brittle window film

I have a condo in Florida that has some type of film on the windows. I think it is from when the condo was built, so about 30 years old or so. It has become foggy and brittle and I'd like to remove it. I've seen suggestions to use a hair dryer, however, this is so brittle it that method doesn't work. I tried using a razor blade scraper, but besides making a a big mess, I see some scratches in the area that tried that method.

Any suggestions? Thanks

Plastic that old isn't coming off easily ore in one piece. Razor blade and clean up the mess is probably the easiest way to remove most of it. Your hand will soon cramp holding onto a single edged razor blade. There are tools that hold razor blades and will make life much easier.

As for the mess you can hold the hose of a vacuum nest to the blade as you scrape off the plastic. I prefer to put down a drop cloth and scrape away. Then shake out the drop cloth over a garbage can.

Residual plastic and adhesive can be removed with solvent. Make sure to mechanically remove as much as you can before attempting solvent as the solvent can turn the plastic bits and glue into a gooey mess. The more you remove mechanically the less goo there is when you clean with solvent.

Make sure your razor blade is sharp and is not dragging debris as you use it.
Also use warm soapy water as a lubricant when using the razor blade.
Use short strokes with the blade,

Thank you both for your comments. Sounds like some scraping is the best option. I'll try using some soapy water to help lubricate and keep the razor blades fresh.
