1952-59 Ford Advice-cleaning inside of headlight

One of my headlights decided to blow a halogen bulb. Now, the inside of the light is cloudy/foggy. There’s not much access room for cleaning. Is it possible and what do you recommend?

Thanks in advance and sorry if this is a repost. I searched but didn’t find anything.

 

You might try the old coffee pot cleaning trick. Use a squirt of dish liquid soap and a handful of shaved ice through the opening. Shake and swirl until spotless, rinse and let dry. This supposes the lamp is removed from the car. Duh.

 

It is and that’s a good idea. Thank you!
