Window Gels staining
Anyone got any ideas? Friend just emailed me she had some window gels on the east facing window and with the hot summer they did not hold up well. Left stains and dripped down too. So far she has tried window cleaner and tried vinegar, these just smeared. I told her to try a single edge razor blade and see if it will scrape off.
I'm hoping someone here has a better answer for her.
