How to remove window film

[Gina]

I am trying to remove some very old window film from
several windows. I have tried hot soapy water with
ammonia, acetone, and “Goo Gone”. I then scrape
with a razor blade. These all make it a little easier,
but it still takes hours for each window. Does
anyone know of a more powerful chemical or method
to use???

Hi Gina:
What is often the culprit are impurities in the water or cleaner.
A very simple test is to buy some distilled water, add a cap of ammonia per quart, spray on the glass with a new bottle sprayer and clean with a new (same day) piece of newspaper. I’ll bet your film will go away. 🙂

Best wishes
