items like vinegar or nail polish remover before moving onto more complicated materials.
Using a hair dryer to warm up the adhesive to let it soften is often a good method for many types of adhesive. Once it is soft enough, it should be easier to wipe away.
