Can anyone tell me what I can use to clean the inside of my Headlight casing?

 

they have stuff at any auto store to do it, its like a wax and it really helps clean it up

 

I have Blue Magic Headlight Lens Restorer and it worked well on the outside of the lamp but what can I use to clean the inside?

 

Are you sure it is on the indside? i thought mine was like that but it was just a really deep stain onthe outside. Rub your hand against the outside of the lens it should feel perfectly smooth. If it doesn't you may need to wetsand the outside( thats what I did and they look great). If it is on the inside you can probably use whatever you used on the outside just bake them to release the glue holding it in.

 

that build up happens if you dont change your headlight fluid regularly [8D]
