Article: To remove stubborn adhesive residue, dip a corner of the microfiber cloth in rubbing alcohol. Once again, use tight, circular motions to scrub off the sticker goo. If glue residue is still sticking around, dip your cloth in alcohol (or vinegar diluted with water) again. Place the cloth onto the sticky area, and let it sit for 2 to 3 minutes. That should dissolve any remaining stubborn gunk. Rubbing alcohol shouldn’t discolor or damage the plastic or aluminum used for laptop casings. However, if you want to stay on the safe side, check the area every 30 to 60 seconds. Cut off a 2 to 3 in (5.1 to 7.6 cm) piece of duct tape (or other sturdy, sticky tape). Fold over a small portion of an end to make a non-sticky handle, then rub the sticky surface of the tape over the adhesive residue. If there’s any stickiness left over after using the duct tape, wipe it away with a cloth dipped in hot water or rubbing alcohol. Using light pressure, wipe the sticky spot with a nylon or melamine foam scrub pad, such as a Mr. Clean Magic Eraser. Soak it with water first and give it a go. If water alone doesn’t remove the gunk, try adding a drop of dish soap or dab the pad with rubbing alcohol. Rub the sticky area with the scrub pad gently. Nylon and melamine foam scrub pads are mildly abrasive, so be careful not to scratch the surface of your laptop. A blow dryer can melt and loosen glue, but it should be one of the last methods you try. Set it to low or medium, and aim it at the gunk for about 30 seconds. Then see if you can get rid of the remaining residue using a cloth, putty knife, or credit card. Even though your computer is off and unplugged, you don’t want to risk overheating it or damaging its internal parts. Stick to a low or medium setting, and use it in 30-second intervals to avoid getting your laptop too hot.

What is a summary?
Use 90% rubbing alcohol if the damp cloth didn’t do the trick. Hold an alcohol-soaked cloth over the area if wiping it didn't work. Slide tape over the stuck-on residue if you didn't have luck with alcohol. Try using a mildly abrasive scrub pad if a cloth didn’t work. Use a blow dryer to loosen the gunk if all else fails.
