I've seen this on sets that have never seen ANY cleaning agent.
Indoor or outdoor?
I've seen outdoor TVs that got some rain water on the screen. And at some point it streaked the screen. Not sure if it was chemicals in the run-off from the roof or maybe acid rain? Customer lived with it at that point, you really couldn't notice it that much with content playing.
