Center Gauge display - clear one day and foggy a few days later

[cbenz1]

The glass on my center gauges went from clear to very foggy in less than a week.  I can do the work to get it out and clean it, but my worry is the root cause.  Is it possible that something inside (maybe oil pressure) that could leak and smudge the gauge glass?

Most likely it's just moisture.   This has happened to my center gauge glass after a rainstorm (when I was driving) and then leaving it in the warm sun for a while - it went away and hasn't come back.

Mine was in garage under a car cover....but you are right - cleared up to almost perfect.  Enough so where I am not going to mess with it.
