Sorry if this has been discussed a hundred times over but I'm very happy with the results of this method and thought I'd share with everyone.
Started off with a very very dirty 91+ with very very dirty headlight lenses.
Here's a couple of shots of the passenger side which has not been done yet (note the yummy blue RTV used to seal the lens by previous owner...
)
And here is the result after about 3 times over on the drivers side:
It could use to be gone over about 3 more times for final results but after just one try it looked significantly better. There are some rougher spots that can probably use to be gone over with some sandpaper, but overall they cleaned up very nicely in about 5 minutes!
Here's what I used:

After cleaning headlights (no matter what method you use) I recommend waxing the headlights when you wax the car, this will prevent a lot of this crap from building up.
