My windshield has a parking permit decal on it. How can I remove it without damaging the windshield?

 

If its a harley tinted one, hope its not on tint side. Is it paper or plastic?

 

try heat,,a little at a time you dont want to warp the windshield,,you can try a hair dryer first,,heat as you pull,,,it should come off,,if it leaves glue,,try heating the glue a little and use the sticky side of some tape to pull off the glue,,,or you can just cover the spot up with a sticker that you like,,,,just a thought,,,

 

Goo gone or WD 40 should work
