my family owns a 2009 Maruti Suzuki Alto. Sometime back the RHS lamp exploded inside the housing, since then the housing became hazy, although the light output does not seems to be affected much, I want to know of it is possible clean the inside just so that both headlamps matches. I have tried vacuuming after removing the housing from the body and all the big glass bits were removed, but a small layer of glass dust still remains. If you can tell me how to remove this it would be very helpful. PS already thought of stuffing a microfibre cloth inside, but did not wanted to risk it as it may cause scratches in the reflector.

I've had success in the past by removing a complete headlight assembly and warming it in a very low temperature oven to soften the adhesive that bonds the outer lens to the unit. It then become possible to carefully and gently prise the lens away from the unit allowing access to clean the inside of the reflector.
