When you want to personalize your car window with vinyl decals, it lets the world know a little about you. However, when it comes time to sell your car, you should present it to prospective buyers in a clean and pristine condition. Remove all vinyl decals from your car windows using these steps.
Note the temperature of the air around the vehicle. Vinyl is naturally more flexible when it is warm, so wait until a warm sunny day and park the car in the sun for about 30 minutes. If it's colder, try aiming a heat gun or hair dryer at the decal for five minutes.
Hold the razor blade at an angle so the edge of the blade is just under the edge of the vinyl decal.
Push the blade forward and backward under the decal using gentle pressure. The decal may peel up with the adhesive, or it may separate from the adhesive. Work your way around the decal until you have removed as much as you can. Newer decals will come off more easily than older weathered ones.
Soak the edge of a rag in commercial adhesive remover, then rub it over the remaining adhesive on the glass. Allow the glue to dissolve for about one minute, then gently scrape off as much as you can with the razor blade. Wipe the blade off so you don't spread the sticky adhesive back on the glass. Repeat several times until the glue is completely gone.
Clean the area of the window with glass cleaner and some paper towels.
