This is not how to clean or make clear the actual headlight lens as there are plenty of information on that.
This is how to clean the little projector lens inside the headlight.
It is also suitable as a How To repair lights damaged in the post.
I had just bought a pair of projector style headlights, as usually happens one of them had been damaged in transit. As I had to take one apart to repair it anyway, I took the chance to clean the projector lens too as it appeared cloudy.
Firstly you need to open the light unit. Do this when it is cold. The lens is stuck to the housing using incredibly tacky black, blue tak like stuff. When it is warm it is stickier, so best to do it when cold as it is more brittle and comes off the plastic easier.
I pried the lens away from the housing using a couple of screwdrivers while lifting the securing tabs. It is a bit of a three handed job, but you will get there in the end. This does leave marks on the black plastic housing, they will not go away, but are not a problem when assembled as it is covered by the bumper. If you are not happy with this, don't do it.
The chrome insert is held in place with three ball and socket efforts, two at the top and one at the bottom. The bottom one is the height adjuster motor, one of the top ones adjusts the left and right positioning of the light, the third is fixed.
Simply pry against the black housing again where the white sockets are in the chrome insert and they will pop off. Once you have removed all three, you will have these two parts.
The projector lens is attached to the chrome insert with three screwed in studs. Do not undo the nuts that hold the projector lens to the studs, simply undo the studs from the chrome insert. They spin in the projector lens, the nuts on the studs are lock nuts and if moved will move the lens out of alignment.
When you have removed the studs you will get two parts
On the headlight I had posted to me, the fixing points for the projector studs had sheared off the chrome insert. I used a very strong glue to hold them back in place, I wouldn't cheap out on this stage if you are repairing the lights as it will just break off again.
While the projector lens was off, I was able to inspect the beam pattern adjustment, as they are adjustable for a flat beam pattern for use when driving abroad.
Now simply polish the lens, a nice clean lint free cloth. I used no cleaning agents, just the cloth and the muck polished off brilliantly.
You can now reassemble the headlight, which by now should be pretty obvious how to do it. Once you have put it all back together, you will need to re-seal the outer lens to the black plastic housing using clear silicone so that water doesn't get in and ruin all your hard work.
Remember not to leave any fingerprints inside as when assembled you will not be able to clean them off!
Stand back and be impressed!
