 Having not been able to see it, I don't know if I can identify it for you. If it is on the inside, and you're talking about in between the two panes of glass, correct? That's correct, because I washed it twice, and those streaks stay there. I tried to take my fingernail on it and didn't have any luck. So, I mean, I hadn't washed the window in a long time. Probably dirty, very dirty. Maybe didn't notice them, Gary. Yeah.
