its not hard to remove tint at all... for the side windows use a razor blade and cut at the top of the tint to get a little edge off... then you just pull it off... you will have the glue residue all over the window... all you need to do is get baby soap (no chemicals) and clean the windows... for the rear windshield do what CreativeDesignZ said but you don’t have to use a 50/50 solution of ammonia and water... you can always just use baby soap (no chemicals)
