How to peel off a car window sticker ?

A blow dryer and a razor blade. I'm a window sticker freak, changing them several times a year. My window also has wires, but they are embedded in the glass so the blade and heat cause no problems. Good luck.

If it is on the inside over your defroster wires it is going to be hard. Carefully loosen and lift the edges with a razor blade avoiding the wires. Wet a paper towel with Goo Gone and work it under the edges you lifted with the razor. As the glue softens pull slowly without tearing. When you gain a little add more Goo Gone.

Normally over time the stickers that are applied to the inside of windows go hard and crack. They can be a pig to get of and you need to be careful not to damage the rear window heater elements. The best way to do it is to soak the sticker with nail varnish remover and then try to scrap the sticker of with your nail. Don't use a scraper or a credit card as these will damage the heater. Ja.

Peel as much off as you can and use a solvent to dissolve the adhesive that get's left behind - something like acetone or methylated spirits. You could use petrol but it stinks. Obviuosly don't smoke whilst you're doing it and wear rubber gloves as solvents will dissolve the grease in your skin that keeps your hands soft and flexible.

use a razor blade...be carefull of the demister wires by laying the blade as flat on the window as you can.

Try a heat gun or hair dryer. Gently peel off sticker.Use denatured alcohol to remove glue residue.
