hazy headlight reflectors

[cheesebox]

Is it possible to remove the haze that seems to build up on the headlight reflectors over time? It spoils the look of the car - would be nice to get the lights looking like new again. I assume you need to remove the glass front, or can it be done another way?

You mean the white powdery stuff? Ive washed headlamps out before with fairy liquid etc, use a heatgun to dry them out properly.

Not recomended for the projector lamps though
