CLOUDY PROJECTION/PROJECTOR HEADLIGHT LENSES

Is it possible to remove the lens and reflector unit from the Roomster headlamp assembly? I only ask because mine are very cloudy and, when googling topic, I came across a video showing how easy it was to unscrew and remove the complete lens and reflector unit from an in situ truck headlamp. Both sides of the lens were very dusty as well as the reflector and they were returned to as new condition with nothing more than a good wipe over with isopropyl alcohol. The difference in illumination was amazing. Instead of a dim, all over spread of light there was now a sharp beam. I want some of that. So, can it be done on a Roomster?
