How to clean up headlight covers?

[the_mini_mole]

Hey guys and gals, my headlights are going a bit hazy, does anyone have any suggestions as to how I can polish them back up to clear. I looked at autoglym glass polish but it says its not suitable for plastics... Has anyone tried polishing theirs up?

you can use like any compound to cut the plastic n give it a sheen again mate, like mop them over once i do to my headlights makes them really shiny, maybe try t-cut on a small area first as that is a compound restorer!
