Removing window tint is probably not because you want to, but maybe you got a ticket or fine and are being forced to take it off. Or maybe you want to go darker or just sell your car to someone who does not want it on there. Either way you want to remove the film from your ride and would like to know how to do it without damaging your windows.
The best way I found is to use ammonia and soak it on the windows for a few hours. Let it bake out on a hot sunny day when it can really do its work. Sometimes I would cover it with some kind of plastic so it does not evaporate as quickly. Other times I just spray it on there good. Be careful not to get it on your interior as it could do some damage.
Whether you got limo black tint or lighter ones, they all come off the same. I normally start by using a razor blade and seeing if I can get under the top of the glass and start to get some of it peeling off before soaking it. Be sure not to do this too hard or you could scratch the glass. Take your time and allow the stuff to soak into the tints and sit in the sun.
Some people also try heating it up with a hair dryer or other tool, but I cannot verify how well it works. The key here is patience as it may take a good part of the day for the film to get good and loose. No need to rush it as you do not want to scratch the glass.
Also, once you remove the films you should not get your windows tinted for about a month. The residue and chemicals used will make it harder for the new stuff to stick and will cause a bigger risk of getting air bubbles trapped in their. No one wants to have that so just have patience and wait to re-tint them.
