Went to an estimate the other day and the Windows had some discoloring. I’m not sure what caused it or if I can undo it. Any suggestions?
Sorry I didn’t get a closer pic. It’s one of the first floor windows. It has an iridescent look to it.
iridescent makes me think that it’s a blown seal and the Coating in between the panes has oxidized

Can I borrow that for a visual aid to explain the home owner?

Thanks for the info by the way. I will have to look this up. This prospect lives off of well water and run it through their sprinklers. They want a house wash but the house has HUGE THICK BLACK STREAKS all over. I might be in over my head.
