I recently polished my car's headlights because they had gotten quite foggy. I learned some things that I'd like to share, and the results are pretty impressive.
I used a Turtle Wax Headlight Restorer Kit that I got on Amazon for $7.99. This kit comes with a lot of things, but I only used half of them. The results I got aren't perfect, but they're pretty good considering I only spent about 30 minutes doing this.
First, I used some water and a clean old t-shirt to wipe any dirt off of my headlights. The kit includes a "Lens Clarifying Compound" which I then applied in small dabs about the size of a dime every 4 inches or so. I rubbed the restoration compound into the headlights in a circular motion until I couldn't see any more compound on the headlights. I repeated this three or four times using a clean section of the t-shirt each time. Finally, I buffed the headlights as much as possible to make sure there was no more clarifying compound on them.
The headlights were pretty clear after that, so I called it a day and skipped the next step. (So I didn't use the "Spray Lubricant" or the "Restoration Pads".) I opened up the "Lens Base Coat Wipe" and wiped it on each of the headlights. After waiting a couple minutes for the headlights to dry, I opened up the "Lens Sealing Wipe" and wiped it on both of the headlights.
My headlights still have some chips in them from rocks, but they're no longer foggy.
