Dust inside front light lens

[judibake]

I just purchased a 2001 966. The outside of the front lens is shiny new but the inside has a thin layer of dust that is noticeable and must interfere with light transmission to some extent. Is there anyway I can get inside the lens to clean it?

Try this - remove the light "cans" from the car. Remove all the bulbs and electrical wires from the light units. Fill them up with water and rinse several times...then blow them out with a rubber hose attached to your air compressor. The rubber hose let's you run it back up into the light unit without scratching anything. Let dry overnight, reinstall the bulbs and electrics, reinstall the lights. There you go!

Thanks for the advice. I will try your method and report back to the site. Someone else suggested the irrigant be a combo of distilled water and vinegar. Have you used this method yourself?

Headlight douche. Now that is something I haven't tried!

My experience - cool clear water, distilled would be best as there are no minerals that could leave a deposit. Blowing them out with compressed air ensures no water droplets on the inside that dry and leave a spot. Let me ask you this - would you clean the outside of these $700+ light units with a water/vinegar mix and possibly damage the acyrlics or coating? Same goes for the inside. Not a good time for an experiment! When doing something like this, best to be as gentle and safe as possible. If it is just dust, then they should rinse clean. If it is slightly pitted from the burn off of halogen gas from the bulbs, then you either have to live with it or replace with new light cans($$).
