Hello folks,
I used Iron-X for chemical decon a month ago. Some of which flowed down the rear windshield. I cleaned it up before drying out (as soon as I noticed it was running down the window) but it left the streaks. Anybody knows how to remove those streaks? They are usually not visible but on cloudy days they are more pronounced.

Any idea to clean these streaks are welcome. The vehicle is 2015 Forester, if that matters.
