Headlight Condensation

[SJ]

One headlight on each of my Audi's has a "foggy" lens. Stock equipment. It
is not condensation, as the foggy appearance is always there.

Can this "fog" be cleaned out by removing the headlamp assembly and washing
the insides with a windshield washer solution? Kinda slosh it around on the
inside then rinse it out.

A hair drier rigged with a copper tube would work to dry out the insides.

Anyone try cleaning the insides?
