You can remove the tint yourself if you have something that creates
steam. Warm/to hot very moist air starts the process, and makes removal
much easier. Dish washing soap and water, with something like Windex, or
a very small amount of ammonia added to the dish washing solution also
helps, and should be repeatedly sprayed on the film. Patience is the
word. Don't scrape any heating grid elements. Generally, you would get a
corner of the film to lift, then spray the warm/solution on followed by
steam, then, after a bit, gently pull on the corner until you feel a
change. Spray some more solution on, add more steam, wait, and as the
film loosens, gently pull again. Once the film is off, there may be some
of the glue remaining. The same process can be used to remove it. You
can also score the film with a razor blade to help the solution/steam
penetrate, but it's easy to scratch the glass or the heat grid elements.
If you have a plastic window, test the solution on a small unimportant
area first. Ammonia can cause problems with some plastics and fabrics.
With the plastic windows, and high heat areas like Texas, some plastic
films can
be a real problem to remove, and cause window replacement to be necessary.
