They all do it over time.

I think the bulbs give off something almost atomic, and it forms an ultra thin coating, or.... maybe the heat from the bulbs affects the glass chemically.

Either live with it, or buy new ones.

Cant say it bothers me much, and I am mega OCD.

The fog lamp lenses are made of toughened glass, not polycarbonate, considering where they sit, they get pitted and therefore become fogged.
This kind of glass can be polished to as new an appearance using Cerium Oxide paste (ebay) and a small high speed polisher, make a paste to suit so long as it is kept moist as the process of sanding creates considerable heat\ polish in 1 minute runs, will take a while but with patience great results, keep glass surface moist at all times during polishing.
