Discolored window laminate?

[deco_droid]

This could be an issue on multiple years, but on my 50, I noticed on the open edges of the door windows and vent windows, there is slight discoloration coming from what I assume is the laminate sandwiched in the middle of the glass. It is slightly tan to light brown in color. Doesn't REALLY show all that much since it's barely 1/8 of an inch into the glass in places, but I was wondering if there was a way to clean or "bleach" this without ruining the glass. Haven't seen a topic on this so I thought I would ask. Thanks.

Doubt it. Consider it a sign of "original patina."

Not much of anything that you can do for it. It will get worse over time. New glass is the cure.

Any one ever try sealing the edges?
Wonder if that would at least stabilize the damage and/or slow down the progression?
Probably not worth the effort on a windshield, but what about the exposed edges of door and wing glass.

Old timers use to paint the edges with white lead paint, they claimed that would stop the spread.
