Headlight cleaning

I was wondering how to make the headlights more clear looking. I heard of this stuff called Zaino plastic or Zaino glass cleaner...? Or i also heard that some kind of silver or chrome cleaner (can't remember what it's called), can be used on the headlights too. Anybody know what im talking about?? Help!

i've used buffing compound and it worked great

Go to the auto store Find Plastic polish it works great on headlights if slightly cloudy. If worse I would go and try to find the deep scratch plastic polish it works much like rubbing compound takes out deeper scratches and cloudiness. The inside is much more difficult and takes some patience and engineering to accomplish.
