Many kinds of glue will loosen up if you let them soak in some warm water for 30 minutes or so. If the glue is on a window, you may need to hold the wet rag against the glue to allow it to soak. While you shouldn’t use razor blades on paint, you can often use them effectively to scrape glue from glass. Press the blade into the window about 1 inch (2.5 cm) from the glue, then slide it into the glue repeatedly to peel it up. Be careful to maintain the 45-degree angle, because if you press the blade directly into the glass, you could still scratch it.  Wipe away chunks of glue as you scrape them off. You may be able to remove all of the glue just using the razor blade. With most of the glue removed, there may still be a residue or a thin layer of glue left behind. The best way to remove it is to use a commercial adhesive remover you spray on and then wipe away.  You can purchase adhesive remover at most hardware and even many grocery stores. Be sure to follow the directions on the bottle. In a pinch, the acetone found in nail polish remover can be an effective way to break up the glue on your window. Be careful not to get any on the paint of your vehicle, however, as it will also remove the wax.  Put the acetone nail polish remover on a cloth and then use the cloth to apply it to the window. Scrub the glue with the cloth until it comes off. Whether you used a chemical to help break up the glue or not, you should wash the window to clean any last bits of glue or debris from it.  Spray on the glass cleaner and then simply wipe it away with a paper towel or clean rag to clean the window. Wipe the cleaner away in a circular motion to avoid streaks.
