Adhesive residue removal from a car window isn't a difficult task, but it can be an annoying one. There are a few ways to do it quickly and without much fuss.
Step 1 - Try a Homemade Remover
Most adhesives on auto glass can be removed by rubbing them with an eraser (just a regular pencil-type eraser). This method works well, especially on the adhesives that are a rubbery substance.
For other types of adhesives, try using fingernail polish remover on a rag and rub until the residue comes off. Mineral spirits and paint thinner will also remove adhesives and should be used in the same way. You also can try pure white vinegar or ammonia on a cloth. Be sure to leave the windows open for ventilation.
Step 2 - Use a Commercial Remover
If home remedies don't work, you can purchase several products that will quickly and easily remove adhesive residue from a car window or any glass surface. Commercial residue removers have a strong odor that some people don't like to work around. You also must be careful not to drip the cleaner on fabric upholstery because it can leave an oily spot.
