Have a insulated window that has fogged up... between the 2 panes of glass.
Changed 6 windows approx 5 years ago, this is the only one that has done this.
It is on the north side, along with 3 others. (Louisiana)
Besides replacement, any ideas how to clean this ?
How does this happen...
I thought this was sealed and nothing could get between the panes.
