The easiest and most effective way I have found to de-fog headlights is to use what Raimund suggested- alcohol.  
I use marine stove alcohol. You can get this at hardware or marine supply stores. Rinse out the inside of each lense housing and let it thoroughly dry. You'll be amazed how clear the lights become. Again, make sure you let the alcohol evaporate completely, or when you switch on the lights you may have flames instead.

Betreff: Cloudy headlight glass?

I recently purchased a 1990 Westie Multivan from someone in Northern
Cal.  This van, and several others that I looked at all have to some
degree or other what I would describe as a slightly opaque or cloudy
appearance to the headlight lenses.  Incidentally, now that I think
about it, all were from Cal and had made their way to more northerly
owners.  If these had a plastic cover I'd say that the plastic had
deteriorated from sun exposure, but none of the vans that I looked
at appear to have plastic lens covers.  The problem afflicts both
the high/low and high beam lamps.

Anyone have any clues?  Is this likely an internal deposit that I
can rinse out with some magic chemical, or is the glass actually
likely to be starting to go opaque?  I've never seen glass go opaque
in any other older vehicle.

I'd love to buy the euro lamps, but things like new tires and front
brakes are going to take priority at the moment.  I'm going to have
to live with these lamps for a while, so I'd like to clean them up
if possible.

Cheers.
