you either lives close to the ocean (area like Florida) or have a broken moisture barrier on the headlamps, the latter is unlikely if happens on both headlamps. I am talking about a rubber flapper that allows moisture to escape but not in.

You can always buf the outside, that usually improve the condition of the headlamps. I don;t have guts to open it, I heard older headlamps like prior to 2004 can be baked and opened. but my concern is how are you going to regulate the temp(even if you know the exact temp to soften the seal/glue) in home oven, it can be off as much as 10% then cycle up-down, too risky.

How about just remove the headlamp, use micro-fiber sprayed with glass cleaner around a tongue and buff it slowly, insert the tongue through the H7/DS1 xenon bulb opening.
