+1 I can still smell that smell and it been years since I have pulled any off...LOL

 

The best way Ive found is wait for a really sunny day, cut a black trash bag in pieces to fit closely to the size of the windows. (you can lay the trash bag on the outside of the window to measure size) Then, spray windex or anything with ammonia in it all over the inside of the window. Carefully place the trashbag against it and work out as many bubbles as you can. Make sure it is covering the entire window and parked in the direct sun. Close all windows and doors and let it "bake" in the sun. After 30 minutes or so you should be ables to pull the tint off with the trash bag very easily along with most of the glue. Any glue left over you can use goo gone with 0000 steel wool. (NEVER use steel wool or razor blades with a dry window) This works especially well on the back window without harming your defrost. Also since you are spraying the rear window liberally, you may want to put some down over the back deck so it isnt dripping all over it while you are trying to cover it witht he trash bag. Hope this helps! By the way, the last car I did, I didnt need a razor blade once.

 

i used gue gone and a razor blade, took around 1.5 hours to do both my side windows.
