Headlight reflector cleaning

[KMBeers]

I have been looking at my headlights and the reflectors are “dull”. I am not sure if they are the original silvered coating, a repop chrome, or the polished aluminum, but they are dull. I have tried a paste wax which cleaned them a bit, the polish applicator had a black residue after finishing, and just soap and water. Nothing helped so I am wondering what others have done.
